nextSIM eSIM Data Plans for Slovenia

No, nextSIM does not provide a truly unlimited eSIM plan for Slovenia. All plans that carry the word “Unlimited” in their name actually deliver a capped amount of high‑speed data, after which the speed is throttled – for example “Unlim­ited Standard 1 Day Slovenia” offers 1 GB of high‑speed data per day and reduces speed to 512 kbps once the limit is reached.

If you need large amounts of data for a stay in Slovenia, nextSIM offers fixed‑data plans. A 50‑GB plan is available for 30 days and a 40‑GB plan for the same period, both featuring 3G, 4G, and 5G coverage. These plans provide a defined data allowance and may be more cost‑effective for heavy users than the capped “Unlimited” options.

nextSIM does not offer an eSIM for Slovenia that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for Slovenia.

Travelers can still use messaging and voice applications such as WhatsApp, Telegram, and iMessage over the data connection, allowing them to communicate without a local phone number or SMS service.

nextSIM offers a mix of single‑country and multi‑country eSIM options for travelers heading to Slovenia. There are 18 single‑country plans that cover only Slovenia and 48 multi‑country plans that include Slovenia among several other destinations. The offerings span a wide price range, from as low as $2.11 up to $1,292.01, and the data caps vary from 1 GB to 50 GB. Users can choose between daily data‑cap plans—34 options that refresh daily—and fixed‑data‑cap plans—32 options that provide a set amount of data for the entire validity period. This diversity lets travelers find a plan that matches both budget and usage needs.
