No Caller ID

Hi @Mansoor Khan Khalil, 

thanks for your information under @o2_Support. 

As you told me that you would like to activate the Caller ID for your landline-number, please follow the following instructions: 

• Please go to www.o2online.de
• Then go to “Mein o2”and log-in
• then go to: Tarif & Optionen / Vertrag verwalten / Festnetzeinstellungen
• at “Festnetzeinstellungen” click the button “Weiter”
• you will then come to the point “Temporäre Rufnummernunterdrückung”: please click on the word “hier”
• you will then come to the point “Rufnummernübermittlung”: there you click on the point “Rufnummernübermittlung aktivieren” (activate Caller-ID)

I hope that you manage to activate the Caller-ID with this instruction. 

If you need any further support, just let me know. 

Loving greetings,

Tobias
