How i do block my stolen nokia e63 - Nokia E63 Cell Phone

The best way to do block your mobile phone is to make sure you have kept the box or at least, have written down the IMEI number.
Provided you have those details, you should be able to contact your service provider, or the phone company itself if the provider cannot help, and they will be able to block your phone.
The blocking may not restrict all uses of the phone itself, but it will be more or less 'bricked', meaning no signal for any reason what so ever as well as maybe requiring a PUK upon removal of the sim. I hope this helps. Good luck.
