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.
