I have a Max BRI MK2 with a verizon and an ATT SIM cards. Verizon’s signal tends to be stronger so the device defaults to the Verizon card and uses all my allotted data. The ATT card is rarely utilized. Once I have reached capacity I would like to force the device to use Att. Is this possible to do remotely as I am unable to access the router. It is located in a dome on the roof of a boat.
