nextSIM eSIM Data Plans for Slovenia

NextSIM does not provide a truly unlimited data eSIM for Slovenia. All plans listed under the “Unlimited” umbrella specify a data cap—either 1GB or 2GB per day—after which the connection speed is throttled to 512 kbps or 2000 kbps.

Users who need large amounts of high‑speed data can choose from the fixed‑data options. For instance, nextSIM offers a 100GB plan for 30 days and a 50GB plan for 30 days, both with no reduced speed after a certain threshold. These fixed plans can be more cost‑effective for heavy data users, while the “Unlimited” plans may be suitable for short stays when a lower daily cap is acceptable.

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 provides a mix of single‑country and multi‑country eSIMs that include Slovenia. In the single‑country category there are 33 different plans available, while the multi‑country lineup offers 58 separate options that cover Slovenia among other destinations. Plans vary from a few gigabytes up to 100 GB, price points spanning from about $1.86 to nearly $1, 275.95, and validity periods ranging from 1 day to 365 days. Customers can choose between fixed data caps, which offer a single cumulative allowance for the entire validity period, and daily data‑cap plans, which provide a set amount of data each day.
