Question Samsung ultra 21 Global or US version to purchase for rooting and AT - Samsung Galaxy S21 Ultra

If I were to buy a Samsung 21 global version for rooting will it work with At&t network out of the box or should I just go for the US version and pay the money to get it unlocked if it is still possible. Also, does any one have any good links to get the global SM-G988b version of phone?
Edit: Accidentally hit enter when editing title.

AT&T has this whole whitelisting of the devices on their network for all features (like WiFi calling) to work. Better to buy a US unlocked variant. In the past, it has been possible to root Samsung US flagship versions.

Ah ok. I never cared about things like WIFI calling. I just wanted to still be able to make phone calls and get internet. Thanks for the info though. I still prefer the Global one if it works in the USA and so just wnateed to know if it will work in the usa.

If you look at the bands, the Exynos S22 is lacking bands 260, 261 (5G mmwave bands) and bands 14,29,30,66 so the coverage won't be good

I have the 998b/ds i just purchased . When it came the card in the package said it wouldnt work on cricket. I went to cricket and called. Ran my imei and was told everything would work fine. Cricket if course is att.
I will be calling today and asking why my coverage is so horrible. I wouldnt have opened the phone if they had told me everything would work.
I am experiencing horrible reception at my home, which is in the mountains. My s20 ultra worked fine and got 5 g up here.
I will report back what i find out. As for now i am disappointed i am not getting 5g at all.

Ok thanks. So looks like USA Version is my best bet.

N950N Note 8 256GB working on at&t

SO I picked up a 256GB emperor edition from Korea. It is Confirmed to have every single LTE band that AT&T uses. I put my sim in and only get 3G not 4G. Called at&t and they said they need to re-appropriate the IMEI for the USA as it comes up as a 2g/3g phone because the SKoren SK telecom IMEI assigned to the phone is different in the USA. IS that True? Anyone know how and if I can get the Phone to work on 4G LTE on at&t or do I have to hope they get it right? I paid $1400 for this phone I don't want to use a 64GB version I have been waiting to have 500+ GB on a phone for so long.. Any TIps? Hints? Recommendations?
EDIT: for those reading this thread for the first time. As of 10/9/17 I was able to get good LTE speeds as well as WIFI calling and Video Calling on my N950N note 8 Korean Exynos model. In a nutshell here is what I did to make it work.
Flash nemesis n950F rom to my phone.
Flash AT&T CSC to the phone using the CSC tool and you do have to modify one line (user RED FLAME) has this in the CSC thread.
Call at&t and give them the IMEI of a VOLTE wifi calling/video calling capable cellphone (I used my wifes S8+ - and yes you can DOUBLE USE IMEI on the same account)
I also did one other thing - Check page 14 for that information.
I just wanted to give a synopsis of this thread so new N950N and at&t owners don't feel like they are wasting their time searching XDA and google. I only wish other people did this when their problem is solved so people can easily see they are not in the wrong place and don't have to read tons of pages of stuff.

Hi.
There is a thread somewhere here they were talking about similar problems.
What you where told is essentially correct. Though they also said that they needed a new sim card, too.
Hope this helps. Still waiting for my Note 8.
Too bad those devices do not have the CDMA bands...
I have the same model and same problem but with softbank, though softbank has been less helpful.. i read someone flashing a different csc (if its the right one) will "unblock" the phone? Would any exymos model csc work?
My roaming menu is also greyed out... not sure if that is related.
I think you just need to give them the IMEI and have them set it up for LTE in their system, since they don't by default allow LTE on bring your own devices.
Did you change the apn? I have the same phone on tmobile and i changed the apn to the tmobile apn and i have no problems with the phone.

Just a quick comment - I think you mis-spoke. ATT Does allow LTE on Bring your own devices. I have been using G955F variants for the last 4 years and never had to do anything other than put the SIM card in for it to work. HOwever, LTE Enhanced Services are not available on Bring your own Devices. This includes HD Calling, Wifi Calling and Video Calling. BUT, LTE will work.
I don't know anything about the Korean Model so I hope the OP is able to get things straightened out - but other variants have always worked on ATT - including TMOBILE PHONES and international variants as well.

