Are using your iPhone with Straight Talk Wireless? Does the error “Could not activate cellular data network. You are not subscribed to a cellular data service” pop up when you try to use cellular data? Do you see “Not Delivered“ in red when sending MMS picture messages? If so, keep reading because this article will help you.

This article shows you how to set up Straight Talk Wireless’ Access Point Name (APN) on your iPhone. You must set your APN to:

• access the internet using your cellular data connection
• send and receive MMS picture messages
• send and receive group text messages

These instructions are for iPhones using Straight Talk’s AT&T compatible SIM card or Straight Talk’s TMobile compatible SIM card. I created these instructions using my iPhone 6 with iOS 8.x installed. The instructions will work for iPhones using iOS 8 including:

• iPhone 6 Plus
• iPhone 6
• iPhone 5s
• iPhone 5c
• iPhone 5
• iPhone 4s

The instructions should also work for iOS 7, but the screenshots and steps might be a little different. If you are using the latest version of iOS 7, I’d say try this article rather than the older one. My older articles for iOS 7, How to Setup Straight Talk Wireless Data and MMS for your iPhone running iOS 7

If you are using iOS 6, see How to Setup Straight Talk Wireless Data and MMS for your iPhone running iOS 6

Disclaimers

This article will not fix your iPhone if you cannot:

• place phone calls
• receive phone calls
• send SMS text messages
• receive SMS text messages

or if your iPhone uses

• Straight Talk’s CDMA Verizon compatible network
• Straight Talk’s CDMA Sprint compatible network

For either of these cases, stop reading and see Problems With Your iPhone’s APN for Data and MMS on Straight Talk’s Verizon Network

Setting up your APN

I divided this article into six parts. You only need to read the parts that are relevant for you.

1. Finding and Removing Your iPhone’s Straight Talk Configuration Profile
2. Looking up Your Straight Talk Wireless APN Settings
3. Setting up Straight Talk Wireless tfdata APN on Your iPhone
4. Setting up Straight Talk Wireless att.mvno APN on Your iPhone
5. Setting up Straight Talk Wireless wap.tracfone APN on Your iPhone
6. Verifying Your iPhone’s Cellular Data Connection, MMS Picture Messages, and Group Text Messages

Follow part 1 and part 2 above. You only need to follow part 3, 4, or 5 for your specific APN which you looked up in part 2.
