IMEI track or blocking

[choudang]

Dear All,

I have lost my handset (Nokia E50) couple of days back and now i want to block the handset. is it possible to do so, if yes, how to do that.

There is a one site where can register our mobile no along with IMEI no so that it will send the SMS to registered mobile no if SIM got changed, but I am not able to recall the site name.

Reply appreciated

Thanks

Want to block phone? Forget it.
For this, you need cooperation from service provider, which you won't be able to get.
