Does logging onto messenger on my cell phone cost extra money?

Question

I have Cingular, I have the option of aim/yahoo/msn.

Answer 1

Every message you send or receive using your IM software counts as a text message. So, either you have a pool of txt msgs to use up per month, you're paying per msg of you don't have a package, or both.

Yes, the act of logging onto your AIM/Y!M/Windows Live Messenger account costs one txt msg. So get ready to use up a lot of txt msgs.
