Hello everyone. I'm experiencing a very mysterious problem with my SIM800L module. Yesterday it would connect perfectly to the network and I could send SMS and stuff. However, today, it detects the SIM card, accepts the PIN but returns 0, 2 on AT+CREG, because it doesn't connect to an operator. Running AT+COPS=? returns nothing. Please help me.
did you change anything?
Power supply good and dedicated to the module?
No short circuit happened by mistake?
