ZenSim does not provide a truly unlimited data eSIM for Tanzania. The only plan that carries “Unlimited” in its name is the Tanzania Unlimited STANDARD – 5 Days, which offers 3GB per day and reduces speed to 1000kbps after the daily limit is reached. This is a fixed data plan, not an unlimited one.
Travelers who need more data can choose from ZenSim’s fixed data plans, such as the Tanzania 20GB – 15 Days or the Tanzania 20GB – 30 Days plan. These plans give a set amount of high‑speed data that must be used within the validity period, and they can be more cost‑effective for users who do not require continuous unlimited data.
