4S eSIM does not provide an unlimited data eSIM for Tanzania. Instead, the provider offers fixed‑data plans that can suit a variety of usage needs. For example, a 40 GB plan is available for 365 days at $176.11 USD, while a 20 GB plan can be purchased for 30 days at $39.10 USD. Choosing a fixed data plan can be more cost‑effective for most travelers, unless a user requires an extremely high data volume that exceeds the limits of these offers.
4S eSIM does not provide an eSIM with a local phone number or SMS capability for Tanzania. The provider only offers data‑only eSIM plans for this destination, so travelers will not receive a standard telephony number. However, popular Voice over IP services such as WhatsApp, Telegram, and iMessage can be used over the data connection to make calls and send messages without needing a phone number or SMS function.
4S eSIM provides 27 single‑country data plans specifically for Tanzania and 16 multi‑country plans in which Tanzania is one of the covered destinations. The available plans encompass a wide range of data capacities from 100 MB up to 40 GB, and prices vary between about $1.68 and $176.11. Some of the plans offer a reduced speed option of 512 kbps. These options allow travelers to choose between fixed data amounts and daily data caps to suit different usage needs.
