3-Way Calling (Multi-Party Calling)
The 3-Way or Multi-Party feature allows you to answer a series of
incoming calls and place them on hold.
If this service is supported by the network, and the SIM has the
feature enabled, all calls can be joined together. You are notified of
an incoming call by a call waiting tone. To activate the call waiting
feature, see “Call Waiting” on page 37.
1. Make a call by either dialing a new number and pressing
or receiving an incoming call and press (Accept).
2. Make a new call by pressing (Options) ➔ New Call,
then enter the new number and press (Call). Wait for the
new caller to answer. The first call is automatically put on hold.
3. Press ➔ ➔ OK to join with both of your callers,
the active call and the call on hold, in a single multi-party call.
4. Press to end the 3-way call.
