NAC overview
The Network Access Control feature, otherwise known as the NAC, analyses and directs inbound network subscribers to a captive portal where they can:
-
opt-in for data roaming
-
view and purchase data plans and offers
-
view and manage their current data plans
Managing a data plan consists of the ability to pause or terminate the plan as well as cancel or (de)activate a plan.
Basic NAC flow
When a subscriber arrives into your network as a silent roamer, they receive a welcome SMS that invites them to roam on your network. The welcome SMS contains a URL which directs the subscriber to the Captive Portal component of the NAC. It is within this Captive Portal that subscribers can opt-in, purchase plans, and manage their data plans.
| If a roaming subscriber attempts to browse without an active plan, they’ll simply be redirected to the Captive Portal. See the Get to know the Captive Portal for more in-depth information regarding the Captive Portal. |
