Why You Should Regularly Check SIMs Registered on Your CNIC
Staying vigilant about the SIM cards linked to your CNIC isn’t just a good practice—it’s a necessity in Pakistan’s evolving telecom landscape. The Pakistan Telecommunication Authority (PTA) mandates that all SIMs be registered against a valid CNIC to curb misuse, but fraudsters still find ways around it. According to recent reports, over 10,000 cases of SIM-related fraud were reported in Pakistan in 2024 alone, highlighting the urgency.
The Importance of SIM Registration in Pakistan
SIM registration began in earnest in 2009 when PTA launched the SIM Information System to combat terrorism and illegal activities fueled by anonymous mobile connections. Today, every Pakistani citizen can have up to 5 SIMs registered per CNIC across networks like Jazz, Zong, Telenor, Ufone, and SCO. This limit prevents overuse and ensures accountability. By checking your SIMs, you comply with PTA regulations and avoid penalties, such as SIM blocking during periodic verifications.
Risks of Unauthorized SIMs and Identity Theft
Unauthorized SIMs on your CNIC can lead to severe consequences. Scammers might use them for phishing, blackmail, or even financial fraud, leaving you liable. For instance, in a 2023 case study from Lahore, a victim discovered 3 extra SIMs registered fraudulently, which were used in a banking scam totaling PKR 500,000. Regular checks help you spot these early. Other risks include privacy breaches, where your personal data is exploited, or legal issues if the SIM is linked to criminal activities.
Statistics on SIM Fraud in Pakistan
To put it in perspective, here’s a table summarizing key stats from PTA and FIA reports (2023-2025):
| Year | Reported SIM Fraud Cases | Blocked Unauthorized SIMs | Common Networks Affected |
| 2023 | 8,500 | 45,000 | Jazz (35%), Zong (25%) |
| 2024 | 10,200 | 52,000 | Telenor (30%), Ufone (20%) |
| 2025 (Q1) | 2,800 | 15,000 | All networks evenly |
These numbers show a 20% year-on-year increase in fraud, driven by digital scams. By learning how to check SIM on CNIC by SMS, you can join the millions who proactively secure their identities.
Step-by-Step Guide: How to Check SIM on CNIC by SMS
The simplest and most accessible way to check SIMs registered on your CNIC is via SMS. This method works on any mobile phone, doesn’t require internet, and provides instant results. It’s optimized for PTA’s system and costs just PKR 2 + tax per query.
Preparing Your Phone and CNIC
Before starting, ensure you have:
- A working mobile SIM (any network).
- Your 13-digit CNIC number (without hyphens, e.g., 1234567890123).
- Balance for the SMS fee.
This method is PTA-approved and has been in use since 2010, helping over 100 million users verify their details.
Detailed Steps to Send the SMS
- Open your phone’s messaging app.
- Create a new message.
- Type your CNIC number in the message body (no spaces or dashes).
- Send it to the short code 668.
- Wait for the reply SMS, which arrives within seconds.
The response will list the total active SIMs per operator. For example: “Jazz: 2, Zong: 1, Telenor: 0, Ufone: 1, SCO: 0. Total: 4.”
If you get no response, check your balance or try again after 5 minutes—network glitches are rare but possible.
Understanding the SMS Response
The PTA reply breaks down SIMs by network, showing only active ones. If the total exceeds 5, it’s a red flag for fraud. Note: This doesn’t list phone numbers, just counts. For full details, use the online method (covered below).
Troubleshooting Common SMS Issues
- No Reply: Ensure correct CNIC format; resend or check signal.
- Error Message: If it says “Invalid CNIC,” verify your ID at a NADRA center.
- High Costs: Limit queries to once a month to avoid fees.
This SMS method is ideal for quick checks and answers the popular query “how to check number of SIMs on CNIC without internet.”

Network-Specific Checks for Detailed Verification
Each telecom provider offers USSD codes or apps for checking SIMs on your CNIC. Here’s a comparison table:
