I got Moto E815 a few days ago. Even if I was not going to do IM, I downloaded Mobile IM, just out of curiosity. Registered ID and password, explored the software, and ... when I checked my account info, it said I sent and received over 30 text messages! I didn't chat with anybody at all. I have never used text message service.

Today I found out every single exchange of data between the cell phone and the server is charged. Logging in, getting the buddy list, etc. This is crazy. Even the tech department did not know this and kept saying I (or somebody else) did "chat" using my phone. After this call, I found out the fact from a web site.

Does everyone know this?
