A method for obtaining data at an electronic communication device enables transmission of data in response to a ring back tone. The method comprises transmitting from the electronic communication device to a network a call setup signal for a call to a callee device (step 205). A ring back tone associated with the callee device is then processed at the electronic communication device, wherein the ring back tone is received from the network in response to the call setup signal (step 210). A data request signal then transmitted, in response to the ring back tone, from the electronic communication device to the network (step 215). Data that are received from the network in response to the data request signal are then processed at the electronic communication device (step 220).
