A method of caching communications for devices being transported by vehicles includes receiving, at a vehicle via a forward link, a message directed to the vehicle and a plurality of other vehicles. The message includes: (i) content to be delivered to a requesting mobile computing device being transported by the vehicle or one of the plurality of other vehicles, and (ii) an indication of at least some of the content to be cached in one or more computer readable storage media disposed on the vehicle. The method further includes determining if the requesting mobile computing device is being transported by the vehicle, and, if the requesting mobile computing device is being transported by the vehicle, forwarding at least some of the content to the requesting mobile computing device. At least some of the content is then stored on the one or more computer readable storage media disposed in the vehicle based on the indication of the least some of the content to be cached.
