Method/device several telecommunication networks terminal connecting having subscriber identity module and steps searching terminal radio coverage for module/base network attaching/reinitialising/connecting where network different.

摘要

The connection method to a second network has a radiocommunications terminal having a subscriber identity module with an integrated circuit, communicating with a second network using data sets. The required radio terminal covering the area is searched (60) for network on the subscriber identity module, the terminal being attached to a base network, and reinitialisation (110) and attachment (120) of the terminal to the reference network if this is different to the base network.
