What is the procedure to automatically detect the network operator ( AT&T, Verizon. T-Mobile, Vodaphone etc)?
Hi akn,
I think it is the same as Automatic detection of the APN for a particular carrier
- Configure empty APN: AT+CGDCONT=cid,“IPV4V6”,""
- Reboot device (if any), wait for device registers to network.
- If the registering is successful, check apn with AT+CGDCONT?
If it is not, please set particular apn for each operator (you set only 1 time if you don’t change the network’s SIM).
Note that: remember to set all supported bands for device.
Thanks,

Can I perform it without rebooting the ME?
Yes, if you don’t want to reboot device, you can detach and attach network again
- AT+CGATT=0
- AT+CGDCONT=…
- AT+CGATT=1
Thanks
