ByteSIM does not provide truly unlimited high‑speed data plans for Slovenia. The plans that carry the name “Slovenia Unlimited Data” actually contain a data cap of 1 GB per day; once the limit is reached the speed drops to 10240 kbps. This means the name reflects a daily allowance rather than unlimited data usage.
If you need a larger data allowance, ByteSIM offers fixed‑data plans. For example, a 50 GB plan is available for 3 to 15 days, granting a substantial amount of data without the speed reduction that occurs after the daily cap of the “Unlimited” options. These fixed‑data plans may be a more cost‑effective choice for travelers who expect to use a significant amount of data.
