ByteSIM does not provide a truly unlimited data eSIM for Serbia. The plans that carry the word “Unlimited” in their name actually offer 1GB per day, and once that amount is reached the speed is throttled to 10000kbps. Therefore, they are not unlimited in the sense of providing high‑speed data without limits.
Travelers who need a larger data allowance can choose ByteSIM’s fixed data plans, such as the 50GB options that are valid for 3, 5, 7, 10, or 30 days. These plans give a fixed amount of high‑speed data and can be more cost‑effective for users who consume a lot of data during their stay in Serbia.
