Straight Talk SIM in T-mobile Samsung Galaxy S3 phone unable to download pic msgs or send pics.

I have a Straight Talk SIM that I put into a Tmobile Samsung Galaxy S3 phone. I'm unable to download pic msgs or send pics. I've spent hours with the guy at the phone store going through countless APNs that aren't fixing the problem. Please help!
