I just got rid of my AT&T edge and got a tmobile one, I wasnt about to go to best buy and get updates all the time like I was told by samsung
You need an AT&T sim it doesn't have to be activated. Im using mine on cricket and got my latest OTA by putting my deactivated AT&T sim and using my wifi to download. I did have to check twice and reboot once to trigger the update. If you change the time in settings up a day you don't have to wait 24hrs to recheck for update.

I have an unlocked AT&T S7 Edge and use it both on Rogers and AT&T, I simply change the SIM depending on where I am. The updates still come from AT&T regardless of where I check for them.

Fair enough.
You still get your updates when you have the AT&T sim in the phone.
I do not have AT&T service at all and am totally unable to get any updates.

I am in Canada with my Rogers sim installed and received the latest update from AT&T on Friday last week. I have received multiple updates from AT&T when in Canada with my Rogers sim installed since getting this phone.

I have been unable to get even one update on 4 phones with a Cricket Wireless SIM in.
I dont understand it, AT&T Owns Cricket, you would think it should work without any issues.
I have a very interesting question regarding on using tee AT&T variant of this phone on the T-Mobile network. As you may have noticed, AT&T is finally offering Wi-Fi Calling on their network, and this phone is compatible. My question is:
Does the T-Mobile Wi-Fi calling work on the AT&T variant of this phone?
Does the AT&T Wi-Fi calling work on the T-Mobile variant of this phone?
If you flash the U firmware, you'll get wifi calling, VoLTE, and OTA updates. There is a thread in one of the other AT&T forums that has instructions.

You could also go another route and flash the t-mobile firmware on the at&t variant, it works quite well and is the equivalent of the U firmware with t-mobile account management, voice mail, and features.
I have s7edge at&t ..it don't have any volte option
I want to enable volte option. On my mobile
If i flash sm-935U on my at&t will it activate VOLTE OPTION
If you switched to TMobile just ODIN the Tmobile Firmware and you will get the updates OTA.

Yeah you do, its under Connections/Mobile Networks/Mobile Data its called Enhanced LTE services....I actually shut mine off and its saving quite a bit of battery it seems and I havent even noticed a difference in phone call quality, seems kind of useless
you need to get or buy a Gophone simcard or buy a gophone (comes with Gophone simcard), just activate the gophone simcard, you dont need to pay money on it. i never able to get att software update using Cricket simcard but when i put a activated gophone simcard (no need to pay money on it), it lets me update to the latest att firmware ! funny, how gophone and cricket are owned by parent company att but gophone lets me update and cricket can NOT.
I've searched and cant find anything but the bands for either service. Which they use a lot of the same. Is a T-Mobile branded S8 usable on Verizon? Full 4G or not? Thanks!
its a gsm device. i believe the internet data part will work but not phone calls

Darn. I was hoping since they all have the same model number that it would be possible.

Call Verizon with your IMEI # and they can check if it's compatible with their network.

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

Don't know about Digits because I don't use it, but Wi-Fi calling does work. I get the T-Mobile boot logo too.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel
@T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.
This has been discussed before but I'm still not 100% clear.
Can I buy an unlocked Galaxy s8 plus that comes from a different carrier (say Sprint) and flash the AT&T firmware to it, changing the carrier identity so that you get features like wifi calling and VoLTE?
Thanks!

Yes you could get it working with wifi calling and voice over LTE no problem but you got to make sure that if you get a phone like from Sprint/Verizon / T-Mobile unlocked before trying to carrier switching

Thanks for replying. So make sure I have this right.
If I purchase a Verizon/Tmo/sprint Galaxy s8 plus and put my AT&T sim in it and it activates on the network and allows me to make/take phone calls then I can assume that the device is unlocked. If it's carrier locked that should not work.
Yes that is correct but if you want to have all the AT&T features you must carrier switch following instructions here on XDA which will convert your Verizon/ Sprint S8 phone and to a completely AT&T phone

Riddle me this. I have a guy trying to trade me an S8+ att version for my OP5. He says it is unlocked. Can I flash unlocked firmware on it to get rid of any bloat and all the att stuff in the background that will be taking my data?
Anyone know how to get VoLTE to work on cricket, with a non-branded cricket phone? Cricket is telling me it has to be a Cricket-branded phone. Does that mean specific IMEIs or could I just install Cricket S8 software?
Also, does anyone know if VoLTE will work on Straight Talk using Verizon's network? Thanks for any help.

