Internet in Zanzibar 2026/2027 – eSIM, Local SIM or Roaming? What Works Best on Holiday?

Zanzibar is associated with white-sand beaches, the turquoise Indian Ocean, and holidays far away from everyday life. That does not mean, however, that you can completely forget about internet access. You may need it as soon as you leave the airport – to contact your hotel or driver, use maps, check reservations, message someone, or upload photos from your trip.

There are several ways to arrange internet in Zanzibar. The main options are eSIM, a local SIM card, roaming with a Polish mobile operator, and WiFi in hotels and restaurants. The differences concern not only price, but also convenience, available data allowances, and the time needed to activate the service.

In 2026, the situation is even more interesting because Polish operators are increasingly offering special data packages for travel outside the European Union. This still does not mean that standard roaming in Zanzibar works the same way as it does during a holiday in Italy or Spain. So let’s see which internet option is best in Zanzibar in 2026/2027 and what works best for a one- or two-week holiday.

How does internet in Zanzibar work in 2026?

Zanzibar is part of Tanzania, so when choosing a SIM card, eSIM, or roaming package, you should usually look for offers that cover Tanzania.

Several major mobile operators are active on the Tanzanian market. According to data from the TCRA regulator, the main mobile internet providers include Vodacom, Yas, Airtel, and Halotel. Vodacom and Yas together account for more than half of the mobile internet market in Tanzania.

Yas is particularly important in Zanzibar. The operator is continuing to develop infrastructure on Unguja and Pemba, including in tourist and business areas. In 2026, the company reported further investments in its network across the archipelago.

In popular tourist destinations such as:

• Stone Town,
• Nungwi,
• Kendwa,
• Paje,
• Jambiani,
• the airport area,
• larger resorts on Unguja,

access to 4G mobile internet is generally easier than in less urbanised parts of the islands. However, local connection quality can depend on the specific operator, network congestion, and the location of your hotel.

That is why it is not a good idea to assume that hotel WiFi will be the only internet connection you need.

eSIM for Zanzibar – the most convenient internet from the moment you arrive?

For many travellers, an eSIM for Zanzibar is the easiest way to arrange internet before departure.

An eSIM is a digital SIM profile installed directly on a compatible phone. You do not need to open the SIM tray, remove your Polish SIM card, or visit a local operator store.

You can buy the package while still in Poland, install it before travelling, and then use it after arriving in Zanzibar according to the activation rules of your provider.

Why is eSIM useful in Zanzibar?

Its biggest advantage is convenience.

After a long journey, the last thing many travellers want to do is look for a SIM card shop and go through the registration process.

With an eSIM, the whole process can be prepared in advance:

1. choose a data package covering Tanzania/Zanzibar,
2. buy an eSIM online,
3. install the profile on your phone,
4. set the eSIM as your mobile data line,
5. after landing, enable the profile and data roaming for the eSIM,
6. wait for the phone to connect to a supported local network.

This means mobile internet abroad can be available almost from the beginning of your stay.

It is especially useful if you need to find your driver, contact the hotel, check the route, or open a booking confirmation after arrival.

Do you need to enable data roaming with eSIM?

With many travel eSIMs – yes.

Although this may sound contradictory to the idea of avoiding expensive roaming, travel eSIMs often connect to local partner networks through roaming agreements.

That is why you may need to enable Data Roaming on the eSIM profile.

At the same time, it is a good idea to disable mobile data on your primary Polish SIM card. This reduces the risk of your phone accidentally using expensive roaming from your domestic operator.

Local SIM card in Zanzibar – is it worth buying one?

The second option is a local SIM card.

Its main advantage can be the attractive price of data packages, especially for longer stays or intensive internet use. Local plans can offer a large amount of data for a relatively low price.

However, you need to take registration formalities into account.

How do you buy a local SIM card in Zanzibar?

SIM cards in Tanzania are subject to mandatory registration. Tourists may be required to show a travel document, and the registration process may include identity verification and biometric procedures.

Vodacom officially states that visitors to Tanzania must present appropriate travel documents and complete biometric verification during registration. Similar requirements apply to Airtel customers.

