The Service Provider-provisioned SIM card installs in a connector on the GPRS modem option board.
Along with each SIM card, the service provider supplies its provisioned:
-
SIM ID — a 19-digit number unique to this one card.
-
Provider APN — Access Point Name for the cellular provider network. The APN specifies the gateway between the provider’s mobile network and the Internet.
-
APN credentials - Username and password for authentication to the APN.
Be sure to get the username and password from the service provider (Wyless, for example). This is required for the GPRS modem
to make the PPP connection.
-
Phone number - Associated phone number (seen in any SMS messages sent by a hosted station).
-
Private IP address — Static IPv4 address within a private address space of the VPN wireless network.
True if a Wyless SIM, other service providers may or may not supply a fixed IP address.
-
IMSI — (International Mobile Subscriber Identity) a unique 15-digit GSM mobile device identity.
You use the supplied APN name and credentials in the platform configuration of the GPRS modem option (its SIM ID is automatically recognized). See Required platform GPRS setup.
In the case of Wyless as service provider, its associated private IP address is how you can connect to the JACE over the Internet using the service provider’s VPN (Virtual Private Network). See the first appendix section GPRS connectivity overview.
