Sending a free SMS to a French mobile from a browser answers a simple need: getting a short message across, right away, without installing an app or opening an account. With **Envoyer SMS Gratuit**, the send happens without sign-up, without advertising, and without limits. One legitimate question remains: which data actually comes into play when you click "Send"?

## What a free send needs

To deliver a message, only one thing is essential: the **recipient's mobile number**, in the French format starting with `06` or `07`. Add to that the text itself, limited to **160 characters** per SMS (beyond that, the message is split into several segments). No name, no email address, no password is requested: the service does not create an account and therefore has nothing to remember about you.

## No sign-up, no needless collection

The absence of a sign-up is not just a convenience: it's also a way to keep data to the strict minimum. **Envoyer SMS Gratuit** builds no advertising profile, displays no banner, and resells nothing. In accordance with the **GDPR**, the information processed is limited to what enables delivery of the message, and nothing more.

## The anti-abuse technical logs

A free, open service remains responsible for what passes through it. To prevent spam and malicious uses, sends are **logged technically (IP address, timestamp)** for a limited period. These logs are not used to track you: they make it possible to block abuse and may be handed **to the authorities upon judicial request**. [Harassment, impersonation, and threats](/guides/send-an-sms-without-giving-your-number) are prohibited and perfectly traceable. A free send is a right to simplicity, not a licence to cause harm.

## Don't trust a secret to an SMS

The SMS, free or paid, is not end-to-end encrypted. Avoid writing passwords, banking details, or sensitive data in it. Be wary too of messages that ask you for such things: learn to spot [SMS phishing](/glossaire/smishing) and [bank fraud](/arnaques-sms/bank-fraud).

## Where the data is hosted

Transparency is part of the service. The infrastructure of **Envoyer SMS Gratuit** is operated by **DIM SOLUTION** and runs on **Hetzner** servers located in Europe. Processing therefore stays within a European framework, consistent with GDPR requirements.

## One last habit

If you receive a dubious message, don't reply and [report it](/sms-spam-33700). A free service, with no account and no ads, keeps its promise as long as everyone uses it for what it is: a simple way to send a real message, one you wouldn't be ashamed to stand behind.
