volte works on the v40, but it's not as simple as that. If your carrier is so-and-so, they allow it with their phones, but not others. Some carriers allow it with bring-your-own device, some don't.
you don't say what variant your phone is other than405UA, that could be sprint, vzw, att, etc.
you don't say who your carrier is. How can anyone help you? There isn't some 'magic switch' somewhere

Well the first and most important thing you need to know is if the phone is 'Carrier Sim Locked'. In other words, if it is sim locked to AT&T, then the only way it will work with another carrier is if AT&T unlocks it for you.
IF the device is not 'carrier sim locked', then for you, because of where you are, would want to flash a kdz that has the 'bands' that your local carriers use.
If it is sim locked, don't flash a kdz rom to the device, because the software needed to unlock it is part of the ATT rom. If you flash over that, you'll lose that software and have no way to carrier sim unlock it.

So long as you think it's carrier unlocked, then follow this thread to cross-flash to a different rom.
keep in mind, your carrier has to also support volte and vowifi for it to work. Even though the phone may be perfectly capable of it, if the carrier doesn't support it, not gonna work.
cheers

I tried to flash my att branded v40 with his thread for a week. every kdz. Crossd error. I then tried 1.14 dev then got dll errors, and tried every common dll I could find. I think I need a higher patched dev, and some magic dll. but really don't know.
------
My original thought was to get a 6 dollar a month tmobile and get 4 lines gig of data each. Unfortunately, in Cleveland ohio, tmobile sucks compared with verizon and att, forget it outside the city off the highway, without band 71 600 mhz. My kids wouldn't take the phones and plan.
I also tried verizon, page plus, but they won't activate it, and saying not volte capable. with tmo, I was thinking data only. But on page plus, I want calling.

Does ATT know im using a Tilt?

OK so i bought an used att tilt from someone and did not notify ATT about it. I purchased a media Net unlimited plan for 15.00 a month (not for pda smart phones) i did this from a att authorized retailer. The guy who added media net for me is a friend and he said he wont make any changes because att thinks i have a razr v3xx and this way i do not have to pay 29.99 or whatever it is for media net for pda's.
Today i signed into my ATT account and under my devices it said att tilt.
I did not make any changes so how did my device change?
Does Media Net report back to att what phone is connecting to the network?
is there anyway to stop ATT from knowing what phone I am using?
I am aware that what I am doing is most likely a breach of contract and do not mind that fact.
Thank You,
KP
AT&T will always know what phone you are using since IMEI numbers are unique to every device.
As for the rest of your questions, hit up the forum search for the answers. (Hint: clicking this link will do the hard part for you.
The answer is yes, they do know. There is no way for you to trick them. You can however call and tell them you want the media net unlimited, because you are the customer. I did this on my blackjack II for a year. They told me it wouldn't work but I am not retarded, it is the exact same service, but people who own 500 dollar phones can afford to pay more. This is also why ATT has a special "email" plan that costs 10 dollars a month, which is funny, because email uses the normal data to work, its not like your buying an email address from ATT. They screw you over and you just need to tell them how it is, "GIVE ME THE MEDIA NET PLAN !"
It's their network, you cannot hide from them.

That probably happened because you needed a SIM update and your jigging with the phone caused it to happen.
Also, AT&T always knows, sometimes in business it's cheaper to "ignore" a problem, than to pursue stopping it.
If you are using $15 Media Net service plan you may want to take a look at this thread which offers changes all your data connections to solely use media net.

Very nice indeed my friend.
*update*
just signed onto my account right now and my phone device has been changed back to ATT Tilt...
so how often do they check IMEIs that are on the network or is there any way to stop your phone from broadcasting that info to their network?
if i call ATT and just tell them I am using a MotoRazr will it stick as a razr or as soon as i change my sim into my tilt it will change from razr to tilt because most other threads are reccomending to call them but no one has mentioned if it sticks or after a while your IMEI is recognized as another phone.
i think they finally stoppd with the false data plan promos.. i don't see them available anymore.. they probably pissed enough ppl off
Might I make a suggestion?
Quit trying to rip of your service provider. Soon the will fire you as a customer, then what will you do?
Not so with unlocked touch dual
I just bought an unlocked touch dual and my ATT account still shows the old Razr phone. Also, I did buy the pda plan as work is paying and I'm using exchange sync.
Is an unlocked non-att branded phone not showing up in their system?

