Thanks for the APN advice. I’m good there.
Also done everything but a hard reset and reflash. I don’t think it’s an issue with just our phones. I talked to some Cricket people who were aware of the problem, and told me it wasn’t affecting new activations, just old customers, and they’d heard from other Cricket people that Cricket (ATT) was actually deliberately disabling LTE voice to shed load during the transition, and they were only doing it to old, long-term accounts, presumably the most likely to put up with it, or something.
ATT is essentially a telecoms branch of the NSA, and the most evil of the carriers, so this wouldn’t be surprising. But the Cricket girls thought the transition would be done by end of March, so go figure.
The only reason I am with Cricket/ATT is coverage. If TMo was where I needed them, I’d never have left.
Thanks for bringing the ‘known issue’ post to my attention: at least I now know for sure it’s not my phone, it’s ATT.
I tried again to call Cricket techs, but 13 minute hold time listening to their stupid music and advertising? No. I wish I could dump them: they’re just that bad.
