I have a iphone 4s.
The internet service is running but no coverage: not let me make or receive calls or sms.
Can anyone help?
talk to your wireless carrier.
First you can try to fix it by yourself.
Check here: Settings > Carrier.
And Settings > Messages.
If this not worked. Restart iPhone.
And if that not worked > Restore iPhone via iTunes > Set up iPhone as new user.
That doesnt work, I had tried before.
