VoLTE is broken for some carriers, try to disable itI found extremely bizarre problem with this ROM. It just won't dial with my AT&T SIM. Seems to be working fine with other carrier(s) just not AT&T - I don't get a dial tone. Data is working fine. SIM is also working fine in my other phones, or with stock ROMs (for as long as I care to keep them).
Could it be VoLTE thing? Is VoLTE supported in this ROM?
