How to Find IMSI on Android: A Complete Step-by-Step Guide

Every mobile device connected to a cellular network has identifiers that help the network recognize the device or subscriber. One of these identifiers is the IMSI, or International Mobile Subscriber Identity.

If you are troubleshooting a SIM connection, working with mobile network information, or simply trying to understand how cellular identification works, you may want to know how to find the IMSI on Android.

However, unlike the IMEI, the IMSI is not always displayed directly in Android's standard Settings menu. Its availability can also vary depending on the Android version, device manufacturer, SIM configuration, and carrier.

This guide explains what an IMSI is and several legitimate ways to check whether your Android phone exposes this information.

What Is an IMSI?

IMSI stands for International Mobile Subscriber Identity. It is a unique identifier associated with a mobile subscription and stored on the SIM or eSIM profile.

An IMSI is generally made up of three components:

• MCC (Mobile Country Code): Identifies the country or geographic region associated with the mobile network.
• MNC (Mobile Network Code): Identifies the mobile network.
• MSIN (Mobile Subscriber Identification Number): Identifies the subscriber within that network.

The IMSI is primarily used by cellular networks for subscriber identification and authentication.

IMSI vs. IMEI

IMSI and IMEI are often confused, but they identify different things.

Identifier	What it identifies
IMSI	Mobile subscriber/SIM subscription
IMEI	Physical mobile device
ICCID	SIM card or eSIM profile

A phone can have the same IMEI while its associated IMSI changes when the SIM or mobile subscription changes.

Why Would You Need to Find Your IMSI?

Most Android users never need to access their IMSI directly. However, it can be relevant in certain technical situations, such as:

• Troubleshooting cellular connectivity
• Testing mobile network configurations
• Diagnosing SIM-related issues
• Working with authorized mobile network systems
• Learning about cellular network technology
• Checking subscriber information during technical support

Because the IMSI is a sensitive network identifier, you should avoid sharing it publicly or with untrusted applications.

How to Find IMSI on Android

There isn't one universal method that works on every Android phone. Try the following options depending on your device and Android version.

1. Check Your Android Settings

Some Android devices expose SIM-related information through the Settings application.

The exact menu names can vary by manufacturer.

Start by opening:

Settings → About Phone → Status / SIM Status

Look for information such as:

• SIM status
• Network
• Phone number
• Mobile network
• SIM information

Some devices may display an identifier related to the SIM or subscription, while others may not show the IMSI at all.

Why Isn't IMSI Always Visible?

Modern Android versions restrict access to sensitive subscriber information. Therefore, even when your phone technically has an IMSI, the operating system may not display it to the user.

If you cannot find it in Settings, that does not mean your SIM does not have an IMSI.

2. Check SIM Card Information

Another option is to look at the SIM information available through your phone's mobile-network settings.

Depending on your Android device, you may find it under:

Settings → Network & Internet → SIMs

or:

Settings → Connections → SIM Manager

Samsung and other manufacturers may use different menu structures.

You may see details such as:

• SIM name
• Carrier
• Network type
• SIM status
• Mobile network
• Phone number

Again, the IMSI itself may not be displayed.

3. Use Android Diagnostic or Testing Menus Carefully

Some Android devices provide diagnostic or testing interfaces containing additional cellular information.

These menus are primarily designed for troubleshooting and technical testing. Their availability depends on the device manufacturer, Android version, and carrier.

If your device provides an official diagnostic interface, use it only for viewing information and avoid changing network parameters unless you know exactly what they do.

Changing advanced network settings unnecessarily can cause connectivity problems.

4. Use a Trusted SIM Information Application

Some applications can display information associated with the SIM and mobile network.

However, this approach requires caution.

An application that claims to display IMSI may request permissions that provide access to sensitive device or network information. Before installing an app, check:

• Developer reputation
• App reviews
• Requested permissions
• Privacy policy
• Recent update history
• Whether the app actually needs access to your SIM information

Modern Android security restrictions may also prevent third-party applications from accessing the IMSI, even when an app claims that it can.

For this reason, an app may show your carrier, SIM state, or network type without being able to display the actual IMSI.

5. Ask Your Mobile Carrier

If you need the IMSI for a legitimate technical or support-related reason and your Android device doesn't expose it, contacting your mobile carrier may be the most appropriate option.

The carrier manages the subscriber information associated with your mobile account and can explain what information is available to you.

When contacting support, explain why you need the information rather than attempting to bypass Android's security restrictions.

Can You Find IMSI Using a Dialer Code?

You may find websites claiming that a particular USSD or dialer code will display the IMSI on every Android phone.

There is no universal code that reliably exposes the IMSI across all Android devices and carriers.