That's probably what I meant. I haven't been an AT&T customer for many years, and have been with T-mobile for all my smart phone career, and they don't require any special setup on their end for VoLTE, Wi-Fi calling, etc as I can confirm with my Korean Note 8. After somewhat jankily switching CSCs with a modified script that was originally made for S8 and 8+ phones I definitely have VoLTE and probably have Wi-Fi calling working without any communication to T-mobile.
Waiting on at&t now.. to see what happens.. SPEC for SPEC this phone is exactly the same as an at&t phone. It has every single band, not missing a single one. If you put the specs side by side there is ZERO difference. I changed the APN - there are 3 at&t choices. One gives me 3G the other 2 do not work. SO waiting on at&t to re-appropriate the IMEI to register as a note 8 on their network. I had not idea it was going to be this much of a pain in the arse. I was told by a few sellers, pop in your sim and your good to go. I did need a new sim since my note 4 sim did not fit in the note 8, so They gave me a new sim. I put the sim (using an adapter) back into my Note 4 until they change over the IMEI and the new sim works just fine on the note 4 - all my video calling, wifi calling and tethering work fine. So hoping I do not need to return this phone and use a 64GB model. I wish samsung would just release the 256 here on at&t like apple is doing with the iphone X. I would pay $1200 for it no problem. (and since the iphone X is $1149 with 256gb - I am sure samsung would do $999 or $1099 to undercut apple. But Samsung is going to epic fail and never give the US customers what they want.
Hi there, I would also like to have the Emperor's edition, and use it in Canada (Bell) and USA (T-Mobile or AT&T). Is N950N the correct model number for this edition? Does it come with dual sim? Thanks! So far I found an Ebay seller from Hong Kong with F950FD which looks to be 256GB Duos - I'm wondering what the difference is with N950N and whether I will have an issue with region lock?
Thanks for any comments...

No, I was using it on a HTC10 and previously on a Note 4...
Totally DIsappointed... No way I am keeping this $1300 phone for how crappy it is on At&T.
They Finally Updated the IMEI so that is shows up as a next gen smartphone on at&t network and I get an LTE logo. I set my own ACCESS POINT as well as used all 3 that showed up automatically. ATT Phone, ATT NEXTGENPHONE and ATT UTDATA (Nextgen) + I did what was recommended on att.com for bringing over a phone that might not get the access point which was the same settings as ATT Phone - all of them gave me LTE on my bar and showed AT&T as the network. Every single LTE Band on this phone is the same as the official ATT note 8. Yet on my speed test I couldn't get better than 4MB/s down and 1.56MB/s up, my note 4 (pop the sim card back in there) even with 1 Bar on my phone I get 42MB/s download and like 10MB/s Upload.
IT is too late to call at&t tonight but I am extremely disappointed. I have wanted a phone with 256GB of memory for like 2 years now, and to have MicroSD expansion for just MUSIC (NOTHING ELSE).
If At&t can't get this note 8 to perform exactly like a at&t version would, then I either going back to my Note 4 or Perhaps the US Samsung unlocked version (which I already have but is not opened as I hoped to sell it and make a few hundred on it to make up for the $1300 I spent on this Emperor Edition.
Any advice?
Anyone want to buy it.. I paid $1299.99 Shipped from NK. Instead of returning it - if anyone wants to buy it, id do the same thing $1299.99 shipped anywhere in US or Canada. Perhaps it will work better on another network...

