I could not find if anyone already asked this here before but..

I have the unlimited data plan from T-Mobile and have to pay for each SMS text message sent/received. So I started using Google Talk after the nighmare it was to get my bill after using OZ Messenger.

But just to make sure, I contacted T-Mobile through email to have them confirm that since Google Talk uses data to transmit messages, and because I have the unlimitted data plan, that I should not get any extra charges on my bill. So I just got their answer and they say that I will still get charged for ever message. I told them to double check everything because it makes not sense.

Is there anyone out there who's got the same set up as I do and has been using Google Talk without having to pay for every message?
