Question about AT&T Texting

Alright guys, here's the story.

I'm a little preoccupied with fear at the moment to do any sort of Google search. My girlfriend is over in Germany for a month taking classes, and she hasn't been taking it too well. Hasn't eaten or slept for two days now.

So I decided to just forget about the texting bill and have her text as much as she wants (they're only giving her 10 minutes of internet a week).

I'm on AT&T and she's on TMobile. My question is, does texting to her TMobile number give any international text messaging rates for me?

Her number's technically not an international number. It's a TMobile US number, so the answer is no right?

Thanks in advance!

 

Thanks for the quick response!
