Does UT Nexus 5 work on AT&T? Are my APN settings the problem?

[Nigel-tufnel]

Just wondering if anyone has successfully got the Nexus 5 working on AT&T? My UT Nexus 5 doesn't register an AT&T sim card but sees a T-mobile sim. I'm not sure if this is due to missing APN settings or if AT&T and the Nexus 5 don't play nice. Phone is supposed to be an unlocked GSM phone.

Any feedback appreciated. Thanks

@nigel-tufnel APN settings will only matter for mobile data and MMS. If the phone does not register at all, thats a different issue then. I am afraid you need to find an American user for confirming that, however.

@Nigel-tufnel I'm on the same hardware and indirectly using AT&T (an mvno derivative). For the most part, things have been working well for me...data, text, and calls.

Not the expert here, but have you confirmed it's actually unlocked? ie: get it to the bootloader and run fastboot oem unlock from your machine?

I'm on OTA-16 here and it worked on the build version (from Nov/Dec '20??) before as well.
