Why can't I send or receive pics?

I recently switched my iPhone from AT&T to straight talk and now I can't send or receive pictures.

You need to change some setting within the phone to get internet and picture messaging to work.

  • Why can't i send or receive text messages? I have an Iphone 3Gs, and just recently I have not been able to send or receive text messages from one contact. When I try sending a message it says "received" but when we talk through facebook or anything else they inform me that they never got the message, and its the same with their phone, I never get the messages. Its becoming a big hassle and I just want the problem fixed. Can anyone help me out?

  • Why can't my iPhone send or receive pictures in text messaging? My dad bought me the iPhone 4S unlocked. I got the prepaid service at tmobile which was 50$ unlimited talk text and web. I can't send pictures during text messages and I can't receive them. If someone sends me a picture I don't get it, it's just blank. The little camera icon next to the text area to type is light grey indicating I can't press on it. I can only send or receive during iMessage. Please tell me why this is happening.
