The network Costa Rica calls home.
Ring is the SUTEL-licensed Costa Rican carrier operating the 100% IP infrastructure behind millions of calls, messages and megabytes a day — for wholesale carriers, enterprises and Costa Rican businesses.
Costa Rica deserves a better network. So we built it — cable by cable, route by route, call by call.
We keep the wires.
A network isn't rented — it's designed, operated and watched. Ring has done that since 2019, with an owned core, redundant POPs and direct interconnect to the national telephone network.
Every product is an API.
Voice, SMS, numbering, eSIM, PBX — every product exposes its own documented API, SDKs and webhooks. No tickets to provision, no email threads to escalate: if it happens on the network, it happens through an HTTP call.
Run from San José.
This is where Ring lives — where the network gets designed, where email gets answered, where tickets get closed. 24/7 email support with AI-assisted triage; when something hits the core, a Costa Rican engineer takes it from there.
San José, Costa Rica.

Licensed. Independent. Costa Rican-owned.
Ring® has been a SUTEL-licensed carrier since 2019. We don't resell, we don't outsource the core, and we're nobody's branch office. When you sign a contract, you sign with the team that designs the network. When a call drops, you call the team that brings it back up.
A brand for every use case.
Each product is a focused brand with its own dashboard, API and docs. All ride the same network, with the same support and the same regulatory backing.
