The embodiments of the invention provide a small-amount phone fee payment method, device and system. The method includes the following steps that: a payment module responds to a payment request initiated by an application in a terminal and sends a first payment process request to a server end, wherein the first payment process request includes a first parameter and a second parameter; the payment module receives an payment operation process and corresponding parameters returned by the server end according to the first parameter and the second parameter; the payment module initiates a second payment request for an operator or a third party payment platform according to the payment operation process and the corresponding parameters so as to make the operator or the third party payment platform respond to the second payment request and send a payment result to the server end; the payment module initiates a payment result query request to the server end; and the payment module receives the payment result and sends the payment result to the application in the terminal. The method can be better compatible with a payment operation process which is not set in advance, the payment module does not need to be re-integrated and encapsulated, and therefore, maintenance and updating cost can be reduced.
