So I just received the N4 today! However, I'm having issues setting it up... this is my first Android device and if this is posted else where I apologize. So I put the new AT&T activated sim in my phone and I have access to voice. But, I can't get any MMS or internet I read this article, How to set up the right APN on your Nexus 4 | Android Central, that says if you are on post-paid it should just work... Is this a APN related issue or am I missing something? I appreciate any assistance thanks.
