simpleSIM does not provide a truly unlimited data eSIM for Serbia. The plans that carry the “Unlimited” name actually grant 1GB of high‑speed data per day and, once that daily limit is reached, the speed is reduced to 512 kbps. Therefore, the data allowance is capped and not unlimited.
Travelers who need more data can choose from simpleSIM’s fixed data plans. For example, the 20GB plan is valid for 30 days and the 10GB plan is also valid for 30 days, both offering higher data allowances without the speed reduction that applies to the “Unlimited” plans. These fixed plans may be more cost‑effective for users who consume a substantial amount of data.
