SIM Card
When you subscribe to a mobile network, you are issued a Subscriber Identity Module (SIM) card.
Your SIM card contains your personal subscriber data. To connect to a mobile network you must
first insert your SIM card that includes the appropriate network subscription into your PC300.
The SIM card is inserted into a slot in the lower face of the PC300:
Note:
The application software must be installed before you insert your PC Card into your PC or Mac.
Network and subscription requirements
The network subscription you use in conjunction with your PC300 depends on the functions and
features that are available from your network operator. Contact your network operator or service
provider to make sure the options that you require are available (UMTS/HSPDA, GPRS/EDGE and
SMS).
Note:
Network operators often provide a number of connectivity options such as WAP and
Internet. These are accessed via different APNs (Access Point Names). Verify the services
that you require, such as Internet, e-mail or corporate VPN (Virtual Private Network) service
are available through your Service operator and enabled on your subscription.
