5.4.2 Configuring Cell-Sentry Budget Control
Cell-Sentry enables you to monitor and/or limit the amount of usage on the Cellular WAN
interface. This feature enables you to utilize a carrier's lower cost data service plans and
ensures that you do not exceed your plan allowance.
" Actual usage statistics on the carrier's 3G network may differ from the LAN-
Cell's counters. Set your budget limits lower than the maximum allowed on
your plan.
