Companies like British Airways, H&M, and Google have faced multi-million-euro fines for data breaches or unlawful data processing.

Using non-compliant France mobile uae consumer mobile number list number lists exposes organizations to significant legal, financial, and reputational risks.

Legitimate Interest: A Possible Alternative?
Some organizations rely on “legitimate interest” as a legal basis for processing mobile numbers. While GDPR allows this, it comes with conditions:

You must conduct a Legitimate Interest Assessment (LIA).

The interests of the organization must not override the rights and freedoms of the data subject.

The use must be necessary and proportional.

In practice, relying on legitimate interest for unsolicited SMS marketing or cold calling in France is high-risk, especially without a clear opt-out mechanism or prior relationship.

France-Specific Regulations: CNIL and E-Privacy Directive
In addition to GDPR, France has its own data protection authority — the CNIL (Commission Nationale de l’Informatique et des Libertés) — which enforces data laws nationally. The CNIL has issued additional guidance on electronic communications, including:

Opt-in is mandatory for all B2C marketing via SMS, calls, or email.

Businesses must retain proof of consent and make opt-out options available.

Cold SMS marketing is prohibited unless the user has opted in.

So, even if you think you’re compliant with general GDPR principles, if your France mobile number list is used for SMS campaigns without consent, you’re likely violating both GDPR and CNIL rules.
