Alodata does not provide a true unlimited data eSIM for Serbia; all plans that carry the word “Unlimited” in their name actually include a data cap of 1 GB per day (or 1 GB total for the 1‑day variant). After the set amount of high‑speed data is used, the connection automatically throttles to 1280 kbps, so the data allowance is not unlimited.
If you need larger amounts of high‑speed data, alodata offers fixed‑cap plans such as a 100 GB package for 30 days or a 50 GB package for 30 days, both with no speed reduction. These fixed plans can be more cost effective for travelers who expect to use more data than the daily cap on the “Unlimited” plans would allow.
