How to Retrieve the IMSI

By Jacob Stover

IMSI stands for International Mobile Subscriber Identity; it is an identification code used to individually represent cell phones on the GSM and UMTS networks. IMSI is associated almost exclusively with Android-based cell phones, and is the functional equivalent to IMEI and MEID codes used across different cell networks to identify telephony-equipped electronic devices. Retrieving your IMSI is a fairly straightforward task regardless of the operating system your phone uses, and it should take no more than five minutes to learn and complete.

Things You'll Need

  • Mobile phone

Using Android OS

Step 1

Open the app drawer, then open the "Settings" app.

Step 2

Tap "About Phone" from the settings menu.

Step 3

Tap "Status," then scroll down to the IMSI heading. Your IMSI number will be listed below this heading.

Using Symbian or Palm OS

Step 1

Power up your phone.

Step 2

Ensure that your phone has service, and that it is not in airplane mode.

Step 3

Dial "*#06#" on the keypad, then press "Send." Your phone should display its IMSI number after a short delay.
