What is the best way to determine carrier?

My company is planning on using the MC7354 with two different carrier configurations. What would be the best way to detect which carrier the modem is configured for, so I know which apn, etc. to use? I am using the modems on armv7 linux hosts with the libqmi driver and freedesktop.org’s modemmanager.

I hope the AT commands AT!PRIID and AT!PACKAGE will help you…

You can refer the AT command guide:


How can you determine the carrier of a device by model number? For example it looks as though a given model can run on AT&T or Verizon simply by changing firmware. What about Sprint? Is it different hardware?
