Managing data communications based on phone calls between mobile computing devices

A computing system comprising:

• at least one processor;
• and
• at least one communication unit configured to receive a first notification from a first mobile computing device and a second notification from a second mobile computing device,
• wherein the at least one processor is configured to determine, based at least in part on a comparison of the first notification to the second notification, that the first mobile computing device has initiated a phone call with the second mobile computing device, and
• wherein responsive to the at least one processor determining that the first mobile computing device has initiated the phone call with the second mobile computing device, the at least one communication unit is configured to:
• send a first message to the first mobile computing device using a first data connection;
• and
• send a second message to the second mobile computing device using a second data connection,
• wherein the first message and second message each indicate that the first and second mobile computing devices are able to exchange application data.

A computer-readable storage medium that storing instructions that, when executed, cause one or more processors to:

• receive a first notification from a first mobile computing device and a second notification from a second mobile computing device;
• determine based at least in part on a comparison of the first notification to the second notification, that the first mobile computing device has initiated a phone call with the second mobile computing device;
• and
• responsive to determining that the first mobile computing device has initiated the phone call with the second mobile computing device,
• send a first message to the first mobile computing device using a first data connection, and
• send a second message to the second mobile computing device using a second data connection,
• wherein the first and second messages each indicate that the first and second mobile computing devices are able to exchange application data.
