When did you last check how many SIM cards are registered under your Iqama? If the answer is “never,” you’re not alone — but it’s worth doing. Unauthorized numbers could be used for fraud, illegal activity, or running up bills in your name — and you would be the one held responsible.
Under Saudi telecom regulations, every SIM registered in the country must be tied to a valid ID — which means every unauthorized number linked to your Iqama is traceable back to you. Data-only SIMs are the exception to most limits, but for regular voice and prepaid lines, the thresholds are tighter than you’d think. Bottom line: if you don’t recognize a number, don’t ignore it.
Option 1: Full Check (Recommended)
This method gives you the most comprehensive information about your registered SIM cards. Before you start, have these ready: your Iqama number, date of birth, and access to one of your registered mobile numbers.
Follow these simple steps:
- Visit the official Mutasil Individuals portal (the CST’s SIM verification platform)
- Switch the language to English by selecting “ENGLISH“
- Enter your Iqama number in the “Person ID” field
- Add your date of birth in the “Birth Date” section
- When asked “Do you have mobile number?“, select “Yes” and enter one of your registered mobile numbers
- Click the “Inquire” button
- You’ll receive a verification code on the mobile number you provided – enter this code and click “Submit“

Once verified, you’ll see a detailed list showing all mobile numbers and data SIMs linked to your Iqama, including the complete phone numbers and their respective service providers. This gives you a clear picture of which numbers are registered with which telecom companies under your name.
Option 2: Basic Check (No Phone Needed)
If you don’t have access to any registered mobile numbers, you can still perform a basic check. While this method won’t show you the complete phone numbers, it will tell you how many SIMs are registered and with which networks.
Here’s how:
- Go to the same Mutasil Individuals portal
- Enter your Iqama number and date of birth
- Select “No” when asked about having a mobile number
- Click “Inquire“

You’ll get a summary showing the total number of mobile connections registered under your name with each network provider.
Option 3: Use the CST App
The same verification is available through the official CST mobile app (available for both Android and iOS) via the ‘Argami’ feature. Simply download the app, create an account and log in to your account to view your registered mobile numbers.
If you discover SIM cards registered under your Iqama that you never authorized, act quickly. Here’s what to do:
First, contact the relevant telecom provider directly:
- STC: Call 900 or visit a service center
- Mobily: Call 1100 or visit a branch
- Zain: Call 959 or visit a store
- Other providers: Check their official website for contact details
Have your Iqama number and the unauthorized phone numbers ready when you call. Request immediate cancellation of any unfamiliar SIM cards.
If the provider doesn’t resolve the issue or you want to escalate, file an official complaint directly with the CST through their official portal.
Once the numbers are removed, perform another check using one of the methods above to confirm the unauthorized SIMs are gone.
Make it a habit to check every few months. It takes less than two minutes and could save you from a serious headache down the line.
