I'm with T-mobile and I live in an area where I always have signal (at least 4 bars), but over the last 2-3 days whenever I leave my phone(motorola defy) in my pocket, then get if out after a couple of hours to check it, it says emergency calls only, even when it's got full battery...

does anyone know how to fix this? as I can't receive any calls or texts when it does this and is really frustrating.

thanks, Mushroom.
