I recently got an invite to google fi and I ported one of my phone numbers to there. the service seems pretty solid, being on tmobiles network and sprints network. I wanted to see if I can purchase a dual sim card adapter and then put a att sim card in there also, so on the google fi side id be on tmobile and sprint network (with 1 number), and my other cell phone number be on the att side?
ID assume myself that it should work.
A dual sim adapter would work on wcdma, hspa+, gsm and LTE. So the gsm side of tmobile and att would work through the simcard adapter, as well as the LTE part of all 3 networks. CDMA part would be programmed into the phone not the simcard. Correct me if I'm wrong?

CDMA hook is in the software. Pretty much they have to have the CDMA RILs in the software to enable Sprint and Verizon CDMA radios..
So theoretically a dualsim adapter should work on my nexus 6 with a gfi sim and a att sim?
How would a dual sim adapter fit?
That's the question that should be asked in my honest opinion.
^^ What he said
If there was one, it wouldnt fit into the phone, or it would stick out like a OTG device. Wouldnt be very usable or convenient - better off switching sims as needed.
I actually found a few. They are flex cables that stick out. Not really safe unless you have a case similar to the roocase glacier or something that has space between the back of the phone and the inside of the case. Secondly the software needs to support it.
Yeah these do work for the N6 but not for CDMA
Hi,
Just wanted to mention that I've used a dual-sim adapter with the Nexus 6 and they do work really well, but only for GSM carriers. I used one successfully with Cricket and T-Mobile SIMs and the phone did great switching back and forth and rarely needed a reboot to get it to work. CDMA SIMs *never* worked right, which I'll discuss at length below. Any wrap-around case works well to protect the adapter (the EVOCEL one works *really* well) but the SIM tray will stick out ever so slightly to make room for the ribbon cable that connects the two SIMs which can look a bit weird and disconcerting.
AliExpress has the adapters very cheap (like $3-$5 - order several as you'll probably break them a few times learning to install them in the N6) - I would steer clear of any of the expensive ones like MagicSIM as these have a tendency to break easily and asking $30-$40 for one is insulting IMO considering how delicate they are. Plus the MagicSIM one I had was the worst of the bunch and totally sucked.
Anyway, I tried a bunch of these adapters...MagicSIM and the AliExpress ones...and *none* of them successfully worked with a Verizon or PagePlus (CDMA/LTE) SIM. Sometimes you could get a LTE signal out of the Verizon SIM, but more often than not the SIM Toolkit crashed and it'd require a reboot after which it usually wouldn't work anyway. Oddly enough the CDMA SIMs did work decently in the adapter(s) when used with a Verizon 2013 Moto X I have...*but* the CDMA 1X and EVDO connections never worked...just LTE. I have no clue if a Project Fi SIM would work with these but I'd be extremely skeptical...but eh who knows?
Hope this all helps - it's a freaking shame that Google didn't make the Nexus 6 (and now the 6P and 5X) dual-SIM - such a waste of an amazing LTE/GSM/CDMA radio to not offer a dual-SIM model IMO. Though I'm sure they may have their reasons? Too bad...I live in an area where it'd really help to have two cheap pre-paid plans with Verizon and T-Mo and then string them together with Google Voice. No dice though. Good luck!

Would be great if you do a Video showing how install the Adapters and your experiences
Sure - I'll try and throw something together.
Some additional info that I have found - for some really strange reason it seems that these adapters inhibit the reception of certain LTE bands. I've noticed that I can't pick up band 12 LTE with T-Mobile and band 13 LTE with Verizon when using one of these, no matter the ROM in use. But without the adapter I receive both bands perfectly. I do receive band 17 (AT&T) with the adapter which is bizarre as its also low-band just like 12 and 13. Also, bands 2 and 4 work well and I seem to remember band 5 at some point as well when I was in Michigan over the summer using AT&T towers with a Cricket SIM.
So anyway I'd say the use-case for this is if you have two GSM SIMs and don't mind hit-or-miss LTE reception...namely bands 2, 4, (5?) and 17 only though perhaps there are others.
In any case these adapters are temperamental and definitely seem to have their troubles. But they are also kind of neat and there are definitely cases where they'd be useful.

