• sending a first attach request as part of a first attach procedure to the cellular network using the first mobile equipment via a first base station to establish a first communication channel to the cellular network;
• and
• sending a second attach request as part of a second attach procedure to the cellular network using the second mobile equipment via a second base station to establish a second communication channel to the cellular network,
• wherein the first attach procedure and the second attach procedure are performed using a same subscriber identity provided by the single subscriber identity module and wherein, upon completion of the first attach procedure and the second attach procedure, data communicated between the wireless device and the cellular network is transferred redundantly over the first communication channel and the second communication channel.
