How to Retrieve the IMSI

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.
