How To Enable/Disable Call Waiting

How to Switch between two phone calls:

When you're on call and a second call comes in, you'll hear a tone to let you know that you have another call. When that happens, you can put the first call on hold by pressing "Send." You'll automatically be connected with the second call. To return to the first call, press "Send" again. To switch between the two calls, press "Send." Or, you can end the first call by asking the first caller to hang up. This automatically connects you to your waiting call.

How to Cancel Call Waiting:

To cancel Call Waiting: Before a call, dial *70 + the 10-digit number you are calling + "Send."
