CHECK IT: This app works differently depending on which version of Android you have:
1. If your phone runs Android earlier than 4.0.3 (Ice Cream Sandwich), your data and picture messaging settings will be updated automatically.
2. If your phone has 4.0.3 or anything newer then the app will help you get the most accurate instructions for your phone.
Just download this App and follow the step-by-step instructions to program Data and Picture Messaging settings automatically for your SIMPLE Mobile Android.
If you're a nerdy type you can cut right to the chase and skip installing this app altogether. Just go right to the instructions here: APN Support Center http://www.mysimplemobile.com/Support-Center-Phone-Programming.aspx
