A system, method and computer program for ordering, paying for and download digital products to a mobile device in a cost-effective manner. The mobile device includes a short range transceiver and a network transceiver. The mobile device accesses electronic shop server web sites which contain digital products for sale and hotspot network locations where these digital products may be downloaded to the mobile device via the short range transceiver. The hotspot network locations contain a hotspot device for transmitting the digital products to the mobile devices via the low power radio frequency signal of the short range transceivers when the mobile device has detected the low power radio frequency signal. Using this system, method and computer program, a user of a mobile device may download large amounts of digital data without incurring telephone or cellular phone charges.
