Inside a SIM card

Staying connected with loved ones is very important. Therefore, it is necessary today to know your SIM card well. This article teaches you about the functionality of a SIM card, ways to purchase it and the steps to order your postpaid SIM.

 

How does a SIM card work?

Every mobile phone needs a SIM card to connect the user to a mobile network.

 

A SIM card is an integrated circuit or an IC chip that securely stores the IMSI integrated mobile subscriber identity number and a key that are used to identify the subscriber and connect them to a mobile network via the mobile phone or a computer.

 

A SIM card contains:

 

  • International mobile subscriber Identity Number (IMSI)
  • Security authentication and ciphering information
  • Temporary local network information
  • List of services availed by the subscriber
  • 2 passwords: Personal Identity Number (PIN), Personal Unblocking Code (PUC)

 

Without the SIM card you cannot connect to a mobile network, although you can only dial 999, for security reasons.
