T-Mobile AIM cost?

[Wix]

Hello... I have T-Mobile and it has the feature to use AIM or not. I also have the plan to send Unlimited Messages... So my question is if I use AIM and sense each IM I recieve counts as an IM... will I have any other charges on my bill if I start to use AIM (since I have unlimited text) Thank you!
