To Initiate Call Waiting:
When you're on the line and a second call
comes in, you'll hear a tone to let you know
you have another call. When that happens,
you have three choices:
1) 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.
2) Or, end the first call by asking the
first caller to hang up. This automatically
connects you to your waiting call.
3) Or, ignore the Call Waiting tone. After
30 seconds, the waiting caller will hear a
message indicating that you're not
available, or will be forwarded to your
voice mailbox if you subscribe to a
messaging service.
To Cancel Call Waiting:
Before a call, dial *70 + the 10 digit
number you are calling + SEND.
