Papaya turns your phonebook into a fun and useful social network! It allows you to communicate with your friends cheaply and easily, no matter where you are. Using Papaya, you can play games with your friends, chat with them over IM, share pictures and other files, make cheap international calls, and more.
Papaya has three parts: an application to be installed on your cell phone, a mobile website (WAP site), and a website where you can sign in.
You can use Papaya on wap.papayamobile.com without downloading anything. However, if you need to use some of the advanced features such as phonebook synchronization or playing java games, you will have to download the Papaya application and install it on your cell phone.
