eSimfly does not provide a truly unlimited data eSIM for Tanzania. The only plans with the word “Unlimited” in their name give a data cap of 3GB per day for 3‑30 days; after the daily limit is reached, the speed is reduced to 1000kbps.
If a traveler needs a larger, fixed data allowance they can choose from eSimfly’s fixed data plans, such as the Discover Global 20 GB 30 days plan priced at $48.18 USD or the Discover Global 10 GB 30 days plan for $29.70 USD. These plans offer 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 are heavy but not unlimited data consumers.
