You could try get att to provision your phone and sim card but have to stop at store for that , but I'm afraid you'll end up doing factory reset in the end .

I want to try to reflash my Note to ATT so I can use WIFI calling...can I step by step instructions (instructions that were verified to work) with the exact files I need from someone?? I have to get this working or I have to buy another phone. Thank you for your help so far.

Feb.….Ok...good news. I called ATT and told them to put an old iPhone on my account (IMEI)…..didnt tell them what I was doing. Restarted my Note and all is working.....is this a permanent fix?

I have note 10 plus from tmobile and flashed unlocked firmware and was using on AT&T without volte and wifi calling. Then I decided to try and flash AT&T firmware and now I have wifi calling and volte.

 

[Matthew Stegman]

first I have read and read and read.....and I still am unsure if flashing to a carrier firmware (ATT) on my unlocked Note 10+ gives me WIFI calling.....yes or no?? I flashed to ATT firmware and the icon is there, but i keep getting the "OOOPS" message, saying that it cant be activated. I called ATT and was told even though I have ATT firmware, they still cant get WIFI calling to work..

any ideas? what is the latest...is it possible to get WIFI calling on a flashed unlocked Note 10+?

thanks

I flashed this firmware and I have all AT&T apps and all advanced features including volte and wifi calling!
