Abstract: A system and method may provide an exchange service for providing the price of wireless minutes to wallet applications and other client applications. The system may obtain pricing information for the wireless minutes and provide the pricing information to a wallet application. The pricing information may be provided through a rate server that subscribed to receive the pricing information. The rate server typically also provides exchange rates for currencies for use at wallet applications that are communicably coupled to the rate server. By providing the pricing information to wallet applications, wireless service providers may variably price their wireless services. End users may be able to obtain real-time prices of the wireless services and purchase such services directly using payment accounts associated with a wallet application. For example, a Bitcoin wallet may be used to obtain real-time prices of the wireless services and purchase such services using Bitcoins.
