SMSBOX: sovereignty score and 8 European alternatives

SMSBOX is an online SMS platform for sending, receiving and storing text messages, voice messages and other communications. It is operated by MIL'NR3 SAS under the SMSBOX brand. Users work through a web dashboard, an HTTPS API, SMPP or FTP connections, mobile apps or mail-to-SMS. The platform also supports contact-list import, scheduled campaigns, rental of dedicated numbers and keywords, and number validation. The service is offered as a hosted cloud platform accessible over the internet.

MIL'NR3 SAS has its registered office in Carqueiranne, France. The terms of sale state that the platforms and servers are hosted in mainland France, with daily backups and SSL/TLS encryption. The legal notice names the hosting providers OVH and Iliad, both based in France. For recipient data, SMSBOX acts as a processor for its customers. The terms refer to the GDPR and the ePrivacy Directive. For a European organisation, this is a French provider with hosting in France, and the website names no parent company.

Why digital sovereignty matters with SMSBOX

SMSBOX is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so SMSBOX scores best on data residency.

SMSBOX is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs SMSBOX together with your other vendors and gives a total score, a heatmap and the main risk drivers.
