I need a basic chat application.
The app has to be in Java so that it is supported by all phones that support Java.
User have to download the app and use their mobile number to register. User can then add others by adding thier mobile number within the application.
If both users are online then they can chat with each other for free.
The app also has to have a chatroom, the chatroom will have basic catogaries. User need to pay to enter the chatrooms. I intend to charge users by getting them to send an sms, using their credit card and by third party payment system, thus the app has to integrate with the payment systems.
Simple, easy to use chat application is what i need.
