The SMS module is the phone-number counterpart to Self-Provisioning by Email. The guest enters a phone number, receives a verification code by SMS, and enters the code to gain access. Typical audiences: venues where guests are mobile-first, retail and hospitality, events where email is impractical, venues serving guests who don’t carry laptops.

How a guest signs in

  1. On the Captive Portal, the guest picks SMS and enters their mobile phone number.
  2. An SMS arrives with a one-time PIN code.
  3. The guest enters the PIN on the portal. If the PIN matches, access is granted.

Prerequisites

SMS delivery requires an SMS gateway to be configured on this Sign-In Context. The SMS provider is configured per Context — different Contexts can use different providers if needed. Without a configured provider, the module can be activated but no codes will be delivered. Supported gateway shapes depend on your plan. Coordinate with your Netgraph point of contact to provision an SMS gateway for the Context.

​
Activate the module

1

Open the module

Go to Sign In Modules → SMS Login.
2

Configure the SMS provider

On the Configuration tab’s SMS Provider sub-tab, connect the SMS gateway this Context should use.
3

Set the default country code and session length

On the Basic Settings sub-tab, pick the default country code shown on the portal and the session length granted by a successful sign-in.
4

Activate

Click Activate SMS Guests Login Module.
5

Test

Send a test code to your own phone before enabling for guests.

​
Configuration

The module Configuration tab has three sub-tabs:
  • Basic Settings — default country code pre-selected on the portal, session length granted by a successful sign-in, and the post-sign-in redirect URL.
  • SMS Provider — connection to the SMS gateway provisioned for this Context.
  • Language Settings — per-language overrides for the Captive Portal strings.

​
Managing guests

The main tab lists registered SMS guests by phone number, with last login, total logins, and device counts.
  • Filter by phone number.
  • Revoke a guest — deletes the record; next sign-in requires a fresh verification.

​
Access Policies

SMS is not gated by an Access Policy — if the module is active at Context level, it is available to any guest who reaches the Captive Portal. Session length and redirect behaviour are configured on the module’s Basic Settings sub-tab, not on a policy.

​
SMS delivery costs

SMS delivery has a direct per-message cost that flows through your SMS provider. If your provider doesn’t already rate-limit traffic, coordinate with them on how to handle repeated requests for the same number.

Self-Provisioning by Email

Same self-service pattern, verified by email instead of SMS.

Meeting Host

Host-approved flow where an employee vouches for the guest.
