Hi everyone, I'm on an unlocked/rooted/xposed G928T on AT&T, and I'm wondering if it's possible to enable those features through my AT&T SIM. When I enable WiFi Calling in settings, it simply pops up an "invalid SIM" error as I'm not a T-Mobile customer.
Furthermore, even though I have the proper APN set up and AT&T has an iPhone 6+ IMEI in the system for my SIM (so VOLTE is set up on their end), I can't seem to get VOLTE to work either.
Any ideas? Perhaps I need a system dump of the AT&T version to piece it all together?
Thanks in advance!
