ZenSim eSIM Data Plans for Tanzania

ZenSim does not provide a truly unlimited data eSIM for Tanzania. The only plan that contains “Unlimited” in its name—Tanzania Unlimited STANDARD‑5 Days—offers 3GB/day of high‑speed data and, after the daily quota is used, the speed is throttled to 1000 kbps.

For travelers needing more data, ZenSim offers fixed data plans such as Tanzania 20 GB for 15 days or Tanzania 20 GB for 30 days. These plans provide a set amount of high‑speed data that must be used within the specified validity period, and they can be more cost‑effective unless a user requires continuous unlimited data.

ZenSim does not offer a Tanzanian eSIM plan that includes a phone number or SMS capability. All ZenSim eSIM offerings for Tanzania are data only and lack inbound or outbound voice or text messaging services.

Travelers who require voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though some destinations may block or restrict access to these apps, so users should verify that the services they rely on are accessible in Tanzania before purchasing.

ZenSim currently offers ten single‐country data plans for Tanzania, with no multi‑country options available. The plans range in price from about $10 to $80 and provide data caps between 1 GB and 20 GB. Coverage validity spans 5 to 30 days. Of the ten plans, one includes a daily data cap feature while the remaining nine are fixed‑data plans. All plans permit tethering.
