The present invention generally provides systems and methods for performing money transfer transactions via a wireless communication device, such as a cellular phone. In accordance with the invention, the wireless communication device is associated with, or automatically linked to, at least one payment source account (i.e., the wireless communication device is associated with a payment source account that may be automatically charged for payment of account balances, authorized charges, and/or money transfers). In a preferred embodiment, the wireless communication device is associated with at least one pre-paid payment source account. In one example, the wireless communication device is a pre-paid cellular phone and/or is associated with a pre-paid money transfer account. In certain aspects, the wireless communication device may access a pre-directed phone number, e.g., *55, to access a money transfer service provider. Once connected to a money transfer service provider, a user may initiate a money transfer via the wireless device, which is optionally paid to a payee in-person at a money transfer service provider location.