Congrats, you made a Mod...have fun...
MOD EDIT: I will, Thank you
i'll be a...ha hah..
My understanding is that AT&T has a database with the IMEI #'s for all of the AT&T branded devices, and it checks your device everytime it connects. So the only way to get around it is to buy a 3rd party device (not AT&T branded). But if you do that, you run the risk of MMS not working correctly (showing up as a postage stamp sized image).
Yeah this crappy fact of the matter is that AT&T's mobile network is a private infrastructure. The government doesn't require that they let anyone on. Like they do with Landline infrastructure. So basically AT&T can do what the want, within reason.
AT&T allows unlocked or non-AT&T branded GSM phones on their network because, if the phone works, why not make money off of it?They just won't guarantee a thing. In fact they don't guarantee a thing to AT&T branded devices.
Is it fair to the consumer, maybe not. But that's how it is.
I've had some phones not show up wrong or not at all. I think all the newer handsets ID themselves.
If the phone was originally sold by AT&T (Locked) the the network knows what it is. However if the phone is unlocked (bought from manufacture) then AT&T has no idea what device you are using. It will just show up in the database as "Unknown GSM Device"

[Video] Verizon On my nexus 5

Took the sim out of my Verizon s4 and was determined to get this N5 up and running on big red.
I have full lte after a lot of tweaks that I probably shouldn't post right now do to what it could possibly do to a phone.
If you are a Dev and think you can do more with this let me know and I'll get you to where I'm at. I'm just a themer with basic dev knowledge. As you can see there is no signal to text or call. I've had bars a few times but that's it. As you see I'm on L. I had to crop one screen on phone because of upload size restrictions.

Looks interesting so far. I can't recall whether this device supports VZW's frequencies. If not, calls may never work.
I'll assume you modified the APN for VZW. Did you try modifying the radio?
If you post what you did to get data working, other members may have some additional suggestions to get you moving again.
its been gotten to, the lte connecting. but it's the calling ability that cant be done. i dont remember what all really came about, but i do remember thst the calling ability is the real issue. the nexus 5 doesnt have the ability to make phonecalls via lte. if you search the forums here, maybe you can find the thread.

Calls won't work for two reasons 1) I don't think Verizon uses VoLTE yet, and 2) calls still use 1x, just like Sprint, and you have to have the MEID (IMEI minus last digit I believe) in Verizon's database. Technically it should work on Page Plus and I think I saw a thread here on how to flash it for PP. I'm kind of surprised Verizon LTE works as most of the bands for Verizon's LTE don't coincide with the N5 IIRC. I could be wrong about that though. Also it's probably like any other GSM carrier, once you activate the SIM card in a carrier based phone, you can stick it in another phone and it should just activate. The only reason you have to change IMEIs is for the EVDO/1x backwards compatibility.

Posted a video of me getting data after a fresh wipe and install of L.
http://www.droid-life.com/2014/08/26/verizon-volte-hd-voice-launch/
I really need to remember to watch OP's video when I get home. This is very exciting. So to get data, you had to activate a Verizon device and swap SIMs, right? After that, the only thing not working is the CDMA voice? So in theory, if the above poser's link is correct (Verizon rolling out VoLTE soon) I could actually switch to them?
It's Verizon so I probably wouldn't do it permanently, but it would be cool to try for a month, if for nothing more than a proof of concept or neat trick. Hope Verizon does that soon.
This just won't work bro, not on CDMA.
I worked for Sprint and their system is the same.
The SIM card is strictly for LTE, everything else goes over the CDMA network, which requires server authentication.
Even when VoLTE will roll out, that authentication will remain in place.
People have got data in the past. Its voice that's the issue.

