SMS Gateway turns the Android phones you already own into a private SMS platform. You install the gateway on a machine you control (a small server, a VPS, a computer in your office), you pair one or more phones with it by scanning a QR code, and from then on you send and receive SMS from a web dashboard or from your own software through an API. The messages leave from your SIM cards, at your operator's price, and nothing passes through a third-party platform.
You pay for the licence once, and you keep it.
What you can do with it
| You want to | What the gateway gives you |
|---|---|
| Send appointment reminders, delivery notices or one-time codes | An API: your application sends a request, a phone sends the SMS, you get the delivery status |
| Answer your customers by SMS as you would in a chat | A Conversations screen with one thread per contact, replies sent from the dashboard |
| Announce an offer, an opening or an event to a whole list | Campaigns sent in waves to a group of contacts, with progress, pause and cancel |
| Reply automatically outside business hours, or to a keyword | Rules that react to an incoming SMS: automatic reply, label, add to a group, call your URL |
| Personalise each message with the first name or the order number | Templates with variables, filled from your contacts or from the API call |
| Know whether a link in your SMS was opened | Short links hosted by your own gateway, with a click count: create them in the Short links screen, or turn on Shorten and track links when you send a message or a campaign |
| Feed your CRM or your own tools with every message received | Webhooks: the gateway calls your URL on each event (message received, delivered, failed) |
| Send more, or through the right operator | Several phones and SIM cards, a daily quota per SIM, and routing by number prefix |
Why it matters
Your data stays with you. Your messages, your contacts and your logs are stored on your machine and nowhere else. No SMS, no phone number and no contact ever reaches our servers: the only thing the gateway sends us is what the licence needs (a fingerprint of your key, the version, the machine fingerprint and the number of paired phones).
You own the licence. A single payment and a perpetual licence: no subscription to renew, no monthly bill, no price per message.
It keeps working when we are unreachable. If our licence server is down, or if your machine has no internet access for a while, your gateway keeps sending and receiving. An outage on our side is never treated as an invalid licence.
You keep control. You decide which phones send, at what pace, at what hours for campaigns, who has an account on the dashboard, which applications can use the API, and how often your data is backed up. You can export your data at any time and leave with it.
What you need
- A machine that stays on: a VPS, a small server, a mini-PC or a computer at the office, with Docker.
- One or more Android phones with a SIM card, kept on charge and connected to the network.
- Your licence key, shown in your customer area after purchase.

The dashboard is available in English, French, Spanish and Italian. This documentation is written in English and French, and the installation guide is also available in Spanish and Italian. A page that is not translated into your language is shown in English, with a notice saying so.
You can read this documentation in two places: on our website, before you buy or install, and inside your dashboard, under Documentation, once your gateway runs. Both show the same pages.
