What is SIM unlocked?

In the United States, AT&T (Cingular) and T-Mobile use GSM networks to operate. So the equipment they provide to customers are GSM phones, PDA's and other mobile devices which operate on their GSM networks. GSM phones are designed to be used with SIM cards (small plastic smart cards which fit into the back of your phone). These SIM cards typically carry customer account information such as the carrier, mobile numbers, and other details which allows the phone to recognize the network and user in order to provide service. Without an active SIM card, a GSM phone will not work.

Most U.S. GSM carriers such as AT&T (Cingular) and T-Mobile get their phones from manufacturers such as Motorola, Samsung, Nokia, etc. When the phones arrive in the U.S., they are repackaged, software flashed, and SIM locked by intermediate companies before they are available to customers. SIM locked means that there is a software or hardware lock which allows the phone to only be used with a particular carrier which it is locked for. So for example, this which you cannot buy a Cingular phone and use it for T-Mobile.

The phones we sell here at Daddiyo are all SIM unlocked. So you can use them with ANY GSM carrier around the world. In addition, we sell only tri-band or quad-band GSM phones so they are typically compatible internationally. The U.S. will use 850/1900 mHz GSM networks and Asia/Europe will use 900/1800 mHz GSM networks. Tri-band and quad-band phones have a combination of 3-4 bands which makes them compatible with international GSM networks when travelling.

Note: U.S. carriers like Verizon Wireless and Sprint work on CDMA networks and Nextel works on iDEN networks. Therefore, GSM phones will not work on these networks.
