Roaming charges question

[ron4543]

Hi, I have a 1st gen iPhone jb on 2.2 with T-Mobile and am away from home for the week. My phone has no T-Mobile service where I am but since it was configured to auto detect networks it picked up AT&T here. I know that if I make calls or use the internet I will be charged accordingly but I was unsure about texting. I currently have the unlimited texting plan so normally I just get my regular bill but I didn't know if they would count as data while roaming. I checked on T-Mobile's website and couldn't find anything definitive but was hoping that someone here may have the answer. Thanks in advance.

You shouldn't be charged at all if you're roaming as far as I know.