tl;dr - Under Settings->Connections->More Settings there's an option titled Reset Network Settings and, i had to use that on my Korean, Note Fan Edition to get LTE working.
more detail on how i got VoLTE and HD Voice working.... i grabbed an ATT (Snapdragon) S8+ CSC and manually applied to the FE. To get HDVoice and VoLTE working, i called ATT and told them i was going to use my (no-longer used/retired) ATT Samsung S7Active with my cell number. this step was a must to get VoLTE working. once they associated S7Active IMEI with my cell number, i rebooted the Note FE and VoLTE was active. i occasionally receive calls and the HD Voice icon appears on the dialer screen; i assume the other person is calling me via Wifi when i see the icon. Video calling and Wifi calling haven't worked for me on none of my international devices. once i got my UK note 8, i applied the same CSC content (after rooting my device), i inserted the same ATT sim used in the Note FE, reset network settings and VoLTE and HD Voice (when receiving calls) still works.
I don't know about the Korean model, but here is how you get Volte on ATT on the Note 8 F model. https://forum.xda-developers.com/showpost.php?p=73851525&postcount=308 After you slightly modify the zip and flash this, you must call ATT and give the friendly customer service person the IMEI of a phone purchased from ATT directly that is roughly equivalent and had Volte and wifi calling features. I used an old S7. ATT will NOT accept an IMEI of any phone not sold by ATT. Once they put it into their system, reboot your Note 8 and whala - wifi calling and Volte work perfectly.

Kind of a NOOB when it comes to all this. I haven't flashed or done any phone hacking in a few years (my s4 was the last phone I really played with).
SO I downloaded the CSC Selection V1.2.1 on Android Filehost
I honestly do not know what to do from here.
Thanks.

note 9 verizon vs note 9 tmobile

I have an up to date verizon note 9 although still paying for it I had it on their service for over 6 months so legally allowed to use on another service currently using it on cricket with no issues other than no VOlte which I've never had with cricket no matter what phone because I won't use the phones they have because I don't like them but that's another story....Since I can't get volte on my Verizon model note 9 that's fully updated for US I was wanting to switch to tmobile...I was set up with a sim card on their magenta plus plan worked great till I got to my home which is in a more rural area but did show verified coverage at driveway on their map I had no signal so I went to settings searched for mobile networks found tmobile listed registered and it connected like 2 bars LTE but within min lost service did it again lost service again while I had lte I was able to call and use data...so my question is could this be me using a verizon phone for it not latching on by itself or holding the signal I know note 9 has the 600mhz band but was wandering if I went ahead and got a tmobile phone if it would actually latch on and hold the signal that Verizon's addons and changing is playing well with tmobile...UNLESS someone can tell me how to get VOlte on cricket with this note 9 then I wouldn't need tmobile then 3g calling has went to crap over a year....thankyou for any input

All N960U and N960U1 devices are EXACTLY the same. The only difference between the devices is software.
Flash the software for the carrier your running including the Userdata for you Note 9. It should work for all features especially on T-Mobile. T-Movile fully allows unlocked devices on their network whereas Verizon doesn't. I'm pretty sure at&t is like Verizon through when it comes to unlocked devices, and they own cricket so that rule probably trickles down to them as well.
You can get all carrier version of software for your Note 9 on samfirm or sammobile

But my question would be would my phone latch on to tmobile towers using tmobile firmware better than my current state using verizon firmware I'm excluding wifi calling and volte just trying to determine if I would have a difference in service availability picking up towers and holding them with stronger lte signal or if it's just poor coverage both ways and will be no different than you for your advice as well

You will not have a difference in coverage. T-Mobile did the same thing with where I live and listed it on their map as being fully covered. I barely get LTE at my house or anywhere in my neighborhood.

You will never know until you try it, so why not try it and find out? Make it an SM-N960U1. Debloated and ready to go with any sim you install. Flash the unbranded firmware that can work on any of the US providers. That's what I have, and when I loaded a T-Mobile sim, I got VoLTE and wifi calling. I've run a lot of custom firmwares in the past, but this is the best phone and firmware combo I've ever had. And it's pure stock.
Also, this stock One UI with dark mode is very slick. VERY! No Substratum, no themes, no fuss. Just clean and black.

His goal is better service reception.
Only the carrier can fix that by actually providing the coverage they put on their maps.

Lots of people have reported better or worse quality service, all other things equal except for firmware/software: different radios enabled/disabled; different optimizations. I just read another thread where someone got better tmobile reception at his house after flashing tmobile software over US unlocked software. There are more variables than just the carrier side of things.

