A51 Call barring issue

[GinLondon]

Help please, my A51 opens countless pages and links while I am talking on the phone.  Either this or today's update has created an issue with call barring.  I cannot call out as calls are barred so I go to the phone call settings 'supplementary services' and call barring is not switched off.  Worse, I cannot do anything because it wants a 4 digit password that I don't have.  Is my only option to do a factory reset?

I'm wondering if the 4 digit password is the sim pin which is a security feature to stop a person inserting the sim into another phone.

Is that feature turned On ?

Before a factory reset first try clearing the system cache files via turning the phone Off and then from a set series of button presses go into the phones system files and clear the cache files. No info is lost this way.

A very last resort is to back up and remove any relevant Sd card and factory reset.

A Samsung Experience Store or Samsung Service Centre can help too.

I wish you all the best with this situation.

Thanks for the advice. 

I checked and the sim pin is not activated (clearly I was unaware of all the things a phone could have!) but while I was looking for this setting I noticed that my phone number comes up as unknown.  I wonder if this is the reason I cannot make phone calls.  I ejected and reinstalled the sim card and restarted the phone in hopes, but still I can not make phone calls.  

I've just tried putting the sim card in another phone and it is the same  issue, so maybe I need to contact my provider.

Turns out that the spending cap was at 0 and even though I was nowhere close to the limit the service provide started barring all my calls. It has been sorted out and wasn't the phone's issue at all.

iv got the same problem but I got a letter saying I had 7 days to pay my bill, I paid straight away but iv still got call barring so how do I rectify this problem please?.

Hi Karen,

The problem was actually that when I set up the phone I asked to have the amount I was allowed to go over my monthly limit set to £0. And it didn't kick in straight away but a month or two into the new contact I started getting the call barring. After beating my head against the wall between the carphone warehouse and O2, someone finally realised what the problem might be.  I raised the amount allowable to spend over the monthly allowance and the call barring went away. 

Strange but true.

Hope it helps
