nextSIM eSIM Data Plans for Slovenia

nextSIM does not provide a truly unlimited high‑speed data plan for Slovenia. All plans labeled “Unlimited” in their catalogue contain a fixed data allowance—typically 1 GB or 2 GB—with a reduced speed (e.g., 512 kbps or 2000 kbps) once the cap is reached. For travelers who need larger amounts of data, nextSIM offers fixed‑data eSIMs such as the 100 GB 30 days standard plan or the 50 GB 30 days options, which allow high‑speed access throughout the validity period without throttling. Choosing a fixed‑data plan can be more cost‑effective for heavy data users than a plan that limits speed after a small data cap.

nextSIM does not offer eSIM plans for Slovenia that include a phone number or SMS capability. Only data‑only eSIM plans are available for that country. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calling and messaging.

nextSIM provides both single‑coverage and multi‑coverage options that include Slovenia. In total, the provider lists 47 single‑country plans and 107 multi‑country plans across its catalogue. The plans vary widely: data caps range from 1 GB up to 100 GB, prices span from $1.54 to $1, 299.92, and validity periods run from 1 day to 365 days. Some plans feature daily data caps while others offer fixed data amounts, depending on the selected package.
