2.3.1 Internet Access
The first part of the Configuration Wizard includes Internet authentication.
Depending on the current Internet service setup, the requests on
authentication may differ. The service provider provides the required
authentication details.
Note: Only enter details that you have received from your service
provider and leave other fields empty.
SIM Authentication
The service provider provides you with a SIM card. This SIM card contains
information about the subscription and is normally protected by a PIN
(Personal Identification Number) and a PUK (Personal Unblock Key) code.
Note: Emergency calls (i.e. 112 or 911) can always be made, even
without a SIM card or the correct PIN code.
Normally, you have to enter the PIN to activate the Ericsson W20/21 data
services. In some cases however, authentication is not required and it is
possible to use the services without entering any PIN.
You can enter the PIN via the Ericsson W20/21 internal web pages.

Configuration and Management
1/1551-CRH 102 167 Uen Rev C 2007-04-19 13
To enter the PIN via the Configuration Wizard, type the PIN in the PIN field
on the Internet Access: SIM Authentication page, see Figure 6.
Thereafter, you can select the Remember my PIN check box. This makes
SIM authentication automatic and you will not have to enter the PIN in case
of a system restart. Click Next to proceed.
Unblock SIM card
If three attempts have been made with an incorrect PIN, the SIM card is
blocked. The PUK is required to unblock the card. Click Unblock SIM .
The Unblock SIM page is displayed:
