Method for switching from a first to a second mobile network operator and corresponding device

摘要

A device comprises a chip storing a first subscription relating to the first mobile network operator in a home country. The chip stores a second subscription relating to a second mobile network operator and associated with a preferred communication technology. The chip receives location information and analyses whether an extended cell identity value is present within the location information. The chip detects, based upon the analysis, a currently available communication technology relating to a second mobile network. The chip compares the currently available communication technology to at least one preferred communication technology. If the currently available communication technology matches at least one preferred communication technology, then the chip switches to a second subscription associated with the preferred communication technology. The chip sends to the device at least one identifier relating to the second subscription related to the second mobile network.
