rushi bandre , via OnePlus Nord , Jun 19, 2021 : Hello, On my OnePlus Nord and OnePlus 5 call waiting is not working for Vodafone sim Card. If i am on call and other person tries to contact me I didn't get any notification. I also tried by changing sim into another phone and it works fine. But not working with any OnePlus device. I also went to the Vodafone Gallery they said call Waiting service is ON. But still i am getting this problem.
