To check how many SIM cards are registered on your iqama, use the free “Inquire about my numbers” service (Arqami) from CST, the telecom regulator that was called CITC until 2023. Enter your iqama number and date of birth on the Mutasil portal, and it shows the active mobile numbers and data SIMs registered to your ID with every network. The screenshots below show the service, with personal details blurred.
CITC SIM Check Online: Step by Step
- Open the Inquire about my numbers page on Mutasil (or the CST app). No login is needed.
- Enter your iqama number in Person ID and your date of birth.
- Answer “Do you have a mobile number?”. Choose Yes and enter one of your numbers, or choose No if you do not have a Saudi number yet. Follow any verification step on screen.
- Type the captcha code and select Inquire.
What the result shows
The result screen shows the total numbers registered with your ID number and the total service providers those numbers are with. A note at the top tells you to contact the provider about any number listed, for questions, complaints or cancellation.
If you sign in to the Mutasil platform, you can see your registered numbers without filling in the form. Business owners can run the same check with a Commercial Registration (CR) number.
The service lists only numbers that are active and authenticated (CST). A number that is active but not yet authenticated with your fingerprint must be sorted out with the operator, or it may be cancelled.

Other Ways to Check
- CST app: the same “Inquire about my numbers” service is available in the CST mobile app.
- Absher: there is no SIM check in Absher. Guides that describe an Absher “telecom services” route are out of date.
- Zain customers can also send a blank SMS to 700123 to check the ID registered to their line (Zain). Similar SMS codes that CITC listed for other operators in 2016 may no longer work.
How Many SIMs Are Allowed on an Iqama?
Expats can register a maximum of 2 prepaid SIM cards, counting voice and data SIMs together, across all networks. Saudi citizens can register up to 10. These limits come from a 2017 CITC decision, and CST has not published a newer figure. See our full guide to the SIM card limit in Saudi Arabia, including postpaid lines and number porting.
Found a SIM You Do Not Recognise?
CITC has made clear that the person a number is registered to is responsible for any misuse of it (CITC, 2016). If the check shows a number you do not use:
- Contact the operator and ask them to cancel the line.
- If the operator has not solved it within five working days, escalate the complaint to CST through the Mutasil portal (“Escalate telecom complaints”).
- You can also call CST on 19966.
- Run the check again to confirm the number has been removed.

| Operator | Customer care |
|---|---|
| STC | 900 |

Never let anyone register a SIM with your iqama, and do not sell or lend a SIM that is in your name.
