    • A technique for providing reliable wireless communication between a wireless device (702) and a cellular network (704) is disclosed. The wireless device (702) comprises a first mobile equipment (710) and a second mobile equipment (712) sharing a single subscriber identity module (713). A method implementation of the technique is performed by the wireless device (702) and comprises sending a first attach request as part of a first attach procedure to the cellular network (704) using the first mobile equipment (710) via a first base station (718) to establish a first communication channel to the cellular network (704), sending a second attach request as part of a second attach procedure to the cellular network (704) using the second mobile equipment (712) via a second base station (722) to establish a second communication channel to the cellular network (704), wherein the first attach procedure and the second attach procedure are performed using a same subscriber identity provided by the single subscriber identity module (713) and wherein, upon completion of the first attach procedure and the second attach procedure, data communicated between the wireless device (702) and the cellular network (704) is transferred redundantly over the first communication channel and the second communication channel.
