What is a SIM card?
SIM stands for Subscriber Identity Module. The SIM card is a tiny memory chip card which has information stored on it. Your mobile phone reads the information in your SIM card when it connects to the mobile phone network and may also use it to save information such as your phone book. The network uses the SIM card to identify the user of a mobile phone and needs this information for billing purposes. Because the “identity” of the user is contained in the SIM card and not in the mobile phone, you can use the same SIM card in another mobile phone and retain the same mobile phone number. Often, SMS messages are also stored in the SIM card.
A sim card is a small flat rectangle plastic that contains a microchip. This microchips is the heart of your phone, it contains your phone number, your address book, and the necessary information for your phone to work. All sim cards look the same, but the microchip inside is different for every GSM service provider.
SIM stands for Subscriber Identity Module. A SIM card is a small “smart card” for GSM/GPRS mobile phones that contains your personal account profile as well as saves important information (i.e. network information, account services, your mobile phone number, stored telephone numbers, SMS messages and more). The SIM card must be inserted in the handset in order for it to operate.
Short for Subscriber Identify Module, it is used to register the calls placed and received while in a GSM coverage area. SIM cards are non-transferable between devices. Customers must use the SIM card in the device that it comes packaged with only. Customers are not permitted to have a MTS SIM card without the Motorola A840. Any SIM card transferred to another device or tampered with will not be guaranteed or provided support service by MTS.