he can get voice & sms on it, though not via the sim card number;
I replied to the video with -
"..though it won't be your Verizon mobile number;
you could try using ring.to / grooveIP for voice / sms via the lte connection..
I use that as a back up number on sprint, mostly for lte , wifi , evdo routed calls,
even gsm / hspa+ & wifi when sim swapped out of the country on my nexus 5.
after editing the echo settings, it should work wonders thru that Verizon lte connection.."

just thought of something, real simple..
the cdma radio authentication is what's stopping the nexus 5 from being on Verizon,
but... **does the lte band need the same authentication**?
let's just say, on my nexus 5, with the new google voice hangouts / sprint number integration,
i go through the dialer into settings to toggle **lte only** which disables the cdma radio,
pop in a Verizon unlimited data sim, in an area with verizon's band 4..
over the top, voip service on lte..?

Caller ID and Spam Protection are greyed out on an unlocked phone.

I have an unlocked Note 8 bought from Amazon.co.uk and i am using it in Greece.
While my Galaxy S7 has the caller id option enabled on my Note 8 this option is greyed out.
Does anyone have any suggestions?

Unlocked using Verizon and it's enabled for me.
Probably there are a lot of people who do not have the same problem as i do. By just saying that you are ok you understand that you are giving me no help at all, right?
is that option only available on unlocked versions?
I think xbmoyx comment is certainly helpful as it indicates that unlocked Note 8 does support the feature.
My unlocked Note also supports it, using TMO as provider in the US.
I think there is no spam phone register in Europe/Greece yet, so the service is not being provided to you and that is the reason why it is greyed out.
Mine is grayed out but it is on. I am with t mobile.
It works on my unlocked phone here in the UK. I think the option is region specific.
--
Definitely sounds region-specific...like my old Galaxy S7 from Sprint that hid/restricted access to the APN settings menu. My S7 was sim-unlocked and I wasn't on Sprint anyways, so I was able to flash an unbranded version of their firmware which lifted those restrictions and provided normal access again to those features. Sounds similar to your case OP.
My phone had that working with hydra rom, when I installed 8 ported rom it no longer works, it also is greyed out in off position
got my unbranded/unlocked on amazon uk as well and it is also greyed out, I've no sim card in it at the moment though, maybe it depends if the actual service is available from your provider
You first have to go to advanced features, enable it there
You can also try downloading the latest software for the carrier you are using it on (from Sammobile or wherever), and then flash the Home_CSC file only.
That's how i got all my carrier features (and caller ID/Spam Protection) back.

If your phone was purchased through Verizon it's the 950U and the feature is disabled because they want you to use their pre installed caller id app instead. You will need to flash the latest 950U1 firmware for the feature everyone is talking about. Keep in mind if you flash this you will loose all the Verizon bloatware such as VVM and what not and your phone will be reset. Also the link I provided is the latest firmware as of today but I think another update is coming soon.

No problem, you can always flash back to the Verizon firmware if you don't like the 950U1. I did the same to my wife's S8+.

Will you be more specific? Where in advanced feathers should I change something and what exactly?
I mean I use S9 with U1 firmware, but still this Caller ID and spam protection feature is greyed out. I had it also in my unlocked S7 before with different operators I had been with. Also, I am sure it's not a matter of operator since my friend used the same phone with same operator, but had this not greyed out.
Guys, this issue will be Service provider related. I have two S10, same Model Number (SM-G973F/DS), same Software latest version (G973FXXUFHVE1), working on same network (Vodafone, Spain) so unlocked. One has Caller ID and spam protection ON but you cannot turn off, other is the opposite. Switched OFF and you cannot turn off.
But the Service provider software versions are different (CSC code):
Protectoin ON: .....AMO/AMO,AMO/AMO (Spain)
Protection OFF: .....BTU/BTU,BTU/BTU (Great Britain)
Maybe that's the key... i'm going to try to change BTU version to AMO on my second phone and keep you updated.

Have you been able to add new apn yet? I am having the same issue on my lg v40. I bought it from ebay and using abroad like you. Its sprint unlocked. I can call and send text but I can't use the mobile data. If you have fixed the problem already please let me know. It will be greatly appreciated.
Pretty sure this is a long-time known issue with Sprint devices. That function is disabled.
+1 to what grabber said. Sprint is a scumbag company, and even though they let you unlock the phone, they disable the APN settings in the firmware so you can't actually use data on other networks. I had the same problem a long time ago with an unlocked G5. Previous firmwares allowed it (I've heard), but by the time I tried, they started the disabled APN settings shenanigans.

