Can't connect to cellular network - phytocube - 06-18-2022

I have an Airvoice SIM card* I've been trying to get to connect, but it's not working. NetworkManager seems to detect it properly and lists the correct SIM ID and even reports that the carrier is AT&T. I've tried using both "reseller" (no quotes) and "NXTGENPHONE" (no quotes) as the APN, but it never successfully connects. Here is some of my journalctl output matching /modem/i:

  1. Do I need to issue modem commands manually to troubleshoot/fix this? I don't know how to do this, having relied on NM/MM so far; if it is, what's the best way to do this?
  2. Am I just not in the service area? I somewhat doubt this because I'm in a relatively densely populated area, but what I can understand from searching the reject causes suggests this might be the case. (I'm reluctant to switch to other providers mostly because I haven't found any prepaid plans less than 3x as expensive, but if it can't be avoided...)
* Compatibility unknown per the wiki

ADDENDUM:
Per this thread, it appears AT&T is no longer a viable carrier for PinePhones: https://forum.pine64.org/showthread.php?tid=15988
