Overview

The IMSI Generator is a specialized utility designed to create valid International Mobile Subscriber Identity (IMSI) numbers. By utilizing standard Mobile Country Codes (MCC) and Mobile Network Codes (MNC), this tool allows developers and network engineers to generate realistic subscriber identities for testing and simulation purposes.

When to Use

  • •When you need to populate test databases with valid subscriber identity formats.
  • •When simulating mobile network registration or authentication workflows.
  • •When developing software that requires specific MCC/MNC combinations for carrier identification.

How It Works

  • •Specify the quantity of IMSI numbers you need to generate.
  • •Enter a 3-digit MCC or 2-digit MNC if you require specific carrier or country codes.
  • •Leave the MCC and MNC fields blank to allow the tool to generate random, valid combinations.
  • •Click generate to receive a list of formatted IMSI numbers ready for your application.

Use Cases

Software testing for mobile network billing and provisioning systems.
Generating mock data for telecommunications research and analytics projects.
Simulating subscriber behavior in virtualized mobile core network environments.

Examples

1. Generating Test Data for China Mobile

Network Engineer
Background
The engineer is setting up a test environment for a new HLR (Home Location Register) interface.
Problem
Need a batch of valid IMSI numbers specifically associated with China Mobile (MCC 460, MNC 00).
How to Use
Set quantity to 10, enter 460 for MCC, and 00 for MNC.
Example Config
quantity: 10, mcc: 460, mnc: 00
Outcome
A list of 10 unique IMSI numbers starting with 46000, ready for system integration testing.

2. Randomized Subscriber Simulation

QA Tester
Background
Testing a mobile application's ability to handle diverse subscriber identities from different regions.
Problem
Need a variety of IMSI numbers to ensure the application correctly parses different MCC/MNC combinations.
How to Use
Set quantity to 50 and leave MCC/MNC fields blank for randomized output.
Example Config
quantity: 50
Outcome
A list of 50 varied IMSI numbers with randomized country and network codes for comprehensive validation.

FAQ

What is an IMSI?

An IMSI (International Mobile Subscriber Identity) is a unique number used to identify a user on a cellular network, typically stored on a SIM card.

Can I generate IMSIs for specific countries?

Yes, you can specify a 3-digit Mobile Country Code (MCC) in the configuration to restrict the output to a specific region.

Are these IMSI numbers real?

These numbers follow the standard structure and use valid MCC/MNC codes, but they are generated for testing and simulation purposes only.

How many IMSIs can I generate at once?

You can generate up to 100 unique IMSI numbers in a single request.

What happens if I leave the MCC and MNC fields blank?

The tool will automatically assign random, valid MCC and MNC codes to the generated IMSI numbers.
