I wrote this guide to share with you how I set up my data/internet connection and MMS picture messaging on my Nokia Lumia 920 running Windows Phone 8. While this guide shows how I set up my Nokia Lumia 920, I would expect it would work with other Nokia Lumia models or Windows Phone 8 smartphones.
For this guide, I expect you have an active Straight Talk Wireless SIM inserted into your phone. Your voice calls and SMS text messages show work already work. Your cellular data and MMS picture messaging will not work until you configure your phone.
I created this guide using a Nokia Lumia 920 and a Straight Talk AT&T compatible SIM. I was using one of the new Straight Talk SIMs so my phone gets 4G LTE service.
