No, Ohayu does not provide a truly unlimited high‑speed eSIM plan for Costa Rica. The plans that carry “Unlimited” in their name limit data to 3 GB per day, after which the speed drops to 1 000 kbps, so they are not unlimited in the sense of high‑speed data without restrictions.
As alternatives, Ohayu offers fixed‑data plans such as 50 GB for 90 days priced at $94.49 or 25 GB monthly for $49.49, both of which allow tethering and provide higher data caps for up to 30 days. Choosing one of these fixed plans can be more cost‑effective than a plan that throttles speed after a daily threshold.
No, Ohayu does not provide eSIM plans for Costa Rica that include a phone number or SMS capability. Their Costa Rica eSIMs are data‑only, so travelers need to use VoIP applications such as WhatsApp, Telegram, or iMessage to make calls or send messages over the data connection.
