How to Check SIM Details: A Complete Guide
In today’s digital world, a SIM (Subscriber Identity Module) card is more than just a tool for making calls or sending messages—it’s the key to accessing mobile data, verifying identity, and using essential services. Whether you’re switching devices, ensuring your SIM is registered under your name, or verifying an unknown number, checking SIM details has become increasingly important.
In this article, we’ll explore how to check SIM details in different ways, across various regions and devices.
Why You May Need to Check SIM Details
Before diving into the methods, here are some common reasons why you might want to check SIM information:
- To verify SIM ownership or registration.

- To check the network provider.
- To confirm if the SIM is active.
- To recover lost numbers or avoid SIM fraud.
- To track SIM card history in case of misuse.
1. Check SIM Details via USSD Codes
USSD (Unstructured Supplementary Service Data) codes are short codes that you can dial from your phone to get information directly from your mobile network provider.
Here are some common USSD codes used in different countries:
India
- Airtel: Dial *121# → Choose “My Account”
- Jio: Use the MyJio app or call 198
- Vi (Vodafone Idea): Dial *199#
- BSNL: Dial *123#
Pakistan
- Jazz: Dial *99# – Shows SIM number
- Zong: Dial *8# or *100#
- Telenor: Dial *8888#
- Ufone: Dial *780*3# or *1#
These codes typically show your number, balance, and sometimes additional info like data usage or plan.
2. Using Mobile Carrier’s Official App
Most telecom companies offer mobile apps that allow you to check complete SIM details including:
- Owner’s name
- Mobile number
- Plan or package
- Data and call usage
- SIM status (active/inactive)
Examples:
- MyAirtel, MyJio, MyVi, My BSNL (India)
- Jazz World, My Zong App, My Telenor, Ufone App (Pakistan)
Steps:
- Download the app from Google Play Store or App Store.
- Register or log in using the SIM number.
- Navigate to the account/profile section to view full details.
3. Check SIM Owner Name Online
Some countries offer online SIM information systems for safety and transparency. These portals help you check which SIMs are registered under your name or CNIC (Computerized National Identity Card).
Pakistan (PTA SIM Information System)
- Visit: https://cnic.sims.pk
- Enter your CNIC number
- Complete captcha verification
- You’ll get a list of all SIMs registered under your CNIC, along with the mobile network.
Note: This helps ensure no unauthorized SIM is issued under your identity.
4. Contacting Customer Care
If other methods don’t work, you can always call your telecom provider’s customer care number to ask for SIM details:
- Be ready to verify your identity (name, CNIC, DOB, etc.)
- Customer support can help you:
- Check ownership details
- Verify activation date
- Provide SIM status
- Assist with reissuing a SIM or blocking it if lost
5. Phone Settings (Basic SIM Info)
Your smartphone can also show some SIM details directly from settings.
For Android:
- Go to Settings > About Phone > SIM Status
- You can see:
- Network name
- SIM number (sometimes)
- IMEI
- Signal strength
- Roaming status
For iPhone:
- Go to Settings > General > About
- Scroll down to see ICCID (SIM card number), Network, and Phone Number

6. Third-Party Apps
There are several apps that help users get additional SIM info, like:
- SIM Card Info
- SIM Details – Device & Network Info

Important: Use trusted apps only. Avoid apps that ask for unnecessary permissions or seem suspicious.
7. SIM Tool Kit (STK App)

To use:
- Look for the SIM Toolkit app in your app drawer.
- Open it and explore the menu to find your number or other SIM-related services.
Safety Tips While Checking SIM Details
- Always verify SIM registration under your own name.
- Avoid sharing SIM or CNIC details publicly or with untrusted apps.
