Abstract
A method of responding to a network connection failure in a mobile communication device. The method comprises receiving an error message indicating a data connection failure, activating an application configured to attempt to access the network using a first identifier on the mobile communication device in response to receiving the error message, sending an SMS message from the mobile communication device over an SMS control channel in an attempt to access the network, receiving information indicating a failure to access the network through the SMS control channel, determining that the failure to access the network is based on the first identifier, performing a limited reset of the mobile communication device to replace the first identifier with a factory default identifier, confirming through use of the factory default identifier that the first identifier is inactive, and establishing the factory default identifier such that the mobile communication device is configured for activation.
