Handing a phone to a child, or worried about a lost handset being used to run up call charges — call barring on your Ooredoo Oman Hala line locks out specific call types at the network level, so the restriction can’t be undone just by restarting the phone or removing the SIM.
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# |
For a child’s phone
Barring all outgoing calls (*33*PIN#) while leaving incoming calls open means a child’s Hala line can still receive calls from parents but can’t dial out independently — useful for a first phone intended for emergencies and being reachable, not for making calls. Because the bar is set with a PIN only you know, it can’t be lifted by trial and error.
For a lost or misplaced phone
Barring all outgoing calls the moment you realise a phone is missing stops anyone who finds it from running up charges on your account, even before you’ve had a chance to formally report it lost or get a replacement SIM. It takes seconds via another phone if you can reach Ooredoo Oman support, and holds until you personally remove it.
Set your own PIN first
Every Ooredoo Oman line starts with the same factory PIN — 0000 — which means the bar only genuinely protects you once you’ve changed it. Call 1500 to set a personal PIN before you rely on barring for security rather than just convenience.
These codes are identical on Omantel, so nothing changes if you switch between Oman’s two networks. Need the opposite — redirecting calls rather than blocking them? See Ooredoo Oman call forwarding.
Codes are the GSM/3GPP standard supplementary-service set, verified against Ooredoo Oman’s official support guidance, July 2026.

Frequently Asked Questions
Does barring work on Hala prepaid?
Yes — call barring is a network feature, so it works on both Hala prepaid and Ooredoo Oman postpaid lines.
What is the default PIN?
0000 until you change it. Dial 1500 to set a personal PIN so the bars can't be lifted without your knowledge.
How do I remove all bars?
Enter #330*PIN# to cancel every bar in one step, then verify with *#33#.
Can I bar outgoing calls but still let someone receive calls?
Yes — *33*PIN# blocks only outgoing calls; incoming calls are unaffected unless you separately apply *35*PIN#.
Is barring reversible if I set it on a lost phone?
Yes — as soon as the phone is recovered, dial #330*PIN# from it (or contact Ooredoo Oman for help) to remove the bar.
