Over-the-air primary and companion user device interactions

One or more non-transitory computer-readable media of a primary user device storing computer-executable instructions that upon execution cause the primary user device to perform actions comprising:

• receiving a termination command from an over-the-air (OTA) platform of a wireless carrier network to terminate a short-range wireless communication link with a companion user device;
• terminating a short-range wireless communication with the companion user device in response to the termination command to trigger the companion user device to establish a cellular communication link with the wireless carrier network;
• initiating a countdown of a predetermined time period at the primary user device for the companion user device to receive an OTA update from the OTA platform via the cellular communication link;
• and
• in response to the countdown indicating that the predetermined time period has elapsed, reestablishing the short-range wireless communication link with the companion user device to trigger the companion user device to terminate the cellular communication link.

A computer-implemented method, comprising:

• receiving, at a primary user device, a termination command from an over-the-air (OTA) platform of a wireless carrier network to terminate a short-range wireless communication link with a companion user device;
• terminating, at the primary user device, a short-range wireless communication with the companion user device in response to the termination command to trigger the companion user device to establish a cellular communication link with the wireless carrier network;
• initiating, at the primary user device, a countdown of a predetermined time period at the primary user device for the companion user device to receive an OTA update from the OTA platform via the cellular communication link;
• and
• in response to the countdown indicating that the predetermined time period has elapsed, reestablishing, via the primary user device, the short-range wireless communication link with the companion user device to trigger the companion user device to terminate the cellular communication link.
