Embodiments are disclosed for handover between wireless carriers in multiple devices. In an example configuration, an in-vehicle computing system of a vehicle includes a first network interface configured to communicate over a first wireless carrier, a second network interface configured to communicate over a second wireless carrier, a processor configured to control communication via the first network and the second network, and a storage device storing instructions executable by the processor to connect to a computing device over the first wireless carrier. The instructions are further executable to send a select message to the computing device via a remote server, the select message identifying the second wireless carrier, receive a confirmation message from the computing device initiating communication over the second wireless carrier, and receive data from the computing device over the second wireless carrier.
