System and methods for increasing efficiency of a public land mobile network search in service acquisition on a multi-SIM wireless device

A wireless communication device, comprising:

• a first radio resource associated with a first subscriber identification module (SIM);
• a second radio resource associated with a second SIM;
• and
• a processor coupled to the first and second SIMs and respective first and second radio resources, wherein the processor is configured to:
• detect a condition triggering a public mobile land network (PLMN) selection associated with the first SIM;
• receive an indication that service acquisition settings of the first SIM are set to a manual mode;
• determine whether a modem stack associated with the second SIM is in idle mode;
• and
• in response to determining that the modem stack associated with the second SIM is in idle mode:
• identify timing of a power-saving mode cycle implemented by the modem stack associated with the second SIM;
• and
• perform a PLMN search using the first and second radio resources.

• receiving an indication that service acquisition settings of the first SIM are set to a manual mode;
• determining whether a modem stack associated with a second SIM is in idle mode, wherein the second SIM is associated with a second radio resource;
• and
• in response to determining that the modem stack associated with the second SIM is in idle mode:
• identifying timing of a power-saving mode cycle implemented by the modem stack associated with the second SIM;
• and
• performing a PLMN search using the first and second radio resources.
