I saw this linked from MacRumors during the AT&T iPhone 18 Pro Max lockup news discussions. It was interesting to see what AT&T/Apple did to try to get ahead of the issue. So far it looks like they disabled 5G Standalone mode, possibly just to prevent a bug from literally destroying the hardware (possibly only on one batch of phones).
Apple/AT&T still haven't released any kind of statement addressing the issue other than to replace affected hardware.

This is super cool. Particularly for the fact that it just showed my country's operators rather than the usual America First.

A while ago I built a decoder for that (Qualcomm only!), it was fun and helped me improve the support of my device for my carrier.
