Generally described, one or more aspects of the present application correspond to techniques for dynamic management of the network used for data transfer between a connected vehicle and a remote computing system. For example, during navigation a connected vehicle may switch between connections to a number of different networks, and the pricing of these networks may be periodically recalculated based on current network load. The disclosed techniques can select from among available networks to dynamically optimize the cost of data transfer, even as a vehicle navigates through different networks and as network pricing is changed.
