Is there a Zanzibar eSIM?

Not as a separate product, and this is the most common source of confusion. Zanzibar is a semi-autonomous part of Tanzania, so you buy a Tanzania eSIM and it covers Stone Town, the beaches and the mainland. Providers almost never list Zanzibar as its own destination.

Is there mobile coverage on Zanzibar's beaches?

Yes. Nungwi, Kendwa, Paje and Jambiani all have workable 4G, and the resort areas are reasonably well served. Dhow trips and Prison Island excursions lose signal, and Pemba island is thinner than Unguja.

Will a Tanzania eSIM also work on safari?

Yes — the same plan covers the mainland, including the Serengeti and Ngorongoro. Coverage on safari is patchier than on the coast but lodges generally have some signal. If you are combining Zanzibar with a safari, one Tanzania plan covers both.

eSIM for Zanzibar

Short answer

You need a Tanzania eSIM — Zanzibar is part of Tanzania, and that is the single fact most visitors get wrong when buying.

Tanzania plans currently start at $1.35 across 6 providers. Compare all 214 plans →

Zanzibar is a semi-autonomous archipelago within Tanzania, and for connectivity purposes it is simply Tanzania. This trips people up constantly: they search for a Zanzibar eSIM, find nothing, and assume none exists. Buy a Tanzania plan and it works across Stone Town, the beaches and the mainland alike.

How much data do you need in Zanzibar?

Trip type	Suggested	Why
Beach week	3–5 GB	Resort and guesthouse wifi covers a lot, though it is often slow. Data handles maps and messaging.
Zanzibar plus a mainland safari	10 GB	The same Tanzania plan covers the Serengeti and Ngorongoro legs, where you will want it more.
Remote work	20 GB+	Island wifi is inconsistent and power cuts affect it. Mobile data is the more reliable option.

Coverage in Zanzibar

Vodacom, Airtel Tanzania and Zantel cover the islands. Stone Town, Nungwi, Kendwa, Paje and Jambiani all have workable 4G, and the coastal resort areas are well served because tourism depends on it. The interior and the smaller islands — Pemba in particular — are thinner. Coverage on dhow trips and to Prison Island drops out.

Arriving in Zanzibar

ZNZ is small and the transfer to the beach areas takes up to an hour and a half depending on which coast. Having data working on landing helps, since taxi pricing is negotiated and knowing the going rate is useful.

What catches people out

Buy a Tanzania plan, not a Zanzibar one

Zanzibar is part of Tanzania and is almost never listed separately by eSIM providers. Searching for it as its own country is why people conclude no plan exists.

Power cuts affect wifi more than mobile

Grid supply on the islands is unreliable and guesthouse wifi goes down with it. Mobile data often keeps working when the wifi does not.

Pemba and the smaller islands are thinner

Coverage concentrates on Unguja, the main island. If you are heading to Pemba, expect gaps.
