ShMessenger Mobile is a free instant messaging client for mobile phones, which supports YMSG (Yahoo!) protocol. In just a few minutes, you can chat with your friends on Yahoo! Messenger, from your mobile phone.
Which version should I install?
ShMessenger Platinum is the last version of the application, supported only by the newer phones (MIDP 2.0, color display - minimum 65,000 colors). There are two builds available for "Platinum" version: simple keyboard (for phones with numpad) and full keyboard (for QWERTY, QWERTZ and similar keyboards).
Gold version has simpler graphics, but it is almost as ergonomic as "Platinum" version. It is recommended for phones which have smaller color depth displays.
Mobile (MIDP-2.0) version uses the native controls of the phone, thus the memory usage is lower. It is recommended for the phones which have less processing power and/or RAM.
Mobile (MIDP-1.0) version is deticated to MIDP-1.0 phones.
Requirements
For Gold version, internet connection is required.
ShMessenger Platinum, Mobile(MIDP-2.0) and Mobile(MIDP-1.0) can connect through either internet or wap. However, the generated traffic when using wap connection is higher. Due to this fact, connecting through wap is only recommended for users who have an unlimited wap traffic plan.
If you have activated one of these services, all you need to do is create an account in My account section, download and install the application.
