MSG91: sovereignty score and 8 European alternatives

MSG91 is a cloud communication platform offering APIs for SMS, OTP and two-factor verification, WhatsApp, RCS, email and voice. Its products include a multi-channel messaging API, campaign automation and customer data tools. Customers use the service through a web dashboard and API integrations, delivered as a cloud service.

According to the privacy policy, the service is operated by Walkover Web Solutions Pvt Ltd, based in Indore, India. The policy states that the service is hosted in the United States or Germany, and it lists AWS regions in the US, the EU and India among its hosting providers. Because the operator is established in India, Indian legal access powers may apply, and a European organisation should confirm in the contract which hosting region is used. The policy describes MSG91 as a processor for its clients and commits to GDPR requirements for international transfers.

Why digital sovereignty matters with MSG91

MSG91 is headquartered in IN, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

MSG91 hosts data in US, EU, OTHER. 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.

MSG91 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 MSG91 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
