You need to call O2 to enable the function, @Immy- numbers in this Guide: Coronavirus Community Help and Support, call around 8am or shortly thereafter. 0800 587 4005 seems the best one to call currently.
Other options are available that cost less: Guide: Conference Calling Hints and Tips - Avoiding Call Charges
Good luck!
