In a technique for enhancing discoverability and increasing usage of a web browser in a mobile device on a wireless network, a server system coupled to the wireless network receives a signal representing initiation of a voice call from the mobile device. In response, the server system performs a lookup to determine whether a website is associated with the telephone number being called. If a website is associated with the telephone number being called and the mobile device has the capability to access and display the website, the server system sends an Alert to the mobile device, causing the mobile device to notify its user about the website. The user may then input a selection to either access the website instead of completing the call or to proceed with the voice call.