Hi,
Could you recommend an adapter to purchase from aliexpress? I am planning to switch over from Verizon to AT&T and now will have both my lines on AT&T's GSM network so I think I should be good (right?). Also, do the ones on AliExpress support dual active SIMs?
Thanks!
Hi! Honestly the adapters seem to mostly be the same (except for MagicSIM, which was horrible), even though they are sold by different sellers.
I know that I tried this one: http://www.aliexpress.com/item/For-...le-Standby-Flex-Cable-Ribbon/32333186041.html . Make sure you request the proper one though - they have both nano and micro-SIM sizes and you have to say which one you want.
I believe it worked fine and it's not very expensive so you can get a couple of them (I highly recommend buying a few of them as you'll probably destroy one or two of them before you get it to fit in there right). But in any case yes in my experience this scheme worked well with an AT&T SIM (mine was a Cricket SIM but should be the same thing really) and a T-Mobile SIM. Occasionally the SIM Toolkit would crash when changing SIMs and I'd have to reboot but it was pretty rare that that happened. Most of the time it was as simple as selecting the STK app and switching numbers. I should mention though that it took a few reboots initially to get things running correctly following initial installation...almost like everything had to "settle in."
WiFi calling and VOLTE also didn't seem to work with the adapter installed.
Additionally, the "LTE Engineering" app for T-Mobile's Nexus 6 build seems to crash the SIM adapter's firmware, so I think there's probably some data (maybe IMSI or some similar thing) which is getting lost in the adapter's chip? However, "LTE Discovery" and "Signal Check Pro" work just fine and don't cause any problems. Also, there's a chance that one's ROM might have an effect on it as well - it might take some experimentation to find the best combo of factors. Maybe some sort of build.prop edit might help too as I know there are some SIM/telephony items in there.
Finally, the "About Phone/SIM Status" menu in the phone's Settings seemed to always show the phone number that was in use when the phone was booted...but it didn't seem to be an issue as phone calls seemed to come in and work normally no matter what it said.
Good luck! Also I should mention that Amazon.com has these in case you're in the USA and want faster shipping - just pick one that'll fit an iPhone 5 and above and you should be fine. Let us all know how it goes!

Did you report these issues back to the AliExpress sellers (and, out of interest, do you recommend any specific sellers, and are the adapters themselves unbranded and without any model numbers?)

No I didn't report the issues except to MagicSIM, who was worthless even given two messages. As far as branding, there are small variations between the adapters physically but they are not branded as far as I can tell...and I've found they all pretty much work the same.
I do seem to notice some variation in how well the various Nexus 6 ROMs handle the STK, however...some seem to be more receptive than others to the adapter.

Very cool! Thanks for the video.
Just an update on the band 12 issue mentioned above - using QXDM I got band 12 back. It seems that the Nexus is doing some funny business with the NV 6828 item with the adapter installed and effectively squashing band 12 by using an odd decimal value. But, one can re-enable this permanently by adding back in an appropriate decimal in item 6828 per the instructions for adding LTE bands on Qualcomm chips (XDA has several threads on how to do this with QPST and QXDM). VoLTE still doesn't work and neither does WiFi calling (I *think* the ICCID is the culprit) but with full T-Mo band 2/4/12 LTE support I'm a happy camper!

