Patent ID: 8463265

Claim:
A mobile communication terminal comprising a first identity module; a second identity module; a detector configured to detect whether the mobile communication terminal is in a coverage area of a reference mobile communication network of the first identity module; a controller, configured to, if it has been detected that the mobile communication terminal is not within the coverage area of the reference mobile communication network of the first identity module, determine a reference mobile communication network of the second identity module, and to start a registering process for registering the first identity module with the reference mobile communication network of the second identity module, wherein starting the registering process comprises determining whether the first identity module is allowed to be registered with the reference mobile communication network of the second identity module, wherein determining whether the first identity module is allowed to be registered with the reference mobile communication network of the second identity module comprises determining at least one of whether an operator of the reference mobile communication network of the second identity module agrees to the first identity module being registered with the reference mobile communication network of the second identity module, whether an operator of the reference mobile communication network of the first identity module agrees to the first identity module being registered with the reference mobile communication network of the second identity module, and whether a user of the mobile communication terminal agrees to the first identity module being registered with the reference mobile communication network of the second identity module.
