Multiple SIM multiple network diversity for enhancing call connectivity

A multi-subscriber identity module (SIM) communication device, comprising:

• a processor configured with processor-executable instructions to:
• determine whether a quality of a first call between a calling party and a called party using a first SIM associated with a first one of a plurality of network subscriptions for a first network is degrading;
• provide network alternatives for establishing a second call in response to determining that the quality of the first call is degrading;
• select one of the network alternatives based on an order of suitability for establishing the second call, wherein the selected one of the network alternatives comprises a second SIM associated with a second network;
• and
• notify the called party using information associated with the calling party and the second call before the second call is originated, the information associated with the second call identifying the calling party to the called party before the second call is originated,
• wherein the processor is configured with processor-executable instructions to notify the called party by sending a short message service (SMS) to the called party on the second network including the information associated with the second call.

A non-transitory computer readable storage medium having stored thereon processor-executable instructions configured to cause a processor of a multi-subscriber identity module (SIM) communication device to perform operations comprising:

• determining whether a quality of a first call between a calling party and a called party using a first one of a plurality of network subscriptions for a first network is degrading;
• providing network alternatives for establishing a second call in response to determining that the quality of the first call is degrading;
• selecting one of the network alternatives based on an order of suitability for establishing the second call, wherein the selected one of the network alternatives comprises a second SIM associated with a second network;
• and
• notifying the called party using information associated with the calling party and the second call before the second call is originated, the information associated with the second call identifying the calling party to the called party before the second call is originated, wherein notifying the called party comprises sending a short message service (SMS) to the called party on the second network including the information associated with the second call.
