I am looking for a modem where I can use AT commands to set the EARFCN (channel number) for LTE or 3G networks. I saw some documentation of AT commands for some Quectel modems that may support it but I want to confirm: is there a Quectel modem that supports setting EARFCN using AT commands?
Do you need a module that supports 3G and LTE?
Yes, and even 5g if possible
Do you know any models that support it?
you can use RM520N-GL、RG520N-EU、RM551E-GL
