Abstract

The present invention discloses methods and systems for selecting at least one SIM card for data communication at a wireless communication device which is capable of housing a plurality of SIM cards. When a switching condition is satisfied, the wireless communication device selects a second SIM card group, and disconnects one or more connections established using any non-second group SIM card. Non-second group SIM cards are SIM cards that are not in the second SIM card group. A selected SIM card from the second SIM card group is then used for data communications. The steps are repeated until (i) the switching condition is no longer satisfied, (ii) no more SIM cards selected from the second SIM card group can be used for data communications or (iii) no more connection is made using non-second group SIM cards.
