Update Sept 22 2103
This guide is for iOS 6. I have a new guide for iOS 7. See How to Setup Straight Talk Wireless Data and MMS for your iPhone running iOS 7. Both guides should work for iOS 7, but try the new one, I have tried to improve the process and well as update the screen shots for iOS 7.

Many readers are reporting problems that they are having trouble sending or receiving MMS over the last few days. If you are having a problem please leave a comment here: I Can’t Receive MMS Picture Messages Using Straight Talk or Net10 on My iPhone Using iOS 7.0.4
This guide describes how to set up Straight Talk Access Point Name or APN for Data, Internet, MMS, or picture messaging for your iPhone. I documented the steps I used to set up my iPhone 5 with Straight Talk Data and MMS. This guide should help you with any iPhone 3GS, iPhone 4, iPhone 4s, or iPhone 5 running iOS 6. The guide shows step by step how to setup the Access Point Name or APN values needed to data and MMS picture messaging working.
If you have been using Straight Talk with your iPhone and your data or MMS has suddenly stopped working, try this post.
If you are using an Android phone or smartphone other than an iPhone, this guide is not for you. Please try my generic smartphone guide.
If you are looking to switch your iPhone to Straight Talk, see the article I wrote about my experience.