Thankyou then that kinda answers my question that although phones are equal between verizon version and unlocked internally and firmware being the difference that using a tmobile phone with their firmware I'd stand the best chance of service and since my area uses extended range area I would probably have a better experience than on my note 9 verizon...thankyou again

Yes. I think it may make no difference at all, or it might (much to gain, but nothing to lose), but most of the evidence in these forums, when it comes to connection quality, is extremely variable and anecdotal. Nobody can know an answer to this kind of question, unless they test it out for themselves. Good luck!

Wifi calling and voLTE on Att only

Wanted to ask if anyone with a USA model rog 2 tried att Sim card and did it work with att? We already know t-mobile doesn't list those options. This way we can all go search for phones that will suit our needs.
My US model will be delivered either Saturday or Monday and I use AT&T. Will post my results then.
I just talked to support again, and they said no VoLTE or VoWifi on Tmobile, Verizon, or AT&T, or any American carrier. They have no plans to enable it. The suggestion was that I leave them a complaint, so I did so via their form on Asus.com as well as Facebook.
The problem is AT&T is shutting down their 3G service this year so if VoLTE isn't enabled we can't make voice calls.

As is TMobile, from what I understand. You should be able to make calls, but it will default to EDGE, IIRC.

Ok I just tried to confirm and got info they're not shutting down 3G just yet. We still have a few more years.
I guess that's good we'll still have calls but isn't good because there's no reason for VoLTE.
Thanks to ryououki for the offer, we will await your testing and we will be here if u need any help
I seriously don't understand a U.S model, yet no volte? That's just dumb. Wtf?
I can tell you right now it wont work, Its a sick phone but I'm sending it back because of this. Asus screwed up with no VoLTE, no VoWiFi, and only a 1080p screen IMO. Maybe next time they will get it right. I hope the OnePlus 7T and the 7T Pro has it... Crazy!
Just read this for T-Mobile:
Due to lack of VoLTE support you won't be able to place and receive calls including 911 calls in some buildings and some outdoor areas where 2G GSM and 3G HSPA+ signal (marketed by T-Mobile as "4G") is too weak or non-existent while LTE band 12 is available
Great info so far , just need someone to try it with att sim for confirmation.
So far we know,
Tmobile no go on volte or wifi call
Verizon works on data only no calls or txt just like rog one. Cdmaless option unclear at this moment .
Att no test yet
I have a US model on AT&T and can't get VoLTE yet.
I talked to AT&T support and they said there's no compatibility yet.
The IMEI doesn't come up in their system as a known device.
I have at&t and a USA version of the phone, I can confirm as well that the phone drops to 3g when making voice calls.
This is really really bad because at&t plans to shut down their 3g in 2021, that means no voice calls after that. Asus USA knowingly selling a $900 phone that cant make a call in 2 years is borderline fraudulent.

There has to be options somewhere we can atleast get VOLTE working. Yes root will be mandatory, but i am ok with that. I might order one from amazon. Whats the return policy for phones on amazon? Anyone know?
I believe there were reports that VoLTE was working on Tencent models?
We really need to look into making a custom rom for our phones for the US carriers.
Did you try dialer codes *#*#VOWIFI#*#* and *#*#VOLTE#*#*
How ridiculous. This is how you ruin a near perfect phone.

I did more research, it seems to be more on the AT&T side than on the Asus side of things. Barring a few well-know phones like the Pixel 3, most BYOD Android devices on AT&T in general don't get VoLTE, including unlocked versions of Samsung Galaxy devices that are not purchased through AT&T. It looks like AT&T does not enable VoLTE for device models with IMEIs that it does not recognize (i.e. doesn't have AT&T certified ROMs), because they are afraid of getting fined by FCC for non-E911 compliance which requires the carrier to certify E911 support on all handset/firmware when on VoLTE. My guess the Tencent models with VoLTE working are somehow whitelisted by AT&T ad-hoc or they are working on Non-U.S. carriers. So it is more of an AT&T problem than an Asus/ROM issue. (though there may be ROM hacks to ask the handset to force VoLTE even if AT&T doesn't advertise the capability during protocol handshake).
Since this is a much bigger issue than just the ROG II phone, hopefully they have a plan to white list all BYOD Android devices for VoLTE when they sunset 3G. Otherwise AT&T would stand to lose a good chunk of revenue from those who migrate over from other carriers with BYOD phones, say a Galaxy phone with a T-Mobile ROM. You simply can't even offer a BYOD plan if you don't have voice call working for most of the BYOD Android devices.

