1. A method for selecting at least two SIM cards at a wireless communication device, wherein the wireless communication device is configured to house a plurality of SIM cards, the method comprising:
using the at least two SIM cards simultaneously to establish a plurality of connections;
determining whether a switching condition is satisfied; and
when the switching condition is satisfied:
(a) selecting a substitute SIM card from the plurality of SIM cards based on at least one factor;
(b) disconnecting a corresponding connection established by one of the at least two SIM cards, wherein the corresponding connection is in the plurality of connections;
(c) determining whether the substitute SIM card is capable of transmitting and receiving data;
(d) using the substitute SIM card to establish a substitute connection after the substitute SIM card is determined to be capable of transmitting and receiving data;
(e) repeating steps (a) to (d) until (i) the switching condition is no longer satisfied or (ii) no SIM card is selected based on the at least one factor;
wherein the plurality of SIM cards is classified into a plurality of groups according to the at least one factor; and
wherein the at least two SIM cards are from two different groups in the plurality of groups.
