Manually declining unwanted calls works, but it has a limit: your phone still rings, still shows a missed call, and the caller can simply try again — and again. Call barring on your Omantel line stops the call from connecting at all, at the network level, before it ever reaches your phone.
Quick answer
Standard GSM barring codes with your barring PIN (default 0000):
| Bar | Code |
|---|---|
| All outgoing calls | *33*PIN# |
| Outgoing international only | *331*PIN# |
| All incoming calls | *35*PIN# |
| Remove all bars | #330*PIN# |
Why this beats declining calls manually
Rejecting a call by hand still interrupts you every time, still logs as a missed call, and does nothing to stop the same number calling back in five minutes. A network-level bar via *35*PIN# (all incoming) means the calls simply don’t connect — no ring, no notification, no repeated interruptions to manage one by one. It’s the difference between fighting the same battle every time versus setting the rule once.
Common uses
- Before travelling: bar international outgoing (*331*PIN#) so a misdial or accidental call abroad doesn’t rack up charges.
- A device you’re not using yourself: bar all outgoing on a spare SIM or a phone lent to someone else, capping what it can be used for.
- Genuinely disconnecting temporarily: bar all incoming and outgoing together when you need a phone number to go fully quiet without deactivating the line entirely.
Set your own PIN
Out of the box the PIN is 0000 on every Omantel line — change it via 1234 so the bars stay under your control rather than being liftable by anyone who knows the factory default. Since these are GSM-standard codes, they match those on Ooredoo Oman exactly.

Frequently Asked Questions
Can I block only international calls?
Yes. Use *331*PIN# to bar outgoing international calls while leaving local calls working normally.
What's the barring PIN?
The default is 0000. Call Omantel on 1234 to set your own so nobody else can clear the bars.
How do I turn barring off?
Dial #330*PIN# to lift all bars at once, then confirm the status with *#33#.
Does barring stop the caller from even trying?
No — they can still dial, but the call won't connect to you; it typically reaches a network message rather than ringing your phone.
Is barring different from blocking a contact on my phone?
Yes — phone-based contact blocking only works on that specific device and can be undone by anyone with access to it. Network barring applies to the SIM itself and requires your PIN to remove.
