Tool usage guide
The IMSI Validator is a precise utility designed to verify the structure of International Mobile Subscriber Identity (IMSI) numbers and extract key network information, including the Mobile Country Code (MCC) and Mobile Network Code (MNC).
Background
An engineer needs to verify which carrier a specific SIM card belongs to based on its IMSI.
Problem
Manually looking up MCC/MNC codes is slow and prone to human error.
How to use
Enter the 15-digit IMSI into the validator to instantly extract the MCC and MNC components.
Outcome
The tool confirms the MCC and MNC, allowing the engineer to identify the specific mobile network operator.
Background
A database contains a list of subscriber records with potentially malformed IMSI entries.
Problem
Incorrectly formatted IMSI numbers cause provisioning failures in the core network.
How to use
Input the IMSI strings into the validator to check for correct length and numeric structure.
Outcome
Invalid entries are flagged for correction, ensuring only properly formatted IMSI numbers are processed.
An IMSI is a unique 15-digit number used to identify a mobile subscriber on a cellular network.
No, all validation occurs locally or in-session, and your data is not stored or logged.
No, this tool is specifically for IMSI numbers, not MSISDNs or public phone numbers.
The tool will flag the input as invalid if it fails the length check or contains non-numeric characters.
Yes, it supports global IMSI formats by identifying the MCC/MNC codes assigned by the ITU.
