Mobile device communication system

A method and system to conduct financial transactions over a communication network is provided. Data associated with a mobile communication device user is received and stored, and a user mobile airtime account is allocated to the user. A purchase request is received from the user via a mobile communication device, the purchase request being for a purchase from a merchant for a purchase amount. The communication network provides the user access to the network to make the purchase request without debiting a financial account of the user or the user mobile airtime account for the access to the communication network. A payment service provider now automatically debits the financial account of the user with the purchase amount, automatically allocates a service fee which is associated with the purchase amount to the mobile service provider and credits an account of the mobile service provider with the service fee. The payment service provider also automatically credits an account of the merchant with at least a portion of a remainder of the purchase amount.