So, I gave my American girlfriend a Nexus One (because Im a nice boyfriend) and it worked fine for her while she was studying in Europe with a SIM Card from Verizon. However, she has sadly now returned to the US and it apparently has stopped working, obviously because of the CDMA network.
So, just wondering if there is any way of using the Nexus One on Verizon in the US at all? She has a SIM Card as I said..
Thanks
Nope, fraid not.
Sad. Not even on 2G-only?
Nope, the radios / hardware are completely different.
GSM and CDMA are two completely different technologies which can not mix.
the best thing to do would be to sell it (if it's in good condition it should bring close to $500.00) and then buy an Incredible.
Or, switch her to AT&T or T-Mobile. Keep in mind that the N1 you purchased will get 3g on T-mobile or AT&T, but not both, depending on which one you purchased. It will get Edge on either network.
ASUS has just announced that it’s bringing the affordable ZenFone 2 Laser to the United States starting today. First announced back in early August 2015, this new device features similar specs to those of the ZenFone 2 proper, and comes with a few additional features.
It sports a 5.5-inch IPS LCD display with 1920 x 1080 resolution and Gorilla Glass 4, an octa-core Qualcomm Snapdragon 615 processor, 16 or 32GB of on-board storage, microSD expansion up to 128GB and a removable 3000mAh battery. Unlike the ZenFone 2 which features different amounts of RAM for each storage variant, the ZenFone 2 Laser comes with 3GB of RAM no matter which variant you choose. It also features a 5MP front-facing camera and a 13MP rear camera with laser autofocus. There’s no quick charging capabilities on this new device, and both of its Micro SIM card slots now support 4G LTE connectivity.
The U.S. variant of the ZenFone 2 Laser with 16GB of storage will be available starting today from the ASUS Store, Amazon, Newegg and B&H for $199, with the 32GB model going for $249.
Model 551KL. The international version of zenfone2 laser is model 550KL, which has 720p screen.
The octacore snap dragon makes this very tempting but no fast charge... Home on asus
Love the dual active dual LTE on both sims.. That is what a true dual sim phone is about. Does it have NFC?
No quick charge though as the previous poster stated. Like the processor is a Qualcomm, but the 600 series..???
Looked for it on Asus store and Amazon not available..... ???????
It looks like LTE is not dual-active. "Note
IMPORTANT: Both micro SIM card slots support 3G
WCDMA/ 4G LTE network band. But only one micro
SIM card can connect to 3G WCDMA/ 4G LTE service
at a time."
Also no LTE band 12 if you're on Tmo in the US

Any dual sim phone that has LTE on both sims can only access LTE data one sim at a time. But I get what you are saying, does this also mean they software blocked it to only get 4G on one sim at a time even with voice/text? If so that is a very odd and strange thing to do.
What I noticed in the specs though it says in their "brochure" that it is dual active dual sim LTE
but when you read the specs it says secondary sim : 2G/3G so which is it? Is it up to 4G LTE on both sims or not.
Dual micro-SIM
- Primary SIM - 2G/3G/4G
- Secondary SIM - 2G/3G
This will still work on Tmobile. I have a zenfone 2 and it connects to Tmobile either through bands 2 or 4.

Both sims support LTE. LTE data connectivity is switchable via the settings panel.

Very confused because another Asus rep on your own website stated that only 1 sim can run LTE which is a contradiction to what you are saying in your advertisement and what you are saying in your post as both sims run LTE. He said the following:
"Hey there – great question! The specs do say 2G/3G for the 2nd SIM because when both SIMs are being used, and the 1st SIM is used for LTE, hardware limitations set the 2nd SIM to only 3G – meaning LTE can’t run concurrently. "
I'm not understanding how this would be a hardware issue since dual active runs with 2 separate modems, therefore LTE should be available for voice/text on both sims at all times. Data however can only be on 1 sim at a time. But he is saying only 1 sim can operate as LTE and the other is 2/3G for voice/text. This seems more like a firmware issue that is blocking 4G LTE on the other sim not a hardware issue.
I'm very much looking at this phone to ditch my Zenfone 2 due to it's poor performance with the sim2 being on 2G. So would really like to have some clarification on this.
Also noticed no quick charge and no NFC on this model. I can possibly understand the quick charge, but really no NFC. NFC cost so very little anymore, I am not really seeing a reason for leaving this out. Just raise the price of the phone the $1.00 it cost.
It seems Asus almost gets there but then either leaves things out or uses bad hardware under the guise of "pricing". Putting a quick charge and NFC would have raised the phone pricing minimal and I would gladly pay another $20-30 for this. Additionally since you are coming out with this the other rep wouldn't state whether or not it would get an upgrade to M when released. You guys really need to do much much better in this area.

