BetterRoaming does not offer a Slovakian eSIM that includes a phone number or the ability to send and receive SMS messages. All plans sold by the provider for Slovakia are data‑only.
Travelers can use data‑enabled VoIP apps such as WhatsApp, Telegram or iMessage to make calls and send messages, but they should verify that the specific services they rely on are accessible in Slovakia before purchasing, as some destination networks may restrict certain apps or carriers.
