Saudi Arabia’s SIM activation runs on fingerprint verification specifically, not just a document scan — which is why activation across STC, Mobily, and Zain is described as instant once you leave the store: the biometric check is the actual registration event.
Quick answer
Insert the SIM, restart your phone. Activation is automatic once fingerprint verification clears at the store — no separate step needed.
Per-operator verification
| Operator | Verify with | Care number |
|---|---|---|
| STC | *166# or MySTC app | 900 |
| Mobily | *1100# or Mobily app | 1100 |
| Zain | *142# or Zain app | 959 |
If you left the store with a working SIM
It should already work by the time you get home — fingerprint verification is processed at the counter itself, unlike systems that verify against a database after you’ve left.
Common reasons for delay
- Fingerprint verification still processing (rare, but possible)
- Network coverage issue — try another location
- Phone not restarted after SIM insertion
Once active, check your balance via the relevant operator guide linked above.
