I'm using a SIM800L module, and I am checking the status of my network with the AT+CREG? command.

However, it always returns the same 0,2:

0 -> disable network registration unsolicited result code

2 -> not registered, but ME is currently searching a new operator to register to

How do I activate 2G or 3G network?

  • It can take a while to register - sometimes several minutes. Have you left it after power-up for enough time?

  • If your operator has no signal in your area it will never register. National roaming is normally disabled. If you have national roaming available you will have to manually connect to another operator.

  • Check that your modem can see your operator with AT+COPS=?

  • I can see the operators list with command AT+COPS=?. But I can't register on them! Nov 25, 2016 at 14:54
  • Do you need a pin for the simcard?
