A machine-to-machine device is configured to execute an application (providing meter readings, for example) and comprises a cellular network interface for wireless communication of data with a cellular network. It has subscription information allowing it to register with more than one cellular network. The device may be registered with one cellular network, selected as having a received signal quality (e.g. RSSI) measurement of at least a predetermined level that is based upon a quality of service level defined by the application. It is also provided that the device may identify that a quality measurement for a packet-switched communication link fails to meet a predetermined level. In response, the machine-toÂ-machine device may be deregistered from one cellular network and registered with another cellular network. This allows the M2M device to only register with a network that is able to provide at least the minimum service level to enable required data transmission.
