MTX Connect does not provide a Slovakia eSIM that includes a phone number, voice calls, or SMS capability. Travelers can only purchase data‑only eSIM plans from this provider for Slovakia.
Without a local phone number or SMS service, users can still reach destination contacts by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict or block specific apps or VoIP services, so travelers should confirm that the messaging or calling apps they rely on are accessible in Slovakia before purchasing.
