Note that the mobile user will receive the first message e.g. “Atif has sent you a Web 2 SMS chat message. If you wish to receive the messages from Mak, please reply Y. To reject, please reply N”. In case of reply with Y the session will start – otherwise it won’t. Once a session starts you can send and receive messages.
For those mobile users who do not use text messaging often this may be a surprise! This may not work with all handsets and this service can be blocked by the mobile users.
This functionality is available at many websites which connect to the mobile company’s gateway. I prefer going to the mobile provider site as much as possible so that I may avoid the clutter and ads at the other sites. Here are the links for sending such messages for other providers.
