My phone will decide out of no where to stop making or receiving calls, and the same goes for text. I have turned it off and on, taken the battery out, factory restarted it, and even called for tech support, but nothing i do keeps this problem from reoccurring. Then the next day my phone will go back to working, like nothing ever happened. this is the second droid x of mine to do this, the first one got sent back for the same reason, and they sent me this one, that does the same thing. If anyone has some advice i am all ears.
