Maintaining access to services via SIM card

A first device, comprising:

• a memory;
• and
• one or more processors configured to:
• determine that a first subscriber identity module (SIM), previously used by the first device, is not available for use by the first device;
• determine that a second SIM is available for use by the first device within a predetermined time period after the first SIM is determined to be not available for use by the first device;
• and
• store data that allows the first device to access, while the first SIM is unavailable for use and the second SIM is available for use, at least one service in association with a communication identifier of the first SIM.

A non-transitory machine-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• determine that a first subscriber identity module (SIM), previously used by a first device, is not available for use by the first device;
• determine that a second SIM is available for use by the first device within a predetermined time period after the first SIM is determined to be not available for use by the first device;
• and
• store data that allows the first device to access, while the second SIM is available for use, at least one service in association with a communication identifier of the first SIM.
