Alright, I'll go to a T-Mobile shop (or reseller) in the next few days to get a test SIM.
In the meantime, I tried running the AT commands with socat, but didn't get very far. Maybe I'm using socat incorrectly - I haven't done it before, so forgive my ignorance. Following is the transcript from my console session (done over ssh from my laptop): root@neo:~# socat - file:/dev/ttySAC0,crtscts,crnl ~ +CREG: 3 ~~ ERROR @~~ %CSQ: 18, 99, 2 ~~ +CIEV: 1, 3 ~AT+COPS=? ATE1 ~ %CSQ: 15, 99, 1 ~~ +CIEV: 1, 2 ~AT+CFUN=1 AT+CGMI The commands 'AT+COPS=?', 'ATE1', 'AT+CFUN=1', 'AT+CGMI' were entered by me. I'm guessing I should have seen at least a 'OK' or 'ERROR' message, so maybe I'm using socat incorrectly? I don't have a 3G USB modem, unfortunately. I'm pretty surprised that the carriers are decommissioning 2G in the USA. Crazy bastards. Thanks for your continued help.
