SMS

SMS on your own gateway, in the same queue as WhatsApp.

Use our gateway or connect the account you already have. Either way SMS sits in the same queues, the same consent ledger and the same reporting as WhatsApp and voice.

Where SMS still wins

WhatsApp is the better conversation. SMS is the better guarantee — it needs no app, no data connection and no opt-in to a platform.

Fallback
The WhatsApp template did not deliver, or the number has no WhatsApp. SMS goes automatically.
Authentication
One-time passcodes where the customer is mid-login and cannot switch apps.
Time-critical alerts
Outage notices, delivery windows and appointment reminders that must arrive regardless of data.
Cold outreach
First contact where you have consent for SMS but no WhatsApp opt-in yet.
Most common
Bring your own gateway
Connect the SMS account you already have and keep the rates you negotiated. We bill the platform, not your traffic.

Your rates, your carrier invoice

Simplest

One supplier, one invoice, one support contact. Sensible when SMS is a fallback channel rather than a core one.

What you get either way

The platform features do not change with whose gateway carries the message.

Same queues
Inbound SMS routes against the same skills and priorities as WhatsApp and voice.
One consent ledger
An opt-out on any channel stops SMS too, enforced at the moment of sending.
Automatic fallback
WhatsApp template first, SMS when it cannot be delivered — as one campaign, not two.
Two-way threads
Replies land on the same customer record beside the WhatsApp history.
Delivery reporting
Sends, deliveries and failures per country and per gateway, exportable.
Least-cost routing
Route by destination across multiple gateways where you hold more than one.

Sender IDs, short codes and content rules vary by country and are often subject to local registration. We confirm what applies in each of your markets during activation.

The SMS console

The console your team works in every day.

Segments, delivery, opt-outs and a replies queue — on your gateway or ours.

Outbound campaigns that end in a conversation, not a delivery report. Replies and call-backs land in a real queue, and opt-outs propagate across every channel.

Beside your other channels

SMS is one of four channels sharing the same queue and customer record.

Most businesses buy these four from four vendors. Here they share one queue, one customer record and one bill.

All four land here: one queueone customer recordone set of reportsone bill
The people behind it

Software runs the channels. People run the operation.

Every deployment is led by named people on our side and yours — not a ticket queue.
