No signal or data all of a sudden

[Chris+Wainwright]

No data or signal - error message showed saying no sim. I have reset network settings and this hasn't helped. Searched postcode in Nuneaton area and seems there isn't an issue in the area?

It could be a faulty sim if rebooting the device doesn't fix it then you will have to find away to get in touch with Sky so they can get a replacement one sent out to you via Royal Mail.
