Billion Connect does not offer eSIM plans that include a phone number or SMS capability for travelers heading to the Czech Republic. The provider’s catalog for this destination contains only data‑only eSIM options, so users will not receive inbound or outbound voice or text services through a local number.
Travelers who need to stay in touch can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, they should confirm that these apps function properly in the Czech Republic, as some destinations may block or restrict access to certain VoIP services.
