Question about Samsung SGH-E370 Cellular Phone
I recommend you contact your service provider.
Blacklisted or Barred Handsets
What is it all about???
A phone may be blacklisted (or barred) for many different reasons, but the most common reason is that it has been reported either lost or stolen! It is only the networks (Orange, T-Mobile, O2, Vodafone etc) that have the facility to blacklist a handset.
If you are unfortunate enough to either lose or even worse have your phone stolen you should report it to your service provider (your network) immediately!
Your service provider can then blacklist the handset so that it can no longer be used to make or receive any calls. The networks do this by adding your phones serial number onto a national blacklist database (Central Equipment Identity Register). Effectively the handset becomes absolutely useless and the thief is in possession of a pretty paper weight! :-))
So How Does Blacklisting Work?
Every mobile phone has a unique serial number. This serial number is called the IMEI number (International Mobile Equipment Identity). It can normally be found underneath the phones battery and it is 15 digits long.
Now each time you switch your phone on or attempt to make a call the network systems check the IMEI number of the handset you are using. At this point the IMEI number of your handset is cross referenced with the Central Equipment Identity Register. If the IMEI number of your handset is on the CEIR then the network will either:
1) Refuse to send a signal to your phone (No signal strength at all)
2) OR WILL supply a signal but will not allow any outgoing or
If your IMEI number is on the CEIR your handset is blacklisted and therefore useless.