LTE is data only, and as this is an unlocked device, it is not compatible with TMO/AT&T VoLTE. Therefore, all calls/texts will ride on 2G EDGE or 3G HSPA+ networks no matter what. So no point in having dual active LTE, as it just serves to eat up more battery life.
Most other phones tend to have 1 slot that can do 2G/3G/4G and a second slot for 2G/3G only, which means if you want to use SIM2 on 4G, you have to power off the phone and switch the SIM cards around physically. On the ZE551KL, both slots are 2G/3G/4G compatible, and 2G/3G remains active on both at all times, while the 4G data connection is switchable via Android software. No need to turn off and move SIMs around to change which one you want to use for your data connection.
Whenever an application starts a data session (opening a web browser, email auto-sync, etc), the application asks Android for details regarding the connection. Since this is a dual-SIM device, you can select which SIM card you want the data connection to occur on in the dual-SIM settings. If there was no option, Android might randomly select a SIM that has a small data plan and eat up your data usage.
Sucks that there's no Band 12, but all the other radio decisions they've made sound right.

I'm not sure what having an unlocked phone has anything to do with VoLTE, whether the phone is locked or unlocked it can still be capable of VoLTE and there are plenty of unlocked phones out there that are. Eventually all phones will have to be VoLTE capable whether they want to or not, locked or unlocked.
In order to use TMobile's band 12 the phone must be VoLTE and E911 enabled certified by TMobile. TMobile issued a release on the already back in the summer. This phone will still work the TMobile system just fine as I'm using the Zenfone on both AT&T and TMobile and never had an issue hitting TMobile at all as it has the other bands TMobile uses.
I'm also aware as I stated above in my previous post that the phone can only use 1 sim at a time for data, however there are already dual sim phones that do not downgrade the second sim to 2/3G for voice/text it keeps it at 4G LTE with very little noticeable battery loss at all. Those phones and I had a Siswoo, was the same exact way in the OS that you tell it which sim you wish to use for data, this is not something new and has been around for quite some time. A lot of battery loss as to do with how well a company keeps up their firmware and OS on the phone to make sure the patches are done. To say nothing of how the actual end user uses the device itself.
The problem with downgrading the second sim to 2G would amount to the same issue I'm running into now with the Zenfone, it's completely useless as a dual sim phone as 2G is being shut down.
Thank you for your response but it still doesn't answer any of the conflicting responses from Asus.

Unlocked devices typically do not go through carrier VoLTE certification, the exception being the Nexus 6 that was offered by carriers directly (and Apple devices but that's an entirely different beast), which is why it has Band 12 enabled. The new set of Nexus' and the Moto X Pure, which are not sold by carriers, have not gone through carrier VoLTE certification yet, so despite their hardware supporting Band 12, it's currently disabled. However, VoLTE is not a requirement yet, as no networks are planning on shutting down both their 2G and 3G signals anytime soon. Considering this phone will probably never be certified for VoLTE by AT&T/TMO (none of ASUS' other US devices have VoLTE certifications), there is no reason for both SIM slots to have 4G access at the same time. Since both slots support simultaneous 2G/3G, when AT&T/TMO get around to shutting down their 2G networks, the second SIM will continue to function normally and do calls/texts over the 3G network.
I don't know if only 1 SIM being able to access LTE is a hardware or software issue/limitation, but since carriers won't VoLTE certify it, it's a non-issue. The only difference is that MMS on the second SIM might take a second longer to download over 3G vs 4G.

