So I just setup my Nexus 4 on Straight talk via an AT&T sim card. Calls are fine, data is fast, everything appears to work EXCEPT the Play Store? Im using the APN in this post, the first one. I didnt have data until I created this APN and gave it a "Blue" circle (aka, checked it). http://androidforums.com/nexus-4/649586-here-how-make-mms-work-straight-talk-att-nexus-4-a.html Any ideas how to fix this?
