ZenSim eSIM Data Plans for Tanzania

ZenSim does not provide a truly unlimited data eSIM plan for Tanzania. Their highest‑capacity plan is the Tanzania Unlimited STANDARD – 5 Days, which offers 3GB of high‑speed data per day and is not an unlimited plan; after this amount the service is no longer considered unlimited. Travelers who need substantial data can choose from fixed‑data alternatives such as the Tanzania 20GB – 15 Days, Tanzania 20GB – 30 Days, Tanzania 10GB – 15 Days, Tanzania 10GB – 30 Days, or Tanzania 5GB – 15 Days plans. These options provide larger data allowances within a single validity period and can be more cost‑effective for most users.

ZenSim does not provide any Tanzania eSIM plans that include a phone number or SMS capability. All of its available offers for Tanzania are data‑only eSIMs.

Because the plans lack a local voice and messaging number, travelers rely on internet‑based applications—such as WhatsApp, Telegram, or iMessage—to make calls and send texts. These VoIP apps work over the data connection provided by the eSIM.

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.
