Various arrangements for permitting a wireless device occasional access to a wireless network are described. Some arrangements for assigning a single MSISDN to multiple wireless devices are described. In such arrangements, the wireless devices may be associated with different visitor location registers. In some arrangements, a wireless device-initiated bearer service is initiated based on input from a remote system. In some arrangements, a wireless device is authenticated based on whether data needs to be sent to and/or received from the wireless device.
