Ericsson W21 - Manual (Page 17)

Configuration and Management
Normally, you have to enter the PIN to activate the Ericsson W21 data
services. In some cases however, authentication is not required and it is
possible to use the services without entering any PIN.
Type the PIN in the “PIN” field.
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.

the service provider’s network. It usually has the format
<name.service_provider.country>. Different APNs for the GSM (2G) and
UMTS (3G) networks may be required.
