CPaaS
GMS (Global Message Services)
Swiss messaging company serving both mobile operators and enterprises: A2P traffic and firewalls for carriers, and a single API for SMS, Viber, WhatsApp and push.
A carrier-side messaging company with an enterprise CPaaS, named a Niche Player by Gartner in 2026.
GMS was founded in 2006 and is based in Baar, Switzerland. On the operator side it handles A2P traffic exchange and network protection; on the enterprise side its CPaaS sends SMS, Viber, WhatsApp and push messages through one API, with fallback chains such as push then Viber then SMS in a single request and delivery reports to a callback URL. Its product pages also list RCS. Worth a look when you want cascading channels from a provider with deep operator connections.
Where it shines
- Multi-channel fallback (push, Viber, SMS) in a single API request
- Delivery reports to a callback URL, documented publicly
Check before signing
