Sim unbar

[AOlu]

Hi,

I am away from the country and would like to know how to unbar my sim. I tried on the app, is requesting a verification code however I cannot receive the texts. 
I cannot contact O2 via calls as they too aren’t connecting. Is there an email I can use to get this verification sorted?

Thanks in advance

@AOlu You can download Skype Guide: A Guide to Skype and call customer service for free on +44800 032 1402 or +44800 902 0217 (Payment Management)
When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say 'Upgrade', 'Lost/Stolen', or 'Fraud' if the suggestion above doesn't get you through.
Best time to call is 8 am.
You can also reach O2 via social media:
Facebook (https://o2uk.co/O2CFB), Twitter (now X) (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)
