Wi-Fi calling

[ICK]

It says I need to contact o2 to enable Wi-Fi calling 

[Bambino · Accepted solution]

@ICK Yes you need to speak to customer service.
Call 202 from your mobile or 0344 809 0202 or 0800 032 1402 from any phone or numbers here: Guide: Coronavirus Community Help and Support 
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 (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)
Or you can call them on 0800 081 0255

Yes, you need o2 to turn it on first, then you enable it on your account and finally turn it on in your phone @ICK . All that if you are a pay monthly customer - WiFi calling is not on PAYG.

You can either call 202 from your phone, or  0344 809 0202 from any phone, or contact them on social media:
