Messaging became so popular with the advent of internet that provides services like MSN, Yahoo etc. As technology advanced, this messaging was possible even through mobile phones. When internet and Java are enabled in mobile devices, it became very easy to make and send instant messages. The only problem is its small screen and the inability to type messages quickly. But, QWERTY function and large screens have made it easier. But instant messaging through internet has helped internet service providers to charge us for the service. Agile Messenger that required Symbian OS was widely used, but it not free now.
"My Friends" and "My Presence" are some of the services that were brought in for mobile phones as chat clients based on wireless village technology. The major setback of this service is the polling system which it is based on. That is, we have to connect to the server frequently and check out for status of the contacts online. Here, the messages that are sent do not become 'instant'. Setting up smaller intervals for polling will not be sufficient and will result in huge cost for its usage.
A very few of them are aware of such services. It is because, most of the mobile phone manufacturers or service providers do not make use of these clients built in phones. Yamigo or SmartVAS are certain free services where you can run Wireless Village in the background and use it with any other application. These services have their own disadvantages like you will have to add every person with online status if you wish it to be notified in Yamigo or SmartVAS contact list.
The Jabber technology is another one that connects multiple instant messenger networks concurrently. It has a server as well as a client. Here, the server stores the username and password, while the user has to login using a jabber client. Those phones that have MIDP1.0 do not have TCP socket that supports jabber clients.
E-Messenger is also a popular method where you require a mobile that supports internet and has a WAP browser. The login screen does not remember your sign in name and if you have to make use of any other feature of the phone, the WAP browser has to be closed. This is a major setback of this service.
In future, it is hoped that such services will be dropped and there will be a 24/7 static IP internet connection in mobile phones where we do not require to type in our user name and password to a third party. The services that were explained above are absolutely free of charge, but let's hope to find out a solution that covers all its disadvantages.
