The IMEI number is the unique identifier for each handset (whether a Blackberry or any other handset) Every network has the ability to block this number thus rendering the handset useless. Unlike a blocked SIM card, the IMEI number is blocked by the network, rather than the individual handset, and once blocked, this renders the handset useless - changing the SIM will have no effect !
Firstly, AT&T is spelt with an '&' symbol. Secondly, if your purchased your iPhone from the online Apple Store, the handset will already be unlocked and you can use any service with the handset. However if you purchased the handset on a network service plan, you will need need to contact your service provider.
Provided its a micro sim and the handset is not locked and the provider actually provides a service for the iPhone 4S then there should be no problem.
You will need to contact your service provider and inform them you do not wish their services and to allow you to unlock your handset from their network. Depending on your circumstances, like if you are under a contract there may be a fee payable to the service provider to have the handset unlocked. You will find that haandsets can be bought from the manufacturer unlocked and free from any network but usually no matter what the company or provider, costs for unlocked versions of any mobile phone are always more costly to purchase if you are buying the handset brand new. Suppliers initially will not always sell unlocked products at the launch of a product and if they do as mentioned they charge high sums to purchase one unlocked.
ALL carriers use a SIM card !... The SIM card identifies the individual handset - and allows the service provider to charge the user for any calls, texts or downloaded data.
Since IMEInumber is unique, it will help us in locating your lost or stolen mobile handset. For now, note down this IMEI number and keep in a safe place. You can also find your mobile IMEI number on your mobile handset packet cover.When you switch on our mobile phone, your mobile SIM card tries to connect with any available network. Once it finds a supported network it tries to build a network connection between your mobile handset and the nearest tower. During this connection negotiation, your SIM transfers some internal information to the network operator such as your mobile IMEI number, mobile model, version etc. This means your mobile operator keeps the record of your mobile handset number each time you try to switch on your mobile handset and use their service.Now if you have lost your mobile handset or your phone has been stolen, you can contact your network provider to block your IMEI number. They might ask you to get a Police FIR copy first, do as they say and finally ask them to block your IMEI number. Mobile network providers use a shared hosting service for blocking IMEI numbers, which means if you have asked network 'Airtel' to block your mobile handset, it automatically gets blocked by network 'VodaFone', 'Reliance', 'Idea Cellular' and so on.Now when that thief will switch on your mobile handset, no service providers will allow it to build any connection with them. It does not matter if he changes the mobile SIM card, since SIM card requests for the service with IMEI number and a blocked IMEI number handset will be ignored and the mobile will become an useless toy.
