I can’t seem to make a phone call or send an SMS using my AT&T micro sim card. The card inserts ok and the screen does NOT say “No Sim” so it seems to detect it but when I try to make a call it stops after awhile and an SMS says “failed”.

Could this be because AT&T is phasing out 2G phones? Is that was the RePhone Create kit comes with?

Any other thoughts?


Answered my own question. I forgot I was using a different GSM module where I hadn’t attached the antenna!! Once I attached it was all good. (of course) :slight_smile:
