A computer-implemented method and system for providing Unstructured Supplementary Service Data (USSD) services is provided. The computer-implemented method comprises the steps of configuring a cross-operator USSD module for receiving one or more service requests sent to a cross-operator number by one or more communication devices associated with one or more telecommunication service providers. The cross-operator USSD module further processes the one or more service requests for generating one or more interactive USSD menus based on information retrieved from the one or more service requests and one or more pre-defined rules. Furthermore, the cross-operator USSD module renders the one or more interactive USSD menus on the one or more communication devices, wherein the one or more interactive USSD menus facilitate one or more users of the one or more communication devices to avail the USSD services.
