Why does my original iPhone SE not support VoLTE?
Supposedly all iPhones starting with the 6 support VoLTE. The SE came out after the 6 and so should support VoLTE.
When AT&T announced a couple of years ago that it would be requiring VoLTE for voice, I thought I'd be ok. But since AT&T implemented a requirement of VoLTE for cellular in my area, I cannot use my SE. (I tried reinitializing network settings but that made no difference.) In network data settings, there are options to choose 4g, 3g, and 2g, but no LTE or VoLTE options. At the top of my screen, it says I have a 4g connection.
My iPhone 12 Mini gives me 5g and LTE options, and also a VoLTE option. When connected to AT&T, at the top of my screen it says "LTE" and I can make voice calls over AT&T.
So, should my SE be working with VoLTE or was the "6 or later" info incorrect?
iPhone SE, iOS 15
