Max Transit Duo currently with Verizon on channel 1 slot A and AT&T on channel 2 slot A. Want to add T-Mobil to channel 1 slot B. Is this possible? How do you set up the second slot as a different carrier?
You set network mode to “auto”, and the modem will work with whichever SIM card/carrier is the current connection.
You then proceed to configuring how the modem decides which SIM card to use at any given point in time.
cheers.
