6.3.3 Fixed Number Dialing
Fixed Number Dialing is supported when a SIM providing this service is
installed. When enabled, only calls to fixed numbers stored on the SIM are
allowed.
6.3.4 Emergency Calls
Emergency calls have its own dial plan and multiple numbers can be
configured.
It is possible to place an emergency call (e.g. 112, 911) without having to
enter a PIN code, when the PIN lock feature is enabled, without a SIM card
present in the unit, or if the device is locked to the network by a specific
MCC and/or MNC. This ensures emergency calls will always be established
regardless of the configuration of the Ericsson W35.
Emergency numbers are handled as follows:
• If a SIM card is present, emergency number from the dial plan are
used.
• If no SIM card is present in the unit, the numbers 112, 911, 000,
08, 110, 999, 118 and 119 are also handled as emergency
numbers and will be possible to dial.
6.4 Supplementary Services
The UMTS/GSM supplementary service codes (e.g. #67# etc) can be
configured with any service code in order to have the same service codes
as in a fixed network.
Supplementary services can only be used with a DTMF telephone
connected to the Ericsson W35.
The supplementary services described in the following subsections can
automatically be customized by setting a national profile. Profiles for the
following countries are currently supported: Austria, Australia, Spain,
Hungary, New Zealand, Sweden, United Kingdom and United States.

This service enables the caller to be notified of an incoming call during a
conversation. The subscriber can then answer, reject, or ignore the

The service can also be configured to accept a temporary deactivation by
dialing a prefix (e.g. *70) prior to or during a call. The Call Waiting service
will be reactivated when ending the call.
6.4.2 Call Management with R-codes
This service enables the caller to interrupt an active call (placing the caller
on hold), make a new call and then subsequently, switch between the old
and new call. It is also possible to release either of the calls, putting all
three in a conference call or “break up” a conference call into two separate
