SPI, SPNI, WASI
The SPI, SPNI, WASI field displays the current settings for the various network identifiers, sepa-
rated by slashes. The first number shown is the Service Provider Identifier, or SPI. This number is
a globally used identifier for the network provider the modem is currently using. The middle num-
ber is the Service Provider Network Identifier, or SPNI, which identifies the specific network region
or domain you are currently in. The final number is the Wide Area Service Identifier, or WASI. The
WASI represents a group of network providers that have agreed to provide service over a large
geographic area.
To change any of these identifiers, tap the text field to open the Service Group Entry window.
You can directly edit any of these values as you would normal text.
Service ID Pref
Some network providers have set up roaming agreements, similar to that used by cellular phones,
to expand their coverage areas. Therefore, you can use a different network provider than the one
you have an account with if there is a roaming agreement in place. The Service ID Pref field con-
trols how the modem uses your chosen network provider and other providers. If it is set to Only
SvcID, the modem will only use the network provider entered during the initial configuration done
using the Setup Wizard utility. PreferSvcID indicates that the modem will first try to register with
your chosen network provider, but if it cannot, it will attempt to use another provider. Selecting
IgnoreSvcID or Any SvcID tells the modem to use the first available network provider it finds.
