Every SIM card has several attributes that the network uses when communicating with the mobile phone: IMEI number, SIM number, Additional Services Indicator (ASI), ICC/ICCID, and SIM PIN. For a time the AT&T network used a 12-digit Mobile Identification Number (MIN) format. AT&T later changed to an 15-digit format. SIMs work like the ATM cards from a bank, with the network card embedded in the mobile device, and use a unique code to identify the SIM. SIMs also be contained within a SIM card reader for computers or VoIP handsets for direct connection.
Encryption scrambles a message to make it unreadable. Two or more different encryption schemes (encryption types) may be used on a particular communication, providing a different cipher key for each. A key is a secret number, word, or other symbol that is used in cryptograpy. Some keys have to be shared between the communicating entities for the cryptographer to correctly analyse the encrypted message. In GSM, both encryption and scrambling are performed by the network. The mobile phone and the service provider have no access to the key, however. The radio protocol is designed to prevent eavesdropping so that only the intended recipient can decipher the encrypted message.
Complete list of serial numbers can be obtained through the process of discovery. Deciding to search for the serial number is when you want to know if it is legit. Inventing a serial number is when you want to find out if any given retail copy is legitimate but not an official/manufactured copy.
is the serial number search not working for the 11700? I've tried it and it keeps asking for a serial number. (and it would be awesome if EA would really know what they are doing when putting in weird areas).. 7211a4ac4a
