Abstract
A method for reactivating a telematics device configured to make a data call via a roaming partner of a service provider is disclosed. The service provider has an authentication bypass feature which uses an authentication bypass key common to the telematics device and the service provider to allow the telematics device to make a data call without authentication. The method comprises setting the authentication bypass key on a server of the service provider equal to a previous authentication bypass key, wherein the previous authentication bypass key was used by the authentication bypass feature prior to deactivation of the telematics device. The method includes setting the authentication bypass key on the telematics device equal to the previous authentication bypass key. The method further comprises commencing the data call through the roaming partner by sending the authentication bypass key to the service provider from the telematics device via the roaming partner.
