GigSky does not provide eSIM plans for the Czech Republic that include a phone number or SMS capability. Travelers who need a local number or text messaging will need to look for other providers that offer telephony services in the Czech Republic. However, they can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the GigSky data connection for calls and messages. Some destinations may block or restrict certain VoIP services, so it is advisable to verify that the apps you rely on are accessible in the Czech Republic before purchasing a GigSky plan.
