No, nextSIM does not provide a true unlimited data eSIM for Slovakia. All plans listed as “Unlimited” in the catalog actually cap the high‑speed data at 1 GB or 2 GB, after which the speed is throttled to 512 kbps or 2000 kbps. For travelers who need more data, nextSIM offers fixed‑data alternatives in Slovakia, such as the 100 GB 30 days standard plan for $61.94, the 50 GB 30 days standard plan for $31.29, and the 50 GB 30 days economy plan for $27.76. These fixed plans give a larger data allowance without the speed reduction that applies to the “Unlimited” options, making them more suitable for users who consume a lot of data while visiting Slovakia.
nextSIM does not provide any Slovakia eSIM plan that includes a local phone number or SMS capability. All plans sold by nextSIM for Slovakia are data‑only, so travelers will not receive inbound or outbound voice or text services from a native mobile network.
Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, these services may be restricted or blocked in some destinations, so it is advisable to confirm that the apps you rely on work in Slovakia before purchasing a plan.
NextSIM offers 38 single‑country data plans that provide coverage solely in Slovakia and an additional 115 plans that bundle Slovakia with other destinations. The available plans span a price range from about $1.54 to $1, 289.42 and a data cap range between 1 GB and 100 GB. Among the catalog, some plans are fixed‑data, allocating a set amount of data for the entire validity period, while others are daily‑cap plans that grant a specific data allowance each day during the active period. This variety allows travelers to choose from low‑cost 1 GB packages to more premium 100 GB options that may be useful for longer stays or higher data usage.
