Abstract

Cellular telephone handsets often include electronic or software coding that “locks” them to a specific wireless network. Provided herein, is a method for provisioning locked handsets by unlocking them from their established network and relocking them on a new cellular network. The handset is connected in communication with the control process, identified, and provisioned. The method allows for provisioning of multiple models and brands to be provisioned from different carriers and to different carriers. It further allows multiple handsets to be provisioned simultaneously. During the process, the handset may be sensitivity tested. Further, the identification portion of the method can be used in conjunction with phone support tools beyond the provisioning process.
