description: 'Syniverse is a United States headquartered wholesale telecommunications company that sits between mobile network
  operators rather than in front of consumers. Its mobility business runs inter-carrier roaming, IPX network and signaling,
  5G SEPP, clearing and settlement, global SIM and satellite roaming for carriers, and none of that carrier-side estate is
  exposed as a public API. Its messaging business is the opposite: an A2P/CPaaS aggregator selling SMS, MMS, RCS, WhatsApp,
  push, voice, 10DLC campaign registration, messaging trust/anti-spam and mobile identity services to enterprises, and it
  is published through a genuine self-serve developer portal, the Syniverse Developer Community (SDC), where anyone can sign
  up for a free API key, read the docs, and download eleven Redoc-rendered OpenAPI/Swagger definitions. On network APIs Syniverse
  is a channel, not a source — it joined GSMA Open Gateway in April 2025 as a channel partner and announced an integration
  with Aduna in June 2025, but no CAMARA-defined API is documented or callable on its developer portal today.'
