Buying a SIM Card in Tanzania

By Lauren Juliff Get Connected2 Comments

The dazzling white-sand beaches of Zanzibar, the snow-capped summit of Mount Kilimanjaro, the endless plains of the Serengeti. Tanzania has a wealth of attractions to impress even the most jaded of travelers.

It’s a large country, though, and while you’ll find Wi-Fi in the majority of tourist destinations, it’s never going to set speed records.

Fortunately, getting set up and staying connected within the country with a local SIM card is easy and inexpensive, and data speeds can be surprisingly fast.

Here’s everything you need to know about buying a SIM card in Tanzania.

  • Need travel insurance for your time in Tanzania? We currently use HeyMondo, thanks to its comprehensive coverage options, competitive pricing, and the ability to buy or renew a policy while outside your home country. Residents of most countries get a discount with this link.


  • We recommend Vodacom for the majority of travelers to Tanzania
  • If you’re spending significant time in the Serengeti, consider Airtel instead
  • If you’re only visiting Zanzibar, go with Zantel
  • A Tanzania eSIM is often the best option if your device supports it

There are five network providers operating in the country. In order of market share, these are Vodacom, Airtel, Tigo, Zantel, and Halotel. Vodacom has the widest coverage in the country, and Zantel has the best coverage for Zanzibar.

If you’re going to be traveling across large parts of Tanzania, Vodacom has the greatest all-round coverage and is the best choice. If you’ll be spending the majority of your time in the Serengeti and Ngorongoro, however, Airtel has better coverage there, with slightly cheaper prices than Vodacom.

For those mostly visiting Zanzibar and spending little time on the mainland, Zantel is the best provider on the island. It’s not great in the rest of the country, however.

While this article is about buying physical SIM cards, if you have a recent iPhone or other supported device, the best way to get connected in Tanzania may be to buy an eSIM instead.

We've written an explainer of what eSIMs are all about if you're not familiar with them. Because they're software rather than a plastic card, you can buy before you leave home, avoid the hassle of kiosks and phone stores entirely, and get connected as soon as you land.

These days, we use aloSIM: easy to buy and set up, it's a simple, low-cost way of staying connected when you travel. You'll get a discount on your first purchase with the code TMA.

How to Buy a Prepaid SIM Card in Tanzania

The easiest way to purchase a SIM card in Tanzania is to do so immediately outside the international terminal at Dar es Salaam airport. Upon exiting the arrivals area, you’ll find yourself face to face with a Vodacom store, and it’ll take just five minutes to get set up with a SIM card.

Around the country, just look for a vendor sitting beneath an umbrella with the provider’s branding on it. Keep in mind that you’ll need your passport for a SIM card purchase from any network, so make sure you’ve got it with you.

Tanzania introduced new SIM card registration requirements in 2019, but in general they have affected local residents more than visitors. For now at least, you should still be able to register your SIM at an official store or registration agent using only your passport.

If you’re flying into Zanzibar, you’ll be able to pick up a Zantel SIM at the airport on the island. You can also get one at Darajani Bazaar outside of the old town in Stone Town. Just look for the group of men under umbrellas.

Be on your guard for scammers: in Stone Town, I was unfortunately scammed by a local on my hunt for a SIM card. None of the stores in town sell them (that’s why it’s best to get one in Dar es Salaam or at Zanzibar’s airport when you fly in), so you’ll need to head to the outskirts in order to find a vendor.

If any friendly local offers to help you navigate the SIM card buying process, don’t trust them. I was charged 10x the standard price because I believed the guy was trying to help me out, and I hadn’t yet memorized the exchange rate.

Lesson learned.

Prepaid SIM Costs

SIM cards and data are inexpensive in Tanzania (providing you don’t get scammed!).

A Vodacom SIM card and package valid for a week costs 15,000 TZS (~$6.50.) This includes 1000 TZS for the SIM card, 4000 TZS to cut it down to nanoSIM size, and 10,000 TZS for 4.5 GB of data, 200 minutes of domestic calls, and 100 domestic text messages.

Zantel SIM cards are also 1000 TZS. 1.2 GB of data valid for a week costs another 5000 TZS.

Topping Up

To top-up your Vodacom SIM card, simply look for a store with Vodacom advertising outside and ask to buy credit. You’ll be given a scratchcard with a code that you then need to enter into your phone to top-up.

Dial *104*scratchcode# to top up your phone with credit, then *148*00# to select a data bundle.

To top up Zantel SIM cards, the process is similar: pick up a scratchcard at any store with Zantel branding. Once you’ve got your code, enter: *149*scratchcode# to add the credit, and *149*07# to select a data bundle.

Coverage and Data Speeds

Let’s start with Vodacom.

Speeds were very good on the mainland: I got 13Mbps download in Dar es Salaam, and over 16Mbps in Kilimanjaro. Vodacom has the best coverage of any provider in the country, although you’ll typically only get faster data speeds in the most-visited parts of the country.

And now Zantel.

In Zanzibar, as you would expect, speeds were fast and coverage was fantastic. I averaged around 8Mbps on the island.

On the mainland, Zantel roams on the Tigo network, and speeds were much slower. I was only able to get 1.41Mbps in Dar es Salaam, and 2.86Mbps in Kilimanjaro.

    I have been told that foreigners are no longer allowed to buy sims in Tanzania. Comments?

      I haven’t seen anything to that effect at this stage. New regulations came in earlier this year, but this article suggests foreigners can register a SIM like anyone else as long as they have their passport with a valid visa in it. According to the text of the regulations linked at the bottom of that article you may need a certified copy of your passport, which could make things more difficult. I have no information on whether that aspect is actually a hard and fast requirement, however.
