System and methods for improving recovery from an out-of-service state by SIMs of a multi-SIM device based on user activity

A wireless communication device, comprising:

• a radio frequency (RF) resource configured to connect to at least one of a first subscriber identity module (SIM) and a second SIM;
• and
• a processor coupled to the RF resource and configured with processor-executable instructions to:
• detect that at least one of a modem stack associated with the first SIM and a modem stack associated with the second SIM is in an out-of-service state;
• determine whether the modem stacks associated with the first and second SIMs are both in the out-of-service state;
• and
• in response to determining that the modem stacks associated with the first and second SIMs are both in the out-of-service state:
• determine whether a voice call or an active data communication session was dropped by the modem stack associated with the first or second SIM upon experiencing a loss of service;
• and
• prioritize service recovery on the modem stack corresponding to the dropped voice call or active data communication session in response to determining that a voice call or an active data communication session was dropped by the modem stack associated with the first or second SIM.

A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor of a wireless communication device having a radio frequency (RF) resource associated with at least one of a first subscriber identity modules (SIM) and a second SIM to perform operations comprising:

• detecting that at least one of a modem stack associated with the first SIM and a modem stack associated with the second SIM is in an out-of-service state;
• determining whether the modem stacks associated with the first and second SIMs are both in the out-of-service state;
• and
• in response to determining that the modem stacks associated with the first and second SIMs are both in the out-of-service state:
• determining whether a voice call or an active data communication session was dropped by the modem stack associated with the first or second SIM upon experiencing a loss of service;
• and
• prioritizing service recovery on the modem stack corresponding to the dropped voice call or active data communication session in response to determining that a voice call or an active data communication session was dropped by the modem stack associated with the first or second SIM.
