When it comes to identifying and connecting your mobile phone to the network, there are several important numbers to consider. In this article, we will explore the IMEI, IMSI, ICCID, and MSISDN numbers and their significance in the world of mobile technology.

IMEI Number: Your Mobile Phone’s Identity
Let’s begin with the IMEI number, which stands for International Mobile Equipment Identity. This unique 15-digit code is assigned to the SIM card slot inside your mobile phone. To locate your IMEI number, simply dial “*#06#” on your phone’s dial pad, and the number will be displayed.
IMSI Number: The Secret Identifier
The IMSI, or International Mobile Subscriber Identity, is a number assigned to the SIM card or the mobile subscriber. The IMSI is a confidential number, kept hidden for your own protection. Mobile networks often use a temporary IMSI called the Temporary Mobile Subscriber Identity (TMSI) for communication purposes. The IMSI consists of 15 digits, with the first three digits representing the Mobile Country Code (MCC), the next two digits representing the Mobile Network Code (MNC), and the remaining ten digits representing the Mobile Subscriber Identity.
ICCID Number: Identifying Your SIM Card
The ICCID, or Integrated Circuit Card Identifier, is assigned to the hardware portion of your SIM card. It is a 19 to 20 digit number that can be broken down into four parts. The first part is the industry code, followed by the country code and network issuer’s code. The last digits are unique identifiers for individual SIM cards.
MSISDN Number: Your Mobile Phone Number
The MSISDN, or Mobile Station International Subscriber Directory Number, is your full mobile phone number, including the country code and all the prefixes. For example, if you have a SIM card from a UK-based mobile operator, your MSISDN number will start with “+44” because the telephone code for the UK is “+44” or “0044.”
