User settings
Your phone can be operated in 
TDMA networks as well as in 
GSM networks. You can set one of 
these operational modes as 
standard or switch between the two 
modes automatically. 

When turning on the phone for 
the first time, automatic selection 
is active.
• Automatic selection
When automatic selection is active, 
the most recently used network is 
searched and the phone determines 
whether a SIM card is inserted. 

Depending on the status, the 
currently available network is 
displayed for selection.
• GSM Only
Only GSM networks will be used 
when a SIM card is inserted. 
• TDMA  Only
Only TDMA networks will be used 
when a SIM card is inserted.

Locking restricts the use of your SIM 
card (not supported by all service 
providers). You need a 4-digit 
password that your service provider 
supplies you. You may need to be 
registered separately for each lock.

Outgoing calls
All outgoing calls (except 911 and 
112 emergency numbers) are 
barred.

Outgoing international
Only domestic calls can be made.

Outgoing international except 
home country
International calls are not permitted. 
However, you can make calls to your 
home country when abroad.

All incoming calls
The phone is barred for all incoming 
calls. (Forwarding all calls to the 
mailbox has a similar effect.)

When roaming
You do not receive calls when you 
are outside your home network. This 
means that no charges are incurred 
for incoming calls when roaming.

Status check
Displays information on your 
phone’s lock status: lock is set, lock 
is not set or status is unknown (for 
example, with a new SIM card).

Clear all
All locks are cleared.
