METHOD AND APPARATUS TO HAVE MORE SIM CARDS THAN CELLULAR MODEMS AND ASSIGN THE SIM CARDS TO THE MODEMS AT RUN TIME

摘要

A hardware and software design that allows a device to have more SIM cards than modems and assign the SIM cards to these modems at run time. In addition the method can use information received from an external entity, like a server residing on the internet for example, with information about preferred network operator. Another exemplary decision making is based on trial: a device can test several SIM cards from different network operators, and select the set of SIM cards that exhibit best performance.
