In today’s digital world, communication is almost impossible without SIM cards. Whether it’s making calls, sending text messages, or browsing the internet, SIM cards connect us to the network. However, with the growing cases of fraud, identity theft, and scams, it’s no longer enough to just use your SIM card—you must also keep track of how many SIMs are registered on your ID card.
Unfortunately, many people don’t realize that multiple SIMs may be linked to their ID card without their knowledge. Some may forget about an old SIM they purchased years ago, while in other cases, fraudsters misuse stolen ID information to register SIMs under someone else’s name. This can put you at risk of legal trouble, scams, or even cybercrimes.

By the end of this article, you’ll know exactly How to check SIMs on ID card and why making it a regular habit is one of the smartest things you can do in today’s digital age.
Why It’s Important to Check SIMs on Your ID Card
The most important reason is security. If someone registers a SIM card under your ID without your knowledge, you might be held responsible for activities you never did. Imagine if a scammer used such a SIM to commit fraud or make threatening calls—you could be dragged into investigations unnecessarily.
Other key reasons include:
- Legal protection – Avoid being linked to SIMs involved in illegal activities.
- SIM management – Stay aware of how many active SIMs you own.
- Avoiding registration limits – If you’re already at the maximum limit, you won’t be able to purchase new SIMs until you block unused ones.
- Peace of mind – Confirms that nobody else is misusing your CNIC.
Checking your registered SIMs is like checking your credit report—you may not do it daily, but regular monitoring protects you from hidden risks.
Legal SIM Registration Limits: Rules You Must Know
Every country’s telecom authority has rules regarding the number of SIMs one person can own. In most cases (such as Pakistan’s PTA regulations), the limit is five SIMs per individual.
These can be from a single network or spread across multiple mobile operators. Once you reach this limit, you cannot register a new SIM until you deactivate an existing one.
This rule was introduced to:
- Prevent illegal SIM sales
- Reduce misuse of identity cards
- Strengthen security against fraud and terrorism
- Ensure fair use of telecom services
Pro Tip: If you’re planning to buy a new SIM but already have five active ones, check your registered numbers first. Block the ones you no longer use so your ID card stays clean.
Methods to Check SIMs on ID Card (Step by Step)
Here are the most effective methods you can use to check how many SIMs are linked to your CNIC/ID card.
1. Checking via SMS Service
This is the quickest and simplest way.
- Open your SMS app.
- Type your CNIC number (without dashes or spaces).
- Send it to 668 (official PTA code in Pakistan).
- Within seconds, you’ll receive an SMS showing:
- Total number of active SIMs
- Names of mobile networks

Advantages:

Some telecom operators allow you to check SIM registration using short mobile codes.

This is especially useful if you don’t remember whether a SIM is active or if you’re using multiple operators.
3. Checking via Mobile Apps
For smartphone users, mobile apps are another convenient option. Each telecom company has an official app (e.g., Jazz World, My Zong App, Telenor App, Ufone App).

- Navigate to the SIM management section.
- View all SIMs linked to your ID.
Advantages:
- Easy to manage SIMs.
- Option to block numbers online.
- Access to billing and usage details.
4. Checking via Customer Service Centers
If you want a more reliable and official method, visit the nearest customer service center or franchise of your mobile network.
- Take your original CNIC with you.
- Request SIM verification.
- Staff will provide a complete list of SIMs under your ID.
- If you find unknown SIMs, you can block them immediately.
Advantages:

Common Problems and Their Solutions
Sometimes, people face issues while checking SIMs. Here are some common problems and how to solve them:
- Incorrect CNIC Entry – Always type your CNIC correctly without dashes or spaces.
- Network Delays – If you don’t get a reply, wait a few minutes and try again.
- Unregistered SIMs – If your SIM isn’t linked properly, visit the nearest service center to fix it.
- Reached SIM Limit – Block unused SIMs before trying to register a new one.
Why You Should Block Unused SIMs
Unused SIMs are like open doors—anyone can walk in and misuse them. If you no longer use a SIM, block it immediately.
Reasons to block unused SIMs:
- Prevent fraud or criminal misuse.
- Keep your CNIC record clean.
- Free up space for new SIM registrations.
Blocking a SIM is simple and can be done via app, SMS, or customer service center.
Tips for Safe SIM Usage
Along with regular checks, follow these best practices:
- Never share CNIC copies with unknown people.
- Buy SIMs only from official franchises.
- Regularly verify SIM ownership every few months.
- Immediately report suspicious SIMs to your provider.
- Don’t keep unused SIMs active—block them to stay safe.
Role of Biometric Verification
To reduce fraud, most telecom authorities now require biometric verification when buying a new SIM. Your fingerprint is scanned and matched with your CNIC details.
While this has greatly improved security, mistakes can still happen. That’s why regular monitoring of registered SIMs is still important.
Why Awareness Matters
A big challenge is the lack of awareness, especially in rural areas. Many people casually hand over copies of their ID cards without realizing the risks. Some even allow others to use their CNIC to buy SIMs.
Awareness campaigns in schools, colleges, and community centers can help spread the message: Protect your CNIC. Verify your SIMs. Stay safe.
Why You Should Check Regularly
Checking once isn’t enough. Fraud can happen at any time. Make it a habit to check every few months.
This way, you’ll always stay updated on:
- Any unauthorized SIMs under your name.
- Whether you’ve reached your SIM limit.
- Which SIMs you can safely block.
Regular monitoring = ongoing protection.
