I've noticed when I leave the house and I'm not on Wifi, 3G doesn't work. And when I try to use it I get a message that theres no cellular data for my phone or something like that. I should have taken a picture but I didn't. I have the data turned on under settings, and it tells me what network and everything I'm on. I have roaming off for obvious reasons, but even switching it on doesn't work. Any ideas? Everyone else on my plan works fine. Verizon.
