When someone calls you from a number you don’t know, you want to know who it is and whether it’s safe to answer. In Pakistan, unknown or spam calls are very common, and sometimes these calls can even be linked to scams or fraud. Knowing the SIM owner details and SIM information can help you stay safe and protect your privacy.
In this guide, you’ll learn what SIM owner details are, how SIM registration works in Pakistan, how to check SIM information, and how TrueCallID can help you identify unknown callers quickly. Everything is explained in simple English so anyone can follow along.
What Are SIM Owner Details and SIM Info
SIM owner details refer to the official information of the person who owns a registered SIM card. In Pakistan, every SIM must be registered with a valid CNIC, and the owner details include the person’s name, CNIC number, and other registration information.
SIM info covers additional data such as the network provider, SIM activation date, and the total number of SIMs registered under a CNIC. Together, SIM owner details and SIM info help you identify who is behind a number and ensure your SIMs are registered correctly.
Why SIM Information Matters in Pakistan
In Pakistan, SIM verification and ownership checks are more than just convenience — they are a form of protection.
Fraud and spam protection: Many people receive spam calls or messages pretending to be from banks or companies. Checking SIM ownership helps identify if a number is legitimate or suspicious.
Preventing identity misuse: Sometimes, people use another person’s CNIC to register multiple SIMs. This can lead to serious problems if those SIMs are misused. Checking how many SIMs are registered under your CNIC helps prevent such issues.
Verifying registration accuracy: Over time, old or inactive SIMs may still be registered under your name. Regular checks let you remove numbers you no longer use.
Legal and safety reasons: If you need to report harassment, scams, or threats, having the correct SIM ownership details helps you provide accurate information to authorities.
Business or personal verification: For small businesses and freelancers, verifying numbers of clients or vendors adds trust and professionalism.
How SIM Registration Works in Pakistan
SIM registration is controlled by the Pakistan Telecommunication Authority (PTA). Every new SIM must be registered to a valid CNIC, and the process includes biometric verification.
When you buy a new SIM, you show your CNIC at an authorized franchise or retailer. Your fingerprint is verified through the biometric system, and your data is linked to your CNIC in the PTA database. This ensures that every SIM in Pakistan has a verified owner.
You can also check how many SIMs are registered under your CNIC by sending your ID number to the official PTA verification service via SMS or by using trusted online platforms.
If you find an unrecognized SIM registered under your name, you can visit your mobile network franchise to deactivate or transfer ownership. Keeping your SIM registration data accurate helps protect your identity and prevent misuse.
What Information You Can Check
When you use a SIM information service, you can find several useful details.
When checking by mobile number:
Registered owner’s name
Mobile network operator (Jazz, Zong, Ufone, Telenor, etc.)
Activation or registration date
SIM status (active or inactive)
Number of SIMs linked to the same CNIC
When checking by CNIC:
Full name of the CNIC holder
Network providers of all active SIMs
Total number of SIMs registered under that CNIC
Status of each SIM (active or inactive)
Keep in mind that some services only show limited information for privacy reasons. For example, you might only see how many SIMs are registered under your CNIC without revealing exact numbers or names.
How to Check SIM Owner Details and SIM Info
Checking SIM owner details or SIM info in Pakistan is simple and can be done in a few ways. Here’s how.
Checking how many SIMs are registered under your CNIC:
Type your 13-digit CNIC number (without dashes).
Send it to the official verification service (668).
You’ll receive an SMS showing how many SIMs are registered under your CNIC, along with the network names.
If you find SIMs you don’t recognize, visit your mobile network franchise and request deactivation.
Checking the owner of a mobile number:
Write down the number you want to check.
Visit a trusted SIM info or caller ID platform.
Enter the mobile number in the search bar.
The system will show available information such as the registered name and network.
Using the TrueCallID app:
TrueCallID is Pakistan’s top caller ID application. It identifies unknown numbers by showing names and sometimes photos of people calling you.
Download the app from a trusted app store.
Register using your number.
When you get a call, the app instantly identifies who’s calling.
You can also manually search numbers within the app to verify identity.
If you find unauthorized SIMs:
Contact your mobile provider immediately.
Visit a franchise with your CNIC and ask to block or remove unauthorized numbers.
Report identity misuse to PTA if needed.
Keep your CNIC information private and never share it with unauthorized vendors.
Privacy and Responsible Use
While checking SIM details can be helpful, it’s important to respect privacy and use the information responsibly. Avoid using any platform that shares complete personal data like home addresses or CNIC copies — that may violate privacy laws. Only use this information for personal safety, fraud prevention, or verification purposes. Misuse of someone’s private data can lead to serious legal consequences.
Real-Life Scenarios Where SIM Info Helps
Unknown caller:
You receive repeated calls from a number you don’t recognize. You use TrueCallID or a SIM info lookup tool and find that the name doesn’t match anyone you know. You can block the number or report it.
Unauthorized SIMs under your name:
When you check your CNIC, you find several numbers registered that you never used. You visit the network office to deactivate them and protect your identity.
Business verification:
If you run a small business and want to verify a customer’s number before proceeding with a delivery, you can check SIM info to confirm that the name matches.
Lost or stolen phone:
If your phone is stolen, check your CNIC records to ensure no new SIMs were registered under your name. Immediately contact your provider to block the number.
Limitations and Risks
Although SIM info checks are useful, there are some limitations and potential risks.
Data accuracy:
Not all lookup websites or databases are accurate. Some may display outdated information, especially if ownership of a number recently changed.
Privacy concerns:
Avoid using any website or app that shows complete personal data of others without consent. This is not only unethical but may also violate the law.
Fake or illegal websites:
Be cautious of platforms that claim to offer call records, addresses, or live tracking of SIM cards. These are often scams or illegal.
Over-reliance:
Checking SIM owner details helps, but it doesn’t guarantee safety. Scammers can use fake IDs or spoofed numbers. Always verify further if needed.
Legal compliance:
Make sure the service or app you use follows Pakistani law and PTA guidelines. Using unauthorized tools can get you into trouble.
