shibaSIM does not provide a truly unlimited data eSIM for Tanzania. All available plans list a fixed daily high‑speed data allowance—0.5 GB, 1 GB, or 2 GB per day—with a reduced speed of 128 kbps applied once the daily limit is reached. The provider’s notes confirm that the data caps are hard limits for high‑speed use, after which the speed is throttled.
Travelers who need more data can choose a fixed data plan, such as the 2 GB/day plan that remains valid for five days or the 1 GB/day plan that stays active for fifteen days. These fixed plans give a larger overall data allowance and can be more cost‑effective for those who use a substantial amount of high‑speed data during their stay in Tanzania.
