eSIMNEXA does not provide Czech Republic eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for travelers entering the Czech Republic. Travelers who need to make voice calls or send text messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but these services are not guaranteed to work in all destinations; it is advisable to confirm that the specific apps you rely on are accessible in the Czech Republic before purchasing a plan.
