Wait for an o2 employee and don't spread your concerns across the forum.

I am still waiting for O2 employee to respond !

May take a few days. Have to be patient.‍♂️

Hello @bharathkanak ,

we’ll be happy to help you with activating the conference function of your contract. For that we’ll need some additional information from you. You’ll be receiving a private message from our Supportaccount for further communication about this.

Kind regards, Sven
