EM7455/EM7430 Find Data Usage of SIM inserted in the Modem

IoT Modules
1

Hello ALL,

I use SIM cards from ATT, Sprint etc in EM7455 Modem and sometimes they reach High CAP limit set by
Carrier and stop working. I am wondering is there any mmcli or AT commands to check where they are
blocked by carrier. I am using Linux .

Thanks

@prap4network,

Unfortunately there is no data counter on the unit that you can access through AT commands, there are some options in the QMI SDK.

@prap4network,

You meanif it has attached, yes, there are AT commands and QMI API’s.

at+creg?
at+cgreg?
at+cereg?

Suggest you look in the command manual to see what they mean.
