Computer-implemented techniques involve detecting, by a server having one or more processors, a first cellular connection between a computing device and a first cellular network of a first cellular carrier associated with a mobile virtual network operator (MVNO), detecting, by the server, an outage of at least the first cellular network of the first cellular carrier, in response to detecting the outage of the first cellular network, determining, by the server, an alternate communication channel by which to communicate with the computing device, and transmitting, by the server, a carrier switch instruction to the computing device via the alternate communication channel, wherein receipt of the carrier switch instruction causes the computing device to: (i) terminate the first cellular connection and (ii) initiate a second cellular connection with another cellular network of different second cellular carrier associated with the MVNO.
