A Zanzibar SIM card is still the cheaper option for most visitors, though an eSIM is catching up fast on convenience if your phone supports one.
Buying a local SIM in Zanzibar isn’t a quick tap-and-go purchase — it requires your passport and, at many counters, your fingerprints, since Tanzania’s SIM registration rules are mandatory and biometric. That single fact is the main argument for an eSIM if your phone supports one: you can be online the moment you land instead of standing in a second queue right after immigration.
Zanzibar SIM card: eSIM vs. Physical SIM
An eSIM wins on convenience: it’s set up before you even leave home, connects automatically on landing if you activate it in advance, and costs roughly $2–5 per GB compared to $3–8 per GB for a physical SIM. The tradeoff is that you keep your home number active alongside it rather than getting a genuine local number, and setup requires a phone that supports eSIM — most phones from the last several years do, but check before you rely on it.
A physical local SIM costs less per GB in absolute terms once you’re past the registration step, gives you an actual Tanzanian number, and is the better choice if you’re staying longer or want a backup in case your eSIM provider has connectivity issues. The registration itself takes 30–60 minutes at a carrier counter, where you’ll hand over your passport and, commonly, a fingerprint scan.
Getting an eSIM
Several eSIM providers sell Tanzania-specific data plans that run on local networks. Typical pricing for data-only plans:
- 1GB / 7 days: around €3.30 ($3.50)
- 3GB / 15 days: around €9 ($9.50)
- 5GB / 30 days: around €13.50 ($14)
- 10GB / 30 days: around €24 ($26)
- 20GB / 30 days: around €44 ($47)
To activate: buy the plan online before you fly, receive a QR code by email, go to your phone’s cellular settings and add the eSIM by scanning the code, then turn on data roaming and select the new eSIM as your data line. Do this on hotel or home Wi-Fi before departure — not at the airport — so the eSIM is ready to connect the moment you land rather than something you’re troubleshooting with the flight’s spotty terminal Wi-Fi.
Getting a Physical Local SIM
Four carriers operate in Tanzania and Zanzibar: Vodacom and Yas are generally considered to have the broadest coverage, including rural and island areas; Airtel is a solid alternative worth comparing current offers against; Halotel tends to be the best-value option when price is the priority. Zantel, historically Zanzibar’s own carrier, has merged with Tigo under one group and remains widely used on the island specifically.
Buy at an official carrier counter — either at the airport or a city store in Stone Town — rather than from an informal street vendor, and test the SIM before you leave the counter to confirm it’s working. Airport prices run higher than city or online prices, so if you’re not in a rush to get online the instant you land, waiting until you reach Stone Town can save a bit. Typical tourist data bundles start around 4GB for a modest cost, with starter top-ups beginning near 1,000 TZS. You’ll need your passport for registration regardless of which carrier or location you choose.
Which One Should You Pick?
If your phone supports eSIM and you want to land already connected — for navigation, ride bookings, or just checking in with people back home — the eSIM is the simpler choice, especially for a trip under two weeks. If you’re staying longer, traveling with a group that needs to coordinate on a local number, or your phone doesn’t support eSIM, a physical SIM from Vodacom or Airtel is the more practical and cost-effective route once you’re past the registration step.
FAQ
Can I buy a SIM card at Zanzibar Airport?
Yes, at official carrier counters, though prices there run higher than in Stone Town. You’ll need your passport, and registration can take 30–60 minutes.
Is an eSIM or physical SIM better for Zanzibar?
An eSIM is more convenient and gets you online immediately on landing; a physical SIM is cheaper per GB and gives you an actual local number, which is better for longer stays.
Do I need my passport to buy a SIM in Zanzibar?
Yes — SIM registration in Tanzania is mandatory and commonly includes a fingerprint scan alongside your passport details.
Which carrier has the best coverage in Zanzibar?
Vodacom and Yas are generally considered to have the broadest coverage, including rural and island areas. Zantel (merged with Tigo) has historically strong coverage on Zanzibar specifically.
How much data do I actually need for a Zanzibar trip?
For a week with normal usage (maps, messaging, some photo uploads), 5–10GB is a reasonable baseline; heavier streaming or hotspot use pushes that higher.
