Phone got wet. Won't turn on, but once every 5-8 days, and then it won't load up, it just sits on the Verizon (in my case) picture, and "freezes" up so to speak, and nothing will change, (can't turn off even)unless I take battery out.. Then, won't turn on again for 8-10 days... or so. I want my PHONE numbers from it-- is there a SIM card? Do i need to unscrew the back to find it? I have an identical phone that works, so i just hope i can switch out the SIM cards, and my numbers will be there...???
