Virtual subscriber identity module for mobile communication device

A wireless communications device comprising:

• a modem, and
• one or more processors outside of the modem,
• the wireless communications device configured to perform steps comprising:
• receiving, from a local communication network, a first authentication request for a subscriber identity module (SIM);
• responding to the first authentication request by locally resolving the first authentication request using a first simulated SIM, wherein the first simulated SIM is a SoftSIM and is associated with a foreign SIM profile not corresponding to a subscription to the local communication network;
• establishing a data communication link via the first simulated SIM;
• loading profile information for a second simulated SIM associated with a local SIM profile corresponding to a subscription to the local communication network, wherein the second simulated SIM is a VirtualSIM;
• receiving, from the local communication network, a second authentication request for the second simulated SIM;
• relaying the second authentication request to a first remote server via the established data communication link;
• receiving an authentication response to the second authentication request from the first remote server via the established data communication link;
• and
• responding to the second authentication request with the received authentication response,
• wherein the steps are performed using a driver running on the modem and a simulator running on the one or more processors.

A non-transitory computer-readable media (CRM) comprising instructions that, when executed by one or more processors of a wireless communication device, cause the wireless communication device to perform steps comprising:

• receiving, from a local communication network, a first authentication request for a subscriber identity module (SIM);
• responding to the first authentication request by locally resolving the first authentication request using a first simulated SIM, wherein the first simulated SIM is a SoftSIM and is associated with a foreign SIM profile not corresponding to a subscription to the local communication network;
• establishing a data communication link via the first simulated SIM;
• loading profile information for a second simulated SIM associated with a local SIM profile corresponding to a subscription to the local communication network, wherein the second simulated SIM is a VirtualSIM;
• receiving, from the local communication network, a second authentication request for the second simulated SIM;
• relaying the second authentication request to a first remote server via the established data communication link;
• receiving an authentication response to the second authentication request from the first remote server via the established data communication link;
• and
• responding to the second authentication request with the received authentication response,
• wherein the instructions cause the steps to be performed using a driver running on a modem included in the wireless device and a simulator running on the one or more processors.