I would think flashing the cricket firmware and csc would be enough as they are not lying the prscess to convert a non cricket BYOD is rough I Tried on a verizon LG G5 And still never got it working properly

I will try this. Do you happen to know if Cricket is 950u or 950u1? I can only find AIO (cricket, i believe) for 950u1. Would I need to change the CSC if I use official cricket firmware?

I believe so on the csc but there is 950u1 and u2 you have to look in your settings to see which you are on the u1 or 2 is the bootloader version f it is u2 U cannot flash any U1 firmware
Verizon prepaid was great with VoLTE BYOD. All 3 of my family's phones worked (HTC U11 unlocked, iPhone 6, Samsung J7 Verizon). It was beautiful sound quality. I had to ditch Verizon, because, despite having a strong signal, 4G LTE data performance was very unpredictable. Sometimes my download speed was essentially zero at my home, even though I had 5 bars. One morning during a power outage, I had a good strong signal, but I couldn't bring up a single website using the HTC U11. The Verizon branded Samsung J7 wasn't much better. I called Verizon prepaid support a couple days later, and they had me do the usual ridiculous insulting troubleshooting where they try to blame the user/device. Also, I did hate that there was no visual voicemail app for Verizon on prepaid plans (makes no sense). That being said, I went back to Cricket in order to get normal LTE data performance, even though I get one bar of signal at my home. Now, back on Cricket, the sound quality has returned back to horrible when I call home from work, but data is pretty good. Also, I cannot stand that my unlocked HTC U11 cannot use the hotspot functionality on Cricket without my paying extra. The HTC One A9 my family member uses can serve a hotspot, probably because it's S-OFF and rooted. Verizon prepaid allowed anybody to serve out a hotspot for free. Today I tried an experiment. I called home using Google Duo. My phone and my family member's phone have Duo installed. The sound quality was incredible and sounded just like HD Voice. Essentially, it was a workaround to get VoLTE. The phone at home was on WiFi, and I was using 4G LTE. So, my poor-man's HD Voice will end up carving out bytes from my data allowance. I don't know when and if Cricket will open up all VoLTE capable phones like Verizon did. It bugs me that Verizon had this weird data issue, because Cricket seems to be game playing even more than T-Mobile and Verizon do. I was tempted to try T-MOB again, but they have this ridiculous policy with their prepaid family plan where you have to make a deposit that they keep for a year. Who does that?
If I buy used T-Mobile can I Flash AT&T firmware on it so I will have AT&T Enhanced Messaging and Wifi Calling Just as if it was an ATT phone????? Thanks
If the phone is network unlocked in theory the sim it sees when you first boot from setup it should then download all the carrier software and features. There is only one carrier U firmware so there isn't specific AT&T, T-Mobile. Now if AT&T tracks their IMEI's that were meant to be on their network then that may be where this all falls apart and some features may not come over then.
At least that is how it has worked in the past. Someone else feel free to correct me if I am wrong.

I saw a report on the forums here where someone flashed the att userdata and wiped and all of the carrier features worked.
I know on the 9/9+, even with the BOYD firmware, or flashing att bloat would not make a NON-ATT purchased device have advanced messaging /wifi calling / VoLTE. The trick was to activate that stuff on an att branded phone and then swap the sim.
It was very much a YMMV.
Similar issue here. My problem is i bought a s10 plus AT&T and it was supposed to be unlocked, however it wasn't the case. Mine is still AT&T locked and when i called them about my issue they said i would have to get service with them for a few months then i could end the service by paying the cancellation fee. I could then unlock the device. They also told me that my phone has an unpaid balance that would have to be paid prior to starting service. I have tried to contact the seller but to no avail. Anyways, my question is can I flash T-Mobile stock firmware to this phone and use it on T-Mobile?
