Abstract: A chip is coupled to a device. The device stores at least one configuration parameter for configuring an access to an Internet type network. According to the invention, the chip stores data relating to at least two subscriptions. The method comprises the following steps. The chip de-activates a first subscription. The chip activates a second subscription. The second subscription is distinct from the first subscription, as a previously active subscription. The second subscription is a currently active subscription. The chip detects whether the device does or does not read a currently active subscription. Only if the device reads a currently active subscription, then the chip detects whether at least one configuration parameter does or does not allow accessing an Internet type network. Only if at least one configuration parameter does not allow accessing an Internet type network, then the chip ascertains that at least one configuration parameter is corrupted.

Abstract: 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.
