Saturday evening, OxygenOS 220.127.116.11 update came out. After that, no data/calling is available on my phone. I have a Oneplus 6T, and I've tried everything I could find on forums except for the total reset. When I restart my phone, it LOOKS like it has service but no data for a few seconds, then goes to no signal.
I sat online with a tier 2 support tech for hours troubleshooting yesterday and he couldn't figure it out. I hear about the APN settings not being correct, but I have no way to edit.
mobile data reset didn't work. sim swap didn't work. tried a handful of other reset/data clearing options with the tech support including resetting the line on the carrier side.
I am running two separate Verizon SIM cards linked to two separate accounts (work and personal) and they are both having identical issues.
