I ordered an upgrade board to swap into a UBPorts edition I have. Swap was successful and the phone could detect all hardware when using factory test but I experienced odd behavior when I put a SIM in it.
The phone would detect the SIM was inserted and even show signal strength and type ("bar meter" and 2G/3G/4G notifications in top left of phosh) but the modem would never register with the network. Specifically the modem details would show signal type as "lte" and provide a signal strength metric but the network status would be "unregistered."
I swapped the 2GB ram board back in and the phone works now...
Really at a loss here, has anyone ever seen this behavior? Was I supposed to do something with the modem after swapping the board in? I was so close to USB-C!!!

Some things:
- No, the SIM doesn't have a pin
- Yes, the SIM is activated
- SIM is an AT&T BYOD straight talk
