XCarrier: sovereignty score and 8 European alternatives

XCarrier is a software platform for the wholesale telecom market from Carrier Call AG in Oberflachs, Switzerland. It is aimed at carriers and managed service providers and bundles three areas: traffic management (contract parameterisation, bilateral agreements, least-cost and quality-based routing, switch provisioning, dashboards), billing (call data record conversion, rating, invoicing, reconciliation of incoming carrier invoices) and protection against spam, spoofing and fraud. The vendor offers XCarrier as a multi-tenant cloud service and, for security-conscious operators, as an on-premises installation.

Carrier Call AG is a Swiss company, and its imprint names no foreign parent. The website does not state where the cloud service is hosted. Switzerland is assumed from the company seat, so ask the vendor to confirm the location. Call data records contain personal data about end users, so a carrier should also clarify roles, sub-processors and retention. The on-premises option keeps data in the operator's own environment. Switzerland is not in the EU but is an EFTA country with an EU adequacy decision.

Why digital sovereignty matters with XCarrier

XCarrier is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

XCarrier hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

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