How is LTE carrier switching performed on the MX67C integrated LTE modem? I have two SIM cards, one AT&T and one Verizon. Both have been activated with the IMEI address of the MX67C's integrated LTE modem. the modem will only come up and connect on Verizon. When the AT&T SIM card is installed modem status simply says "Enabled" and shows no LTE connection.
Does the MX67C automatically switch LTE carriers based on inserted SIM card, or do I have to manually do some process when moving from AT&T to Verizon?
I have a question concerning the cell plans around the LTE modem since it seems like you have already been through that process. And I am assuming you need to purchase a monthly data plan for the MX67C? What are the options? cost?
I was able to get it to work on FirstNet (with black sim) with an apn of firstnet-broadband. Our rep advised not to use FirstNet cause it's not FirstNet-capable - but it did work, even if no band 14. AT&T sim did not work. Going to activate a Verizon card to see if it works. Probably just have to light up sim, power down MX, replace sim & power back up.
