I'm having a weird problem, I just got a charge off someone and upgrading from a 3g phone. Went and got the 4g sim and activated everything. Data works and can get on the internet and everything, but when I try and make a phone call, it says "no network available". I flashed a stock image, took to Verizon (they had no idea and couldn't fix it go figure) did all the software updates and still no luck. I have never seen or heard of this issue. Any one ever heard of this or have any ideas of what the issue might be?