The Tanzanian regulator TCRA also states that a tourist SIM card is registered using a travel document, and its validity may be linked to the visitor’s legal period of stay in the country.

In practice, this means buying a local SIM is less anonymous and less immediate than purchasing an eSIM online.

The safest approach is to buy a SIM from an official operator store or authorised retailer and, before leaving, check:

• whether the SIM has been activated,
• whether the data package is active,
• whether the phone has internet access,
• whether the APN settings are correct.

Local SIM cards can also be found at sales points in popular tourist areas and near the airport.

Who is a local SIM best for?

It is a good option mainly for travellers who:

• are staying in Zanzibar for longer,
• need a lot of mobile data,
• want a local phone number,
• do not have an eSIM-compatible phone,
• do not mind buying and registering a SIM after arrival.

If you are visiting for 7–14 days and convenience is your main priority, the lower cost of a local SIM may not compensate for the time spent buying and configuring it.

Roaming in Zanzibar – how much does internet from a Polish SIM cost?

Zanzibar is outside the European Union and the European Economic Area. Roam Like at Home does not apply here.

You should therefore not assume that your Polish data allowance will automatically work in Zanzibar under the same conditions.

The situation in 2026 is better than it was a few years ago because some Polish mobile operators now offer additional data packages that cover Tanzania.

For example, T-Mobile includes Tanzania in its “World” zone and offers packages such as:

These prices reflect the T-Mobile offer available in August 2026.

Orange has also added Tanzania to selected roaming solutions outside the EU, while Orange Flex Travel currently offers packages including 1 GB for 7 days for PLN 25, 5 GB for 7 days for PLN 65, and 10 GB for 15 days for PLN 110.

This shows an important change: roaming in Zanzibar does not always have to result in an extremely high bill if you activate the right package before travelling.

You should still never use mobile data without checking the terms first. Conditions depend on the operator, tariff, and current offer.

eSIM, local SIM, or roaming in Zanzibar – comparison

If your priority is convenient internet while travelling, eSIM is usually the most versatile option.

A local SIM may win on price and access to a local number, while roaming is convenient mainly when your Polish operator offers a good-value package for Tanzania.

How many GB of internet do you need in Zanzibar for 7–14 days?

The right data package depends mainly on how you use your phone.

If you only need internet for WhatsApp, maps, restaurant searches, reservations, and occasional Instagram use, your data consumption should remain relatively low.

As a rough guide:

• 3–5 GB – basic use for around one week,
• 5–10 GB – standard holiday use,
• 10–20 GB – social media, lots of photos and videos, frequent hotspot use,
• 20 GB+ or unlimited data – remote work, streaming, video calls, and intensive use.

Video, automatic cloud photo backups, app updates, and laptop hotspot use consume the most data.

A good idea is to download offline maps before departure and disable automatic system updates over mobile data.

Hotel internet in Zanzibar – is WiFi enough?

Many hotels, resorts, restaurants, and cafés offer WiFi. That does not mean the quality will always be sufficient.

In a large hotel, one network may be shared by many guests. As a result, speeds may drop noticeably in the evening when most people return to their rooms.

Hotel WiFi may be enough for:

• WhatsApp,
• browsing websites,
• email,
• simple bookings.

However, it is better not to rely on it as your only source of internet if you need stable access to maps, banking, transport apps, or work tools.

Public WiFi is also less secure than your own mobile connection. For online banking, company email, or work documents, using your own mobile data is generally safer.

Portable WiFi router in Zanzibar – when does it make sense?

A portable WiFi router can be an alternative to an eSIM or local SIM.

Its biggest advantage is the ability to connect several devices to one internet connection.

It is worth considering if you are travelling:

• with family,
• in a group,
• with a laptop and tablet,
• on business,
• with people whose phones do not support eSIM.

Instead of buying a separate data package for every phone, you can share one WiFi network.

The downside is that you need to carry and charge an additional device.

What should you check when choosing internet in Zanzibar?

The package price should not be the only criterion.