I have been able to find a work around for my sprint lg v40. In my case if I turn on mobile data, it will be turned on. But I can't browse any site. I noticed one thing though I can use messenger and whatsapp for text chat only. Then I figured out its a problem with DNS in APN settings. As the APN settings is disabled I installed an app from store to change the DNS. This app will create a VPN profile for you just to change DNS. Now its working fine. Though I have to keep using the DNS changer all time. App I am using to change DNS is 1.1.1.1 .
I have had my lesson with Sprint. If I ever have to pick between Sprint and other carriers, I will stay 100 miles away from this scumbag.
If you update to US Unlocked Pie then you can edit your APN settings....i just don't know if it will remain Carrier Unlocked....

Cricket Wireless. You have to buy your phones on full but so much more freedom. You'll be on ATT network without paying the full price. I've been using them now for about 4 years having Sprint for around 7.

Page Plus uses Verizon Towers but you would need either a Verizon Branded phone or a Page plus branded phone and just like with any other prepaid carrier (including Cricket) you would have to buy full price...

The "guide" you talk about is the one that says to pay for the service?

Yes you pay for the bootlaoder unlock but the rest of the process to get to Pie is free

Question S21 Ultra locked? Unlocked? I'm not too sure! Help please.

Hey guys, first of, I want to thank you for reading the post.
So I've recently bought a new S21 Ultra from Korea, on the seller's page it was stated that it's unlocked. The issue I had when I received the phone is that it starts up with the carriers (SKT(Korea Telecomm)) splash screen, and what this means is that when I entered in. I was forced to install all of SKT apps. And I can't disable them or anything. And when I put in my local sim card to test it, I could call people and it was technically working fine. But when I was using mobile data. It only activates 3G/LTE, although my sim is 4G+ and I've been using it with my all phone all the time. I've also come to noticed that there is a SKT connection thing in my setting, and I noticed that my local sim card is actually classified as a overseas sim card. So it's as if the phone is thinking I'm mobile data roaming all the time. I need help with this, is there anyway to get rid of it? I've got a screen shot to explain what's happening.

I think so as well. Man....
No.. what are you talking bout? You didn’t buy it from Samsung? you’re phone is unlocked! How else are you able to make calls?? You would have no service and your phone would give a SIM card error if it was locked. You need to change your APN settings according to your carriers. Thats it you’ll have full speed internet after you change your APN settings, to your US carriers APN, it’s currently on the Korean carriers that’s why it’s showing as overseas. Google APN settings for your carrier.
Your splash screen will always show the Korean carrier cuz it’s their device originally, if you want to change it you have to root it first. Dudes splash says Samsung cuz his is factory unlocked, it never was locked to any carrier. He bought it from Samsung directly which is why there’s no carrier stuff anywhere.
Yo OP if someone says something weird you don’t have to agree with them, you should ask them to clarify instead, that way you can correct them if they’re wrong which in this case you missed, they pointed you in the wrong direction, which certainly didn’t help you. To an outsider like myself you both seem crazy, obviously y’all have no idea what y’all talkin bout and I know it didn’t get resolved cuz the only way is my solution.
Do you reside in Korea, if not why aquire the Korean variant? If you add up all the different S21 Models then factor in all the different Service Provider's it's over one-hundred different variants. That's pretty much on Samsung, no other device manufacturer has anywhere near this many variants, it's absolutely absurd! Anytime you install firmware that doesn't match your device’s Primary CSC you should expect conflicts. If there's any comfort in the fact that thousands if not millions of users are in the same boat as you. If you need full Call Feature Compatibility it's always best to aquire your Service Provider's device. A bit of research goes a long ways when it comes to Samsung's numerous offerings.
You have to change the APN to which ever carriers APN you are using... that simple.
If you don't know how to do so. Let me know
