My simless iPhone still says it has service. Why? 
What carrier? Verizon or Sprint?
- Why does my old iPhone still have service? I activated my new iphone and when i turn on my old iphone it still says "Verizon" at the top left hand corner. Why is this? I already activated my new iphone and all the calls go to my new phone so why does the old one still have service?
- My iPhone 4s says no service I've had it about 4 months and it's been working just fine until this morning. It's now been a couple of hours where it's told me no service and has refused to let me call or send messages. I tried turning it on and off several times and I've been moving around all morning so it isn't lack of reception. It's getting really frustrating, please help me! Is there anything I can try?
- My iphone says i'm connected to Wi-Fi but when i try to run something it says i'm not connected? My phone shows signal, it has a check mark by the device but when i try to open an app it says can't find a connection.
- My iPhone says device blocked from network service how do i fix it? I took my AT&T simcard out of my white iphone4 and put it into a newly restored, black iphone4, started it up, and then put the simcard back in my white iphone4. Now when i try to text, it fails, and the calls just say: device blocked from network service: how do i fix this?
