2: The SIM Card and Your Account
• Inserting a SIM card
into your AirCard
• Removing a SIM card
You require a GSM/GPRS account and a SIM (Subscriber
Identity Module) card to use the AirCard. The SIM card is a
small chip (about the size of a postage stamp) that you insert
into the AirCard. The SIM contains account information used
by the network to validate your access.
Note: Without a valid SIM card
and a valid account, your
AirCard will not work.
Depending on how you purchased your AirCard, you may
already have an account. In this case, the SIM should be
included in your package. Otherwise, your retailer should
direct you to a local company that provides GSM service.
To activate an account, the service provider needs from you:
• Billing information (such as a credit card number) used to
collect payment for your network usage
• Possibly the IMEI (International Mobile Equipment
Identity)—a number that identifies your device (AirCard
model) on the GSM network. This number is printed on
the AirCard box and on the AirCard label.
Note: Keep a written record, in a
secure place, of the account
information that your service
provider gives you. Instructions
on creating a profile are in the
section ‘Configuring Your
Account” on page 33.
Your AirCard must be configured to use your account. If
purchased from a service provider, your AirCard may have
been pre-configured. Otherwise, you must obtain the
necessary information and set up a profile in Watcher.
Depending on your service provider and account, some or all
of this information must be entered in your profile:
• Phone number
• APN
1
• User name and password
Less commonly you may need to specify:
• An IP (Internet Protocol) address for your AirCard
• A DNS
2
address or addresses
• That IP header compression is to be used
1. APN (Access Point Name)—Name of the gateway between the
wireless network and other networks such as the Internet or a
corporate network (Example: internet.serviceprovider.ca).
2. DNS (Domain Name Server)—a computer that converts web
site names, such as www.sierrawireless.com, into IP
addresses, such as 64.114.87.11.
