I was used my phone for a while and it was working just fine. Then when I wanted to use it later my phone said I didn't have service. I figured I just had to turn it on and off for it to go back to normal but that didn't work. I can't make any calls or texts and my monthly service hasn't even expired yet, so I don't know how to get it to work again. All it says it "Looking for Service" but it doesn't find anything.