TMobile is the only carrier I think requiring certification, AT&T doesn't require anything. If your phone is equipped with VoLTE all you have to do is turn it on inside your phone with AT&T, TMobile requires you to call them and have it added to your account. Either way a phone still could be VoLTE whether unlocked or locked. certified or uncertified. AT&T rolled out VoLTE 2 years ago and TMobile is still in the beginning stages of a rollout. You're comparing Walmart with Macy's here, which is one of the reasons I ditched TMobile years ago. So I really don't care what TMobile does or doesn't do since they are not my main provider, AT&T is, so the fact band 12 isn't there has zero affect on my use. Regardless VoLTE has zero bearing on the what Asus is doing with the 2 sim modems in this phone. Since a dual active phone has 2 modems, my guess it is a software issue not a hardware issue.
AT&T has already started shutting down 2G in different areas and has stated by the end of 2016 all 2G will be shut down across the U.S. I'm in Florida and 2G is already down in certain areas. So yes, they have started shutting down 2G already. In fact my other sim from Three UK doesn't even offer 2G signal when in the UK, they don't have it at all on their spectrum.
Once again though, I still have conflicting information from 2 different Asus reps and nothing is being stated by them as to why and which one is the correct one.
This highlights the poor performance SIM 2 issue I went through on the ZF2 because of the 2G slot. It proved out because I have a new dual SIM phone now that gets LTE in both slots. I went through a terrible time unable to get calls in my house on the ZF2's second SIM. I'm able to on my new phone. I thought I was going to have issues at first, but my reception and SIM 2 availability have been consistent now. I can make and receive calls in my house just fine. I had minor issues at first, and it's fine now. My phone is provisioned to my new phone with my carrier on both slots. So that's what Asus needs to guarantee it can provide in that second slot; call reception that works! Too late for me. I found another product.

Exactly Babsk. 2 days now and still no response as to what is the correct information from Asus. The rep on their own forum said he didn't know if an update to M would even be available, they're still working Lollipop. Really? Still working on Lollipop 5.0. I wish I could get that phone you got, but not enough bands for me are turned on.

floridaman: That's truly a shame. I had to research the bands thing too. I have AT&T and fortunately the missing LTE Band 5 is not a concern. My area is using Band 17 all the time and the Pure XL picks it up just fine. I did an LTE band check before I got this phone and then figured I would also test it after purchase. My speed tests show I get LTE and my display says it too.
I hope you can get an answer from Asus. It would be great if the Laser could work out for you.

I noticed that as well in the specs on Qualcomm website's that this processor does have quickcharge. It's becoming clear that Asus goes in and firmware blocks things, for what reason is anyones guess.
If this phone had fast charge I would buy it and keep my zen2 as a backup
I'm looking into buying this since my ZE551ML has broken LCD. But, I'm confused with what the CS told me and what is advertised. CS told me that sim2 is only 2G/3G and not 2G/3G/4G as advertised.
Also, no root yet.

Hi Everyone,
I've been reading the reviews and specs for the MI5 Pro and am considering purchasing one. GSM/CDMA support, 128Gb Storage, etc. sounds great to me.
My plan is to have something with an unlocked BL so I can root, TWRP, and AOSP it just the way I want it.
Before I do how much of a pain will it be to getting working on Verizon's 4G/LTE networks? If I understand what I am reading correctly it supports all the frequency bands on Big Red. Any thoughts? Comments and suggestions are requested on this.
Thanks in Advance
I should also add this is not for the BYOD (Bring Your Own Device) program. I have a monthly plan and am up for a new device but don't want what they offer.
I highly doubt you'll be able to get it to work on Verizon. Even unlocking GSM bands is a pain.

VZW is CDMA. The specs say it supports all the needed bands I just don't know if they are "active" out of the box.

I don't specifically know about verizon, but our local CDMA carriers do work with the Mi5.
Cdma carriers the us only allows approved devices.
No hope.

You can be the guniea pig and try it out but your chances of getting it to work on Verizon are slim to none.

The more I research this the more dim the results look. It seems that the problem with bringing it to a CDMA network is lack of 4G functionality. Definitely a deal breaker for sure......
Verizon only allows approved devices on their network (read: their branded devices). So there's pretty much no chance of your Mi5 (an unapproved, semi-compatible, and untested device as far as they are concerned) getting on the network, as your MEID needs to be in their system for you to connect to their network.
Stick with an actual GSM carrier.

