How does FirstNet keep SMS sign-in working for Microsoft Entra ID?

Entra SMS sign-in · Answered by FirstNet Technology Services

Short answer

FirstNet is a telephony provider in the Microsoft Security Store. Your admin selects FirstNet there, then runs our setup in your Azure subscription, and your sign-in codes are delivered over South African SMS routes.

In detail: FirstNet SMS Delivery for Entra ID Sign-in

How it works:

  • Entra ID creates the code and Microsoft's connector in your Azure subscription passes it to FirstNet, which sends it on local routes
  • Country allow-lists and velocity limits help stop SMS pumping fraud, and monthly budgets alert at 80% and 100%
  • Your own portal shows every send, its delivery status and your spend
  • FirstNet only delivers the code: Entra ID creates and checks it

The steps are scope, connect, approve, pilot and roll out. You need Entra ID P1 or P2, an Azure subscription your admin owns, and a Global Administrator. Contact us to book a 30-minute Entra SMS readiness check.
