Bordersim does not currently offer any eSIM plans for the Czech Republic that include a local phone number or the ability to send or receive SMS. Only data‑only plans are available for that destination. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some countries may block or restrict these services, so users should confirm that the apps they rely on work in the Czech Republic before purchasing.
