How to configure Straight Talk MMS picture messaging for iPhone?

Before configuring Straight Talk MMS picture messaging in your iPhone, make sure you have already got the internet connectivity/wireless data setup properly. I have already posted on How to setup Straight Talk Wireless Data or Internet Connection on iPhone?

Now if you want use MMS picture messaging, you need to configure your MMS APN settings in your iPhone. Its really easy to edit the APN settings by going to the Settings tab in iPhone. But the problem is that, I have seen many users complaining that they cannot see the Cellular Data Network settings in their iPhone. Now this happens because when you have the Straight Talk AT&T SIM in your iPhone, the Cellular Data Network settings gets hidden. We have a hack called SIM Swap Method to overcome this.

To do the SIM swap, you need a T-Mobile network SIM (it doesn’t need to be a active SIM). The Cellular Data Network settings will be visible when you put the T-Mobile SIM in your iPhone. Now you quickly put the Straight Talk AT&T SIM back in and enter the Cellular Network Data settings before the option disappears. Once you get the settings tab then its pretty easy to just edit the apn settings. If you have bought the StraightTalk SIM kit with three SIM cards, then you the Pink SIM is for the T-Mobile network. For the iPhone 4 models a micro SIM and for the iPhone 5 a nano SIM is required.

  • After this remove your StraightTalk AT&T SIM from your iPhone and insert the T-Mobile SIM.

  • Now remove the T-Mobile SIM card and again insert your StraightTalk SIM card.
  • The Cellular option will be grayed out now. Wait until it is available. Tap Settings -> General -> Cellular -> Cellular Data Network

  • Turn your iPhone off and restart it again. (Make sure you fully power down and not simply make it to sleep)
  • Now turn off the WiFi and try loading some websites in Safari to check if the data connection is still working.
  • From Home Screen, Tap Settings->Messages-> iMessage Off
  • Try sending a friend an MMS and verify that you don’t get any error message. You can also ask your friend to send you a picture message to verify that your MMS picture messaging is working perfectly.If Data and MMS work, then kudos, you have succesfully configured Straight Talk internet connection/wireless data and mms in your iPhone. Don’t forget to turn on your WiFi and iMessage later.

    I have an old straight talk sim which works with the above settings, but since I updated to ios 7, I can no longer receive mms.

    Whenever I change the mms setting to att.mvno it auto reverts back to tfdata. Is there a workaround or fix?

    Any thoughts?
