Roaming

Each module vendor has their own commands to enable roaming (it is not a standard AT command). Below we list the commands to enable roaming on a few modules types.

Quectel

To enable roaming on Quectel modules, we can use the following AT command:

AT+QCFG="roamservice",2

U-blox

To check the network registration status of the SIM, we can use the following AT command:

AT+UDCONF=20,1
