BetterRoaming does not offer any eSIM plans for Slovenia that include a phone number or SMS capability. Travelers who need a local number or the ability to send text messages should look for alternative providers that offer telephony in the country. Instead, BetterRoaming’s Slovenia plans provide only data, which allows the use of VoIP applications such as WhatsApp, Telegram, or iMessage for voice and messaging. However, some destinations may block or restrict certain VoIP services, so it is advisable to verify that the apps you rely on are accessible in Slovenia before making a purchase.
