What is call waiting?
Let’s say you’re chatting on the phone to your mom and your best friend calls to tell you about a great hamburger they just ate. You don’t want to miss out on either, right? You might need to know where this hamburger could be found as well as how your aunt Mabel is doing. Never fear – call waiting is here!
Call waiting tells you there is a call coming in, while you’re already on another call.
