Skyalo does not provide eSIM plans that include a local phone number or SMS functionality for Costa Rica. The provider offers only data‑only eSIM options in that destination.
Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict certain apps or services, so it is advisable to confirm that the apps you rely on are accessible in Costa Rica before purchasing a plan.