Checklist before buying an eSIM or data package

• Does the offer cover Tanzania and Zanzibar?
• Does my phone support eSIM?
• Which local networks does the eSIM use?
• How many GB are included?
• How long is the package valid?
• When does the validity period begin?
• Is hotspot/tethering allowed?
• Can I top up the package after using the included data?
• Does an “unlimited” plan have a daily full-speed data limit?
• Does the provider offer customer support?
• Is the plan data-only, or does it also include calls and SMS?
• Is manual APN configuration required?

It is worth checking these details before purchasing, not only after you arrive.

Is eSIM in Zanzibar worth it?

If you compare only the price per GB, a local SIM card may be cheaper.

However, once you include time, formalities, and convenience, the picture changes.

Imagine you are going to Zanzibar for 10 days. You need internet for maps, WhatsApp, Instagram, hotel contact, and occasional hotspot use.

In that scenario, buying an eSIM before departure means you do not need to:

• look for a SIM card shop after landing,
• register a local SIM,
• replace your physical SIM,
• configure a local package,
• rely entirely on hotel WiFi.

For many tourists, an eSIM for Zanzibar is worth it mainly because of convenience and cost control, not only the price per 1 GB.

If, however, you are staying for several weeks and use a lot of data, a local SIM may be more economical.

No internet in Zanzibar – what should you do?

If your eSIM or local SIM does not connect to the internet, it does not automatically mean the service is faulty.

First:

1. turn airplane mode on and off,
2. restart the phone,
3. check whether the eSIM profile is active,
4. make sure the correct SIM is selected for mobile data,
5. enable data roaming on the travel eSIM if required by the provider,
6. check the APN settings,
7. try manually selecting another supported network,
8. move to an area with better coverage.

If the problem continues, contact your eSIM provider’s customer support.

FAQ – internet and eSIM in Zanzibar

Does eSIM work in Zanzibar?

Yes, as long as the eSIM package covers Tanzania/Zanzibar and your phone supports eSIM technology. Before purchasing, check the list of supported countries and networks.

Does EU roaming work in Zanzibar?

No. Zanzibar is part of Tanzania and lies outside the EU/EEA, so Roam Like at Home does not apply. Some Polish operators do, however, offer special data packages for Tanzania.

Do you need to buy a SIM card at the airport?

No. You can buy a local SIM after arrival, but it is not necessary. If your phone supports eSIM, you can purchase and install a data package before travelling.

Do you need a passport to buy a local SIM card in Zanzibar?

Yes. Tanzania requires SIM card registration. Tourists must present a travel document, and the process may include biometric verification.

Will WhatsApp work with an eSIM in Zanzibar?

Yes. If the eSIM provides internet access, WhatsApp works normally. You do not need to change your WhatsApp number to the eSIM number. With a data-only eSIM, the app can continue using your existing account number.

Can you use hotspot with an eSIM?

It depends on the specific package. Many providers allow you to share internet with a laptop or tablet, but you should check the tethering rules before buying.

How many GB of internet do you need for one week in Zanzibar?

For most tourists, 5–10 GB for one week should be enough for comfortable use of maps, messaging apps, web browsing, and social media. Streaming and hotspot use can significantly increase data consumption.

Does eSIM work in every country?

No. Availability depends on the provider and the specific package. However, local, regional, and global eSIMs are available, so one profile can cover several or even many countries. This can be useful, for example, on a trip combining Zanzibar with mainland Tanzania or other countries in the region.

Summary – what is the best internet option in Zanzibar in 2026/2027?

There is no single perfect solution for everyone, but for a typical Zanzibar holiday, the choice can be simplified considerably.

eSIM is the best option for travellers who want to prepare internet access before departure and avoid looking for a local store.

A local SIM card can be more cost-effective for longer stays or very heavy data use, but it requires registration and some time after arrival.

Roaming is worth considering if your Polish operator offers a good package for Tanzania. Such packages are available in 2026, but you should always check the price and data allowance before departure.

Hotel WiFi is best treated as a supplement rather than your only source of internet.

If you want your internet in Zanzibar ready before you even board the plane, check the available eSIM packages for Tanzania/Zanzibar and choose a data allowance that matches the length of your trip. That way, once you arrive, you can focus on your holiday instead of looking for a SIM card.