There has to be options somewhere we can atleast get VOLTE working. Yes root will be mandatory, but i am ok with that. I might order one from amazon. Whats the return policy for phones on amazon? Anyone know?

I'm pretty sure their return policy for phones is the same as all other goods. I bought and returned the original ROG phone last year through Amazon, considering doing the same with ROG II unless there's a breakthrough on providers and features with custom ROMS/etc.
Yea that's pretty dirty to whitelist the Tencent version but not the US model.

Verizon 20FE on Xfinity 5G?

I am planning to purchase an S20 FE direct from Samsung. I am on Xfinity Mobile (Verizon MVNO). Xfinity now offers 5G. I usually purchase unlocked phones but not sure if this will work.
1. If I want 5g will I need to purchase the Verizon model?
2. Will I be able to use the Verizon "variant" on Xfinity without ever activating on Verizon?
I asked Samsung, Xfinity and Verizon and no accurate or definitive response.
Xfinity:"You need to purchase your phone from us", I am currently using unlocked S9 Plus not purchased from them
Samsung: "Verizon phones only work on Verizon and will not work on any other carrier" (agent did not know what an MVNO was)
Verizon: "All Verizon phones are sim-unlocked but you cannot use a Verizon phone on Xfinity because it will be network locked"
Thank You in advance for helpful replies.
If I'm not mistaken when you try to purchase Verizon phone you will need to have account at Verizon ..it will ask to login to verify existing user ...a d must activate on Verizon ... I'm also thinking their version phone has different 5G capabilities not 100 % sure though View attachment 5105831

Ok, Thanks, I never got that far on shop.samsung or I would not have asked the question, seems kind of moot now.
I did understand that Verizon variant of S20FE is mmWave. That is what Xfinity Mobile uses for 5G (Verizon towers) and why I wanted Verizon variant.
Seems the bottom line is I can't buy the Verizon variant without a Verizon account and the unlocked variant is 4G only on Xfinity... kind of deflates the value for me.

You wanting the 5G for future proof? Right now 5G you would be lucky if you found a good spot ...I'm on Verizon passed on their version and went unlocked ..
Yes, that is good point and same conclusion I came too. I figured Sammy was going to give me $350 for my s9+ it so for around $350 out of pocket I could get a decent phone that would last me another 2 years. I wanted mmWave 5G for future proof but I think even Verizon will have to build out sub-6 network eventually if I read correctly. I just looked at Vzw 5G map and it is not "34 Cities" as they claim, it is more like a few neighborhoods each in 34 cities.

Question Xiaomi Mi 11 Global on Verizon?

Has anyone tried getting this bad boy to work on Verizon?

Yes. I tried. Lack of band 13 makes it a no go. Does not work at all.
Same here. I had to get a Mint Mobile sim for it. They use T-Mobile's Network and if you put the IMEI on T-Mobile's checker, it will say it isn't compatible but it is. Works fine on Mint except my house happens to be a T-Mobile dead zone. Oddly enough, customer service at Mint Mobile will also tell you that it's not compatible if you contact them about it. Kind of annoying, honestly

You can enable wifi calling and VOLTE thru T-Mobile via the secret dialer codes. Google it.
Thanks! This is very helpful. I'll look it into once I'm done flashing the Global rom. It came with EEA version on mine. Though, I've been hearing better things about the EEA variant so I might flash back after I test drive the Global one a bit
It should work on vzw, my mi 11 ultra CN rom is working right now and is sitting on band 2. I did notice though I had no signal until I disabled carrier check for volte thru the dialer with the hidden code and after I rebooted it worked on vzw. Just make sure your sim is activated in another phone first and you be good to go. Also Depending on where you live and availability of other bands your service will definitely not be the same but honestly in NJ and NYC I haven't noticed a difference yet.

Yeah, I think it's all band 13 where I live, more of a rural area. However, I will try to disable carrier check and see how it goes. Actually have a Verizon signal extender at my house but hotswapping the vzw sim resulted in no signal.
