No, eSIMatrix does not provide a Costa Rica eSIM that includes a phone number or SMS capability. All plans sold by eSIMatrix for Costa Rica are data‑only, so travelers cannot make or receive regular cell calls or text messages with a local number. However, over the data connection, VoIP services such as WhatsApp, Telegram, and iMessage can generally be used for calling and messaging, although some destinations may block or restrict certain apps, so travelers should verify access to the apps they need before purchasing.
