Best Connect eSIM does not provide eSIM plans that include a local phone number or SMS service for Slovakia. Travelers who need a phone number or SMS capability in Slovakia will need to look for a different provider or rely on data‑only usage.
Over a data‑only eSIM, VoIP applications such as WhatsApp, Telegram, and iMessage can normally be used for voice calls and messaging. However, some destinations may block or restrict access to certain VoIP services, so it is advisable to check that the apps you plan to use are available in Slovakia before purchasing a data‑only plan.
