4S eSIM does not provide a true unlimited data plan for Slovakia. All listed Slovakian plans have a defined data cap, such as 3 GB, 5 GB, 10 GB, 20 GB, 30 GB or 50 GB, and they are labeled “Unlimited” only because no additional charges are applied once the data allowance is reached. After the capped amount is used, the speed is throttled to 1 000 kbps.
Customers who need large amounts of data can choose one of the fixed‑data options, for example the 3 GB plan that costs $2.38 USD for 1 day or the 50 GB plan that costs $20.36 USD for 5 days. These plans provide a higher data allowance than typical pre‑paid eSIMs and may be more cost‑effective for heavy data users who do not require an uncapped data service.
4S eSIM does not provide Slovakia eSIM plans that include a phone number or SMS service. Travelers can only purchase data‑only plans for the country. They can use VoIP apps such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages, but some destinations may limit access to certain VoIP services. Travelers should verify that the apps they rely on are available in Slovakia before purchasing.
The dataset shows that 4S eSIM has 54 single‑country plans and 108 multi‑country plans globally, but it does not list how many of those cover Slovakia specifically. Therefore, the exact number of data plans available for Slovakia cannot be determined from the provided information.
