Methods and systems for data communication at a primary wireless communication apparatus in conjunction with an auxiliary wireless communication apparatus
The present invention discloses methods and systems for data communication at a primary wireless communication apparatus (WCA) in conjunction with an auxiliary WCA. The primary and the auxiliary WCAs may be connected and each houses at least one subscriber identification module (SIM). When a data packet is to be sent using the primary WCA, a wireless communication module (WCM) of the primary WCA is used. When a data packet is to be sent using the auxiliary WCA, a WCM of the auxiliary WCA is used. When receiving a data packet, the data packet is processed based on the receiving WCA. When a data packet is received through the WCM of the primary WCA, the data packet is processed at the primary WCA. When a data packet is received through the WCM of the auxiliary WCA, the data packet is first sent to the primary WCA and then processed.

(c) at the auxiliary WCA, determining whether a first criterion is met;
(d) at the auxiliary WCA, performing a first action when the first criterion is met; and
(e) at the auxiliary WCA, performing a second action when the first criterion is not met;
wherein the first criterion is not determined based on cellular signal strength; and
wherein steps (c) and (d) are performed by the auxiliary WCA after step (a) is performed by the primary WCA.

wherein the auxiliary WCA comprises:
at least one second processing unit;
at least one second SIM interface;
at least one second WCM; and
at least one second non-transitory computer readable storage medium storing program instructions executable by the at least one second processing unit for:
(c) determining whether a first criterion is met;
(d) performing a first action when the first criterion is met; and
(e) performing a second action when the first criterion is not met;
wherein the first criterion is not related to cellular signal strength; and
wherein steps (c) and (d) are performed by the auxiliary WCA after step (a) is performed by the primary WCA.
