Classification: CPC H | IPC H

Claim 11:
12. A cellular router, comprising:
a plurality of subscriber identification module SIM interfaces;
a plurality of wireless communication module (WCM);
at least one processing unit;
at least one non-transitory computer-readable storage medium storing program instructions executable by the at least one processing unit for:
a. receiving an information request from a WCM;
b. determining whether a first response information corresponding to the information request is stored in a storage unit; wherein the first response information is generated by a Universal Integrated Circuit Card (UICC) or an Embedded Universal Integrated Circuit Card (eUICC) based on the information request; wherein the UICC or the eUICC is housed in a massive SIM apparatus (MSA);
c. when the first response information corresponding to the information request is not stored in the storage unit:
i. forwarding the information request to the MSA;
ii. sending a first WCM response to the WCM after received a second response information; wherein the second response information corresponds to the information request from the MSA; wherein the first WCM response is generated based on the second response information;

d. when the first response information corresponding to the information request is stored in the storage unit:
i. retrieving the first response information from the storage unit; wherein the first response information corresponds to the information request;
ii. sending a second WCM response to the WCM; wherein the second WCM response is generated based on the first response information;

wherein the cellular router communicates with the MSA through at least one interconnected network; and
wherein the WCM is housed in the cellular router or is located with the cellular router in the same premise.