I knew that was how they were in the past but I thought maybe they loosened up on it. They now have a Bring Your Own Device program. Still doesn't get past getting 4G working flawlessly on CDMA.
I need to look deeper at GSM carriers in the US. Coverage in my area is important for work.
I just saw you message and it is a bit late, but I have the Mi5 and use it on Verizon. It is only 3G on that. I can also use both my Verizon Sim card and my AT&T sim at the same time and have two carriers with two different numbers on the same phone. I had to do nothing to get it to work on Verizon other than pop in the sim card. I hope this helps.
Thanks DFSPCC, I was wondering the same thing and having it listed to work with VZN in the US on willmyphonework.net up to 3G speeds, which is fine by me. Considering the low price at the moment for the Mi5, I think is a great option.
Never to late
I'm considering on getting this phone... 5.7 inch with OK specs to work with Verizon only thing is you said 3g but that's OK its just to play and test hopefully I can root it... Don't knkw if they have any Roms for it..... Ive been HTC for over 10 yrs and they have let me down been waiting for a 5.7 or bigger... The max was nice but bad specs realy slow so.... I was going to do the s8 plus but now I see the U12 coming soon. But i don't know if Verizon will carry it... They don't carry the U11 don't know why.... What do you think? And thanks again for your time and help god bless....

I know generally that most unlocked Chineese phones are not Verizon compatible. But, both the OnePlus 6t and 7 pro are even though they are LTE only so I figured there may be a possibility and was curious if anyone actually attempted it.
This seems like the best phone on the market right now, it's almost $200 cheaper than the next snapdragon 855 phone in the US.

Works great on AT&T Prepaid Unlimited, typically for CDMA carriers you need to buy they're approved phones.
I'm actually on Verizon unlimited and had the same questions for them.
I installed my sim card from my previous phone LG v20. And it seems it's using the provisioning from it. All the network info was there. But couldn't seem to get data. So I used shortcut master lite and went to the telephoney part of network settings and had to play with the network settings. Got it to work really well by downloading a network settings app and playing with the band info. It's pretty straight forward and easy to use.
By the way Verizon has no idea what kind of phone I have and it says it's rooted. But it's not. Cloud works great, my Verizon, message+ and anything I throw at it from the Verizon apps. Tech support said that as long as im using my existing sim and have done whatever I did to make it work. Keep doing it. But they have no idea if they are going to setup services and get the info anytime soon.
So I got just what I always wanted.
A nice phone that they can't track or get into it unless I allow them. Perfect
This phone works fine on Verizon, I currently have both the phone and Verizon service. VOLTE works and everything, just no wifi calling
Wow! You all are using the North American Nubia Red Magic 3?
I'm usually on T-Mobile most of the year but during the summer I need Verizon where I go so I didn't consider the RM3. I usually use total wireless or StraightTalk and I've had good luck with slapping their SIM cards into different phones without an issue.
So if you all can tell me the tricks, if any, and which model (US or international) I'll pick one up — sub $500 for S855 and big AMOLED screen!

And what about band 13 on Verizon? Isn't that the main band for them?

No band 13, but Verizon also uses bands 4 and 5 which this phone supports. I actually believe band 4 is their main band. I didn't have to do anything but put my SIM card in. Although in the past when I had a OnePlus 6T, I had Verizon provision my line to be LTE only. Don't know if that step is needed for this phone, as it supports CDMA. I'm using the North American version bought directly from Red Magic.

Thanks for the info. Band 13 (700MHz) is Verizon's main band due to its penetration and distance, according to online info, but you are also correct — 2, 4, along with 5 and 66 all work on Verizon. If they put 71 and 13 in this thing it would have everything. So I should be able to get something in most areas.
Good to know I just need to put the SIM in. I can always activate on my old Moto X Pure.
Thanks again!

