ByteSIM does not provide a true unlimited‑data eSIM for Tunisia. All of its Tunisian plans list a fixed data cap; the plans marked “Unlimited” in the name actually supply 1 GB per day and reduce speed to 10000 kbps after that limit.
Travelers who need more data can choose from ByteSIM’s fixed data plans, such as the 50GB bundles that are available for 3, 5, 7, 10, or 15 days. These options give a large allowance of high‑speed data and can be more cost‑effective unless you are an extremely heavy data consumer.
