Has anyone had any luck getting the RM530N-GL to work on AT&T? I was told by the seller it’s compatible before I bought it, but that does not seem to be the case. I have an active 5G AT&T SIM and an active 4G SIM. Both give me the “NETWORK ERROR” message in the RM530N-GL, and AT&T Customer Service tells me the IMEI is invalid on their system.
Dear @Lormar
AT&T has strict IMEI whitelisting policies for cellular IoT devices. Devices must complete IMEI registration to function normally on AT&T’s network.
