Sinch: sovereignty score and 8 European alternatives

Sinch is a Swedish provider of cloud communications. Through APIs, businesses can send messages by SMS, RCS, MMS and WhatsApp, and also use email, voice (including SIP trunking), verification and numbers services. On top of these APIs, Sinch offers applications such as a messaging platform, an email platform, a chatbot builder and a contact centre. The company states that it has direct connections to mobile operators. The services are consumed as a cloud platform and through APIs; there is no open-source version of the platform.

Sinch AB is headquartered in Stockholm and listed on Nasdaq Stockholm; its website names regional offices in Atlanta, Stockholm, Singapore and Melbourne. The data processing agreement does not name fixed hosting regions but refers to a separate list of sub-processors. Where data is processed outside the country of the contracting Sinch entity, standard contractual clauses apply; these are governed by Swedish law, with the Swedish authority IMY as the competent supervisory authority. European organisations should consult the current sub-processor list.

Why digital sovereignty matters with Sinch

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

Sinch hosts data in EU, US, APAC. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Sinch 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 Sinch together with your other vendors and gives a total score, a heatmap and the main risk drivers.
