Samsung Captivate & Straight Talk..... HELP!!!!!

[paposseracing75]

Ok here we go. My wife purchased a samsung captivate AT&T from c'slist and trying to use straight talk.
Model #SGH-I897. She called AT&T & got the unlock code. Activated it with the straight talk sim card.
She can call and text, but NO internet & pics. I am assuming that the sim card is T-Mobil, as there was no other
offer. Please can someone help us?????? Many THANKS in advance.........
