JamboSim eSIM Data Plans for Tanzania

JamboSim’s plans marketed as “Unlimited” for Tanzania actually offer 3 GB of high‑speed data per day; after that limit the speed is reduced to 1000 kbps. Because the data allowance is capped in this way the plans are not truly unlimited.

Instead of an unlimited offer, JamboSim provides fixed‑data options. For example, a 20 GB plan valid for 30 days costs $37.99 and gives continuous high‑speed data without throttling. Choosing a fixed‑data plan can be more cost‑effective for travelers who expect to use more than the 3 GB/day that the so‑called unlimited plans provide.

JamboSim provides eSIM plans that include a phone number and outbound SMS capability for travel in Tanzania. The Global+ plans range from 1 GB for 7 days at $11.99 USD to 20 GB for 365 days at $105.99 USD, with validity options of 7 days, 15 days, 30 days, 60 days, 180 days and 365 days. Each plan uses a dialing code of +1, allows outbound voice calls and outbound SMS, but does not include inbound voice or inbound SMS. Travelers should check with JamboSim directly to confirm any specific functionality they need.

JamboSim offers a range of plans that cover both Tanzania alone and multiple countries simultaneously. For single‑country coverage there are 12 distinct plans, while for travelers who want broader regional access there are 48 multi‑country options. The available plans span a price range from $1.99 to $125.99 and provide data amounts between 200 MB and 20 GB, with validity periods that can be as short as one day or extend up to 365 days. Among these plans, some are structured with a daily data cap, meaning a fixed amount of data is available each day for the chosen duration, whereas others use a fixed data cap model, delivering a one‑time data allotment that lasts for the entire validity period.
