18 During a Call
To use telephone banking services or to control an answering machine, you
need to use codes. These codes are sent as tone signals (also known as DTMF
tones or touch tones).
• Press the appropriate keys (0-9, * and #).
Tip! You can also save a code together with a phone number in the Phone
Book. See “Your Personal Phone Book” on page 23.
During a call, the display shows the duration in minutes and seconds. If you
prefer, you can have the call cost displayed, provided your network and your
SIM card support this feature. See “Knowing the Call Time/Call Cost” on
page 67 on how to use this feature.
Your phone is capable of handling more than one call simultaneously. You can
put the current call on hold, and then make or answer a second call. You can
also set up a conference call with up to five people. See “Handling More than
One Call Simultaneously” on page 57 on how to use this feature.