Dialer codes can vary by:

• Carrier
• Country
• Device manufacturer
• Android version
• Cellular technology

Some codes may open diagnostic information, while others may simply do nothing.

Avoid entering unknown service codes found online, particularly if they are intended to modify network settings rather than display information.

Why Android May Hide the IMSI

The IMSI is different from information such as your phone model or screen resolution. It is associated with your mobile subscription and can be considered sensitive subscriber information.

Android has progressively tightened access to sensitive identifiers through its permission and security model.

As a result, applications may be unable to retrieve certain subscriber identifiers unless they have the appropriate privileges or are operating in an authorized context.

This is one reason older tutorials may no longer work on newer Android devices.

How to Find IMSI on Samsung Phones

Samsung devices use the company's One UI interface, so the location of SIM information may differ from stock Android.

You can generally start by checking:

Settings → About phone → Status information

You can also check:

Settings → Connections → SIM manager

The exact options can vary by Samsung model, One UI version, SIM configuration, and carrier.

If IMSI is not shown, use the carrier-support method rather than attempting to bypass the device's security controls.

How to Find IMSI on Google Pixel Phones

On Google Pixel devices, start with:

Settings → About phone → SIM status

You can also explore:

Settings → Network & internet → SIMs

The available information depends on the Pixel model, Android version, SIM or eSIM configuration, and carrier.

If the IMSI isn't displayed, your device may simply restrict access to that identifier.

IMSI on Physical SIM vs. eSIM

The way mobile subscriptions are represented has changed with the adoption of eSIM technology.

A physical SIM contains subscriber information associated with the mobile subscription. An eSIM stores the corresponding subscription profile digitally.

The important point is that IMSI is associated with the mobile subscription rather than simply being a permanent identifier of the phone itself.

Therefore, changing SIMs or activating a different mobile subscription can result in a different IMSI even though the Android phone remains the same.

Is It Safe to Share Your IMSI?

It is generally better to treat your IMSI as private information.

You should avoid posting it on:

• Public forums
• Social media
• Screenshots shared publicly
• Untrusted websites
• Unknown technical-support channels

If a legitimate carrier or authorized technical-support professional asks for subscriber information, verify that you are communicating through an official channel.

Also be cautious of websites or applications promising to reveal someone else's IMSI. Accessing another person's subscriber information without authorization can violate privacy and telecommunications laws.

IMSI, IMEI, and ICCID: Quick Comparison

These three identifiers are related to mobile connectivity but serve different purposes.

IMSI

Identifies the mobile subscriber or subscription on the cellular network.

IMEI

Identifies the physical mobile device.

ICCID

Identifies the SIM card or eSIM profile.

For example, if you replace your SIM card but keep the same phone, the IMEI generally remains associated with the phone, while the SIM-related identifiers can change.

What If Your Android Phone Doesn't Show the IMSI?

Don't worry if none of the methods above display your IMSI. This is increasingly common because Android and device manufacturers restrict access to sensitive subscriber identifiers.

If you need the information for a legitimate purpose, consider these options:

1. Check your phone's official SIM-status information.
2. Review documentation supplied by your carrier.
3. Contact your mobile provider.
4. Use authorized diagnostic tools provided by your organization or carrier.
5. Avoid attempting to circumvent Android's security restrictions.

Frequently Asked Questions

Can every Android phone display the IMSI?

No. IMSI visibility varies according to the Android version, device manufacturer, carrier, SIM configuration, and system permissions.

Is IMSI the same as IMEI?

No. IMSI identifies a mobile subscription, while IMEI identifies the mobile device.

Can I find IMSI without a SIM?

A traditional physical-SIM IMSI is associated with a mobile subscription. With eSIM, the subscription profile is stored digitally. Without an active mobile subscription, there may not be an IMSI available to view through the device.

Can an Android app always read the IMSI?

No. Android's security and permission restrictions can prevent ordinary applications from accessing sensitive subscriber identifiers.

Should I share my IMSI online?

It's best not to share your IMSI publicly. Treat it as sensitive subscriber information and only provide it to trusted, authorized parties when necessary.

Final Thoughts

Finding the IMSI on Android isn't always as straightforward as finding the IMEI. While some devices may expose SIM or subscriber information through their settings, newer Android versions can restrict access to sensitive identifiers.

Start by checking your phone's SIM Status or SIM Manager sections. If the IMSI isn't available, don't attempt to bypass Android's security protections. For legitimate technical requirements, your mobile carrier or an authorized support provider can help determine what information is available.

Most Android users don't need their IMSI for everyday tasks. Understanding the difference between IMSI, IMEI, and ICCID, however, can make troubleshooting SIM and mobile-network issues much easier.
