TropiTrade does not provide an unlimited data eSIM for Tanzania. All of the plans listed for Tanzania are fixed‑data bundles, each with a hard limit: 20GB, 10GB, 5GB, and 3GB, all of which are valid for 30 days.
If a traveler wants a large data allowance within a fixed period, the 20GB 30‑day plan is the largest option available. Fixed data plans can be more cost‑effective unless a user is an extremely heavy data consumer who needs truly unlimited usage.
