Opportunistic dual SIM dual active operation in multi-subscriber identity module devices

A user equipment (UE) comprising:

• a first subscriber identity module (SIM) associated with a first service provider subscription and a second SIM associated with a second service provider subscription;
• and
• a processor configured to access the first SIM and the second SIM, the processor further configured to:
• camp on a first cell associated with a first technology in standalone mode using the first service provider subscription;
• search a database having a plurality of entries identifying a plurality of cells, associated available technologies of the plurality of cells, and availability of standalone mode, wherein searching the database includes prioritizing ones of the entries indicating availability of standalone mode;
• select, from the entries, a second cell associated with a second technology in standalone mode;
• and
• camp on the second cell, using the second service provider subscription, concurrently with camping on the first cell.
