My sister is having an issue with her Droid. I had rooted and custom ROMd it for her, she's really not technical or anything. Anyway, she receives email fine, but when she tries to place a call she gets a message that the Mobile Network is not available. I thought it was maybe some service outage (she's in NY, I'm in FL), but she is able to make calls with my mom's phone (which is a dumbphone, if that matters). Any ideas? Tried searching google for that message but didn't find anything. Is it just a temporary service outage? I assume it can't be the phone since she's still getting emails and other data stuff. it's just the phone calls that are down...
