Switched from Straight Talk T-mobile sim to AT&T sim and now my Moto X doesn't work
I have been using Straight Talk since February 2014. I was using the AT&T sim in my Galaxy S2, and about 1 month ago I bought a new Moto X phone (unlocked). I put the Straight Talk T-mobile sim card in and that worked right away without any issues for about 1 month. A few days ago, I decided to switch back to AT&T, because I got better cell service at my house when I used AT&T with my Galaxy S2; however, after I went through the process to switch, my phone no longer works.
I should clarify that it sometimes allows me to make/receive a phone call or pull up a webpage, but about 5 minutes later it stops working again and shows no reception or 4G. I have been on the phone with Straight Talk at least 7 times, and they just have me turn my phone on and off and reset the APN settings. Nothing works. I've even resorted to trying to use my husband's extra AT&T nano sim to see if that would work, and it is the same thing. This is the third sim card I have tried with no resolution (2 x AT&T and 1 T-mobile).
