"No Service" on my iPhone 4, for the past two days.

[Klif]

Hi, I've been a Fido customer for almost two years now, with an iPhone 4, and have up to now had no complaints or trouble with the service. However, since Tuesday my phone has had no phone or 3G service ("No Service" in the top left of the screen). I have only had access to data or iMessage through Wifi. My account is not showing any outstanding payments or any reason why I might have been disconnected, so I am assuming this is either a mistake at Fido's end or a problem with my phone. Can anyone help?

Is your iPhone jailbroke?

If not eject your sim from the phone and put it back in with the phone on and wait a minute to see if it activates on the network you may have to turn the Airplane mode on then off as well to kick it in

If its jailbroke try removing any recent packages installed
