Configuration data 230 may be provided to a device 110 by a configuration server 120 that is configured to output configuration data for sending to the device 110, wherein the configuration data comprises preferred or barred communications bearer data indicating at least one preferred or barred communications bearer for a device communications interface. Preferred communications bearer data indicates a plurality of preferred communications bearers and can be ordered by degree of preference. Configuration data may further comprise a signal strength threshold for one or more of the preferred communications bearers. The device may be a machine-to-machine, M2M, device. The configuration server may be configured to output the configuration data using OMA lightweight machine-to-machine, LWM2M, protocol. Data can be provisioned to the device off-line during device manufacture, or the installation of a new SIM card. Preferred/barred bears can include 3GPP PS, 3GPP PS GSM GPRS; 3GPP PS UMTS; 3GPP PS LTE; 3GPP CS, 1xEV-DO; WLAN; Ethernet; DSL; Bluetooth; WIMAX. |
