GIGAGO does not provide an eSIM for the Czech Republic that includes a local phone number or SMS capability. The only plans available from GIGAGO for this destination are data‑only, offering high‑speed internet via the network but no inbound or outbound voice or text services. Travelers who need to make voice calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though they should verify that these apps are not blocked or restricted in the Czech Republic before purchasing.
