I have a moto g, and it went in for service in Jan 31/14. The original problem was that the sim card wouldn't lock into place. slide the card in, it would "click", but could still slide it out with your fingernail. And after getting it back from service, the problem still persists. Having to open the back of the phone a couple of times a week is getting to wear on my nerves a little, and not having service when I need it is not acceptable.
