Making Calls
Before you can make and receive calls, you need to turn on the phone
and be within range of a network.
• Press and hold the NO key until you hear a tone.
The PIN
Most SIM cards are protected with a PIN (Personal Identity Number),
which you get from your network operator and which you need in
order to access the network. If
PIN: appears in the display after you
have turned on the phone:
1. Enter your PIN. If you make a mistake while entering your PIN,
delete the wrong number by pressing
.
2. Press Y ES .
If your PIN is entered incorrectly three times in a row, the SIM card
is blocked. If this happens, you can unblock it by using your PUK
(Personal Unblocking Key), which you also get from your network
operator. See “Locking the SIM Card” on page 106.
If Phone locked appears in the display, enter your phone lock code.
See “Locking the Phone” on page 107.
Network Search
After you have turned on the phone (and entered your PIN), the
phone searches for a network. When a network is found, the phone
beeps three times. The indicator light on top of the phone flashes
green and your network operator’s name (in most cases abbreviated)
appears in the display. This is called standby mode. You can now
make and receive calls.
Note:
If you do not reach standby mode, see “Error Messages” on
page 124 or “Searching for Networks” on page 103.
1. Enter the area code and phone number (note that some countries
may not use area codes).
You can edit the number before calling by pressing
.
2. Press Y ES .
3. Press NO to end the call.