Please oh knowledgeable one, bestow upon me the settings you used to get the phone to work on Verizon. I popped my SIM in to the phone when i first got it and ZERO issues for weeks. Then recently all the sudden I no longer had any service whatsoever. No matter how much I tried to play with the settings, nothing seems to work. What appp did you use for the network settings to play with the band info? Really don't want to change carriers right now.
Please and thanks in advance :silly:

Well it was easy, phone off , installed the sim card and poof service for about 2 hours and then I had to keep toggling the airplane mode. Until I remembered when my LG V20 stopped getting signal because I had it rooted. Verizon kept trying to kick it off because they don't want rooted phones on there. And also there software constantly tries to update the phone to remove root on you.
Anyways, I m sure you know this part of Verizon. There are many variations of it. But network settings App. All pretty much show the same menu. But LTE only is what you select. And you will constantly have to go back into it and enable the data. The menu looks like this hopefully I can post it but choose LTE only.

So it basically doesn't work because you have to jump through hoops to make it kinda work?
I remember when I sold my Pixel XL, the guy was able to use it right away on Verizon with his sim card.
Did Verizon add more measures to keep people away with unauthorized phones?

Well all I really know is that they say that they just don't have any info about the phone. It has all the bands that work. Except band 13. I haven't rooted it because there still isn't a functional root for it. That setting in the pic I downloaded, theres a switch that says immediate. That's changes to disabled because of the doze function. It's solely for data. I keep mine on lte only. And just have to change it from disabled to immediate. It's kinda a pain in the rear. But. Its a functioning phone on Verizon service that they say doesn't support it. No Verizon apps except cloud and My Verizon. With limited access. It's great as far as I'm concerned. Biggest problem with Verizon. Is Verizon.
But as soon as a functioning root is available and im comfortable I'll root it and enable band 13. I'm pretty sure it's there. Just Verizon won't pay to get the access to the phones. So there's that.
One more thing the OnePlus 7 pro works on Verizon with some GSM function. There support just won't try to do it on the RM3. Other option is you have a second Sim slot. Get you another sim card and that takes care of emergency stuff.
Guess I'll be buying the best gaming phone ever made, the Red Magic 5G next! Sorry Verizon, it's time to move on. Or you can support this baby and make a lot of money.
My old Iphone SE (1st gen) gave out after nearly 6 years of solid service. So I'm finally looking for a new phone and I absolutely cannot stand how large phones have gotten. I don't want a screen that's literally half a foot corner to corner. The XZ1C is the perfect size and shape but there's one problem, it's GSM. I know that CDMA and GSM have died out completely and everything is LTE and up. After looking, I see that the XZ1C supports both voLTE and B13 for Verizon, meaning it should theoretically work on their network as a normal phone as nothing there needs CDMA anymore. When I asked the Verizon support (stupid move, I know) they told me it wouldn't work because it's GSM and that I would need to look at their website to find a phone. I know that they're more worried about lining their pockets than actually helping.
Has anyone managed to get an XZ1C working as a normal phone on Verizon's US network now that the GSM vs. CDMA debacle has finally died out? If so, how difficult was it to get working? I'm almost certain I'll need to get on support with Verizon to get the phone whitelisted but I just want to make sure I don't buy one only to find out that there's some hardware incompatibility (I do know I would need the G8441 model). All the threads I can find on it are from ~2017 when the phone first launched.
Any help would be much appreciated!
Not all LTE is the same, there are still different bands for different providers.
From memory, I used frequency check (or similar, https://www.frequencycheck.com) to look up compatability with the various providers. At the time, it didn't look like Verizon would support it, but you should double check my work, since it may also have changed.
You could so try a SIM if you have one (both the phone and the card). I borrowed a friend's at one point and had little success, but again, it was a while back, and I didn't tyres to get it whitelisted.
I hope that helps. Let us know how you fare.

Checked the freq and it showed the same as the website I use (Kimovil). Same bands are present which is shown to be all except one Verizon band. The main one (at least according to the workers on the Verizon support forums) is B13 which is the main band that carries calls and texts now.
Ah, maybe their primary band has changed, then.
I think it was the opposite last time I looked.
