Simsima eSIM Data Plans for Tanzania

Simsima does not provide a truly unlimited high‑speed data plan for Tanzania. The plans that carry the “Unlimited” name are limited to 3 GB per day; once this amount is used, the speed is reduced to 1000 kbps.

If you need a larger data allowance, Simsima offers fixed plans such as the 20 GB‑30 days plan, priced at $40.65 USD for Tanzania, and a 10 GB‑30 days plan for $24.19 USD. These options give you a fixed amount of high‑speed data that can be used anytime within the validity period and are often more cost‑effective for most travelers.

Simsima does not provide Tanzania eSIM plans that include a phone number or SMS capability. Travelers who need voice or text messaging will have to rely on internet‑based services such as WhatsApp, Telegram, or iMessage via the data connection, although some destinations may block or limit these apps, so it is wise to confirm their availability in Tanzania before purchasing a plan.

Simsima provides 11 single‑country data plans and 19 multi‑country data plans that can be used in Tanzania.
Among the offerings, there are 8 plans with a daily data cap and 22 with a fixed data amount.
The plans cover a price range from about $1.50 to $110.94 and data caps ranging from 100 MB up to 20 GB, with validity periods between 5 and 365 days.
