How to Remove Call Barring on Samsung Galaxy S9 (O2 UK) If you’re trying to make a call on your Samsung Galaxy S9 and you hear a message saying “calls are barred” or “call barring is on,” you won’t be able to connect until the feature is turned off. Call Barring is a network-level feature (controlled by O2, not just your phone) that blocks certain types of outgoing or incoming calls. Here’s how to disable it on your S9, step by step. Before You Start
You need the barring password. O2 UK typically uses 0000 (four zeros) or 1111 as the default network password. If you’ve changed it and forgotten it, you’ll need to contact O2 customer service. Ensure you have network signal. This feature requires communication with O2’s servers.
Method 1: Remove Call Barring via Phone Settings (Recommended) This is the standard method for the Samsung Galaxy S9.
Open the Phone app (the green dialer). Tap the three dots in the top-right corner to open the menu. Select Settings . Tap Supplementary services (sometimes listed as “More settings” or “Additional settings”). Tap Call barring . You will see several options. To turn off all restrictions, tap All outgoing calls and All incoming calls (if they show as enabled). When prompted, enter the O2 barring password (try 0000 or 1111 ). Tap Turn off (or Disable ). samsung s9 remove call barring o2 uk
Repeat this for any other barring types you want to remove (e.g., International calls, Roaming calls). Method 2: Use O2’s Quick Network Codes (USSD Codes) If the settings menu isn’t working, you can use these special codes directly in the dialer.
Open the Phone dialer as if you’re making a call. Enter the relevant code:
| Action | Code to dial | | :--- | :--- | | Turn off All call barring | #002# | | Turn off barring for All outgoing calls | #33*0000# (or #33*1111# ) | | Turn off barring for All incoming calls | #35*0000# | How to Remove Call Barring on Samsung Galaxy
Press the call button . You don’t need to speak – the network will process the request. You should see a pop-up message: “Settings have been deactivated” or similar.
Method 3: Remove Call Barring via the O2 App or Website Sometimes the barring is active on O2’s side due to billing or account settings.
Open My O2 (app or website) and log in. Go to Usage or Manage your plan . Look for Manage extras or Call settings . Find Call Barring and toggle it off . You may need to confirm via SMS. Before You Start You need the barring password
What If It Still Doesn’t Work?
Try the other password – O2 sometimes uses 1111 for newer accounts. Check for “Fixed Dialling Numbers” (FDN) – On your S9, go to Phone > Settings > Supplementary services > Fixed Dialling Numbers. If enabled, this blocks all calls except a specific list. Turn it off (PIN2 is usually 0000 ). Check your bill – If you have an unpaid balance or a spending cap, O2 may automatically bar outgoing calls. Log into My O2 to check. Contact O2 UK – Call 202 from your mobile or 0344 809 0202. Explain that you want to remove all call barring and they can reset your barring password if needed.
