My phone is an unlocked AT&T phone. It has AT&T bloatware. The serial number indicates it is an AT&T phone. The service provider software version is ATT. I bought the phone so I could use the wi-fi calling feature which is nowhere to be found. Put the AT&T SIM in my son's phone and he has wi-fi calling. AT&T's website gives the latest firmware as G970USQS5GUF1. My phone was just updated OTA to G970USQS6GUI1 which happens to be the T-mobile firmware. I put a T-mobile SIM card in the phone and I now have wi-fi calling. T-Mobile coverage is basically non-existent in rural Appalachia so I don't want to switch carriers. I have read numerous posts that say the basic firmware is the same for all carriers. So, my question is which files do I need to flash to get wi-fi calling working on my phone? Also, I can't really go back to BL 5 can I? I am totally new to this although I have flashed a Moto before.

So,
I have an ATT FUZE phone and service right now and it is SIM Unlocked.
I can also install any ROM (SuperCID?) and I just flashed the rom to ATT's latest Radio/WM6.1 last week.
I'm considering switching to Verizon using the same phone because ATT reception is crap
I'm assuming I can still use the latest ATT Radio (they're all GSM right?) and won't have to reflash the radio to Verizon specific? I should just be able to get a Verizon SIM card and everything else should work straight off the bat no? I know the phone will work with the Verizon Sim.
My concerns are the data -radio wise and speed and reliability with the ATT (specific?) radio.
Thoughts?
Sprint and Verizon are both CDMA.

Well the problem is that AT&T is GSM Verizon is CDMA the phone will NOT work on the Verizon network. The only SIM cards for Verizon is for international calling not domestic and will not work in the states. Sounds like a great plan but it will NOT work. Sorry for the bad news.....
the Fuze is a GSM phone, thus it will not work on Sprint or Verizon. The CDMA version of the phone is the Sprint Touch Pro (will work on Verizon or Sprint). I would see your Fuze on ebay, and us the money to buy the Sprint Touch Pro then switch to Verizon.
DO NO BUY THE VERIZON TOUCH PRO. IT HAS LESS RAM (192mb vs Sprint's 288mb). The Verizon version of the Touch Pro is a waste of money, so make sure to get the Sprint version - you can use it on either network.
Hi,
Recently got a Koodo GTi9020A and have tried to use it in the UK with a 3 Sim.
The phone gets a full 3G signal, data and internet work, however there is a problem with making calls when using the 3G signal.
When the phone is turned on I can make one call to a landline, however if I hang up and dial again there is silence. Calls to other mobiles are scrambled.
I have spoken to Google and have been told that the Canadian software will not work with a UK Sim and the phone will need flashed with UK software.
The phone is therefore 'locked' to the Canadian networks. The lady from Google mentioned that a fully unlocked phone would be more expensive!
Any advice appreciated.
Thanks.
I just got a Sprint phone and I am in the process of unlocking it. Once I unlock it, should I flash the Sprint S7 with the T-mobile S7 firmware since T-mobile is my provider? I know I won't get wifi calling and VOLTE, but I figured the preconfigured settings on T-mobile APN etc will make it easier for me to use the Sprint phone with less issues? The other option was flashing the International unlocked firmware.
What are your guys' thoughts?
Hello everyone,
I bought a samsung s10e that I suspect is the AT&T version G970UZKAATT. This phone is supposed to come sim unlocked.
- Does that mean that when I insert a TMob sim card, will it reboot like the S9 and the TMobile logo will show up, then
the phone will work just like a regular TMob version G970UZKATMB?
- Will it have wifi-calling for TMob?
- Will it support all TMob LTE and HSPA frequencies e.g. band 71?
- Do all versions of the G970U support the same frequencies once unlocked just as these websites suggest?

Hardwares all the same. No, it wont boot with a Tmob logo. If you want it to act like a Tmob G970 flash the Tmob firmware.
I was just testing a S10e that has G970U1 as model (probably flashed) on the back says G970U.... I inserted an Ultra Mobile SIM card (TMob mvno) and it seems that the wifi calling works on the unlocked ROM .... So no need to flash TMob version, I believe.
Can anyone confirm wifi calling works on the factory unlocked version?
I have the g970u1 factory unlocked with u1 firmware. It has tmobile wifi calling. The only things missing are tmobile video calling and that rcs messaging I think. But, I flashed the tmobile u firmware a couple months back and the phone booted up like a tmobile branded one with the jingle and stuff. I didn't need those so I reflashed the u1

Thank you so much for confirming. I've just got my g970u1 factory unlocked and wifi calling with Ultra (TMob mvno) seems to work too. I tested using airplane mode enabling just wifi and I can still make calls
No wifi calling option on S10E (SM-G970U1)
Model: SM-G970U1
Andriod 10: one UI: 2.1
G970U1UEU4DTF3
Using MVNO ATT SIM.
No wifi calling option to turn off/on in the dialer app, no VoLTE. MVNO said I am confirmed to enable both options though.
Is this an ATT sim restriction for unlocked/non ATT devices? I did plug in my wife's att sim card and was able to get LTE+ but no wifi-calling. This isn't a branded ATT S10E.

I have an Unlocked S10e (U1) and the only way that I could get those AT&T features was to flash the "U" firmware AND the AT&T User Data file that has all of that crappy bloatware. I also used my old AT&T SIM card that had been in AT&T's system for years on previous phones. I had to do the same thing with my Note10+ too.
Another S10e that I have is still on U1 firmware & I just popped in a T-Mo SIM with no problems. Wifi calling etc. Work except I needed to download a visual voicemail app. Otherwise working great.
AT&T makes it so difficult!
It was a must for me because I have poor AT&T service where I live & need wifi calling.

Thank you, that is what I expected from ATT. I will switch to verizon MVNO. I don't want to have an unlocked phone, only to be forced to install carrier bloat.
