eSIM for Tanzania

eSIM, roaming or a local SIM in Tanzania

Here is how the main options compare, so you can decide what fits your trip.

How much data to plan for

A Tanzanian trip often mixes days with no signal at all on safari with beach days on Zanzibar when you want to share everything. These rough figures can help you estimate:

• Maps and navigation: a few megabytes per hour of driving or walking.
• Messaging and email: light, but safari photos and videos add up quickly.
• Social media: moderate to heavy, especially with wildlife video.
• Video calls: typically several hundred megabytes per hour.
• Streaming video: heavy, often over a gigabyte per hour in high definition.

Before you travel

Installing an eSIM needs an internet connection, so do it at home on Wi-Fi. First check your phone supports eSIM and is carrier-unlocked.

Then follow the install guide for iPhone, Samsung or Pixel. Label the line "Travel", keep your home SIM for calls and texts, and set the Spidot line for mobile data.

• Install a day or two before departure, not at the gate.
• Keep the QR code email in a safe place.
• Download offline maps for Arusha, the safari parks and Zanzibar.
• Save your safari itinerary, park permits, flight tickets and your operator's contact details offline.
• Bring a power bank and a car charger; charging on safari may be limited to the vehicle or the lodge's generator hours.

Arriving in Tanzania

Tanzania has three main international gateways. Kilimanjaro International Airport, between Arusha and Moshi, is closest to the northern safari parks and the mountain. Julius Nyerere International Airport serves Dar es Salaam, and Abeid Amani Karume International Airport serves Zanzibar. Small planes link these with airstrips inside and near the national parks.

When you land, choose the Spidot line for mobile data and turn on data roaming for it, as explained in our data roaming guide. Allow a minute or two for the phone to connect; if needed, switch flight mode on and off.

Coverage in cities, on safari and on Zanzibar

In Dar es Salaam, Arusha, Moshi, Dodoma, Mwanza and Zanzibar's Stone Town, mobile data generally works, and main roads between towns usually have signal near settlements. Mobile data in Tanzania is provided via Airtel.

Tanzania is a large country with vast protected areas, and coverage is much less predictable away from towns:

• Serengeti and other parks: some lodges, camps and park gates have signal, but large areas of the parks have little or none.
• Ngorongoro Crater: the crater rim, where many lodges sit, can have signal; on the crater floor it is variable.
• Southern parks: Ruaha and Nyerere National Park are remote, and coverage is limited.
• Rural roads: long drives between Arusha and the parks pass through areas with gaps between towns.
• Zanzibar: Stone Town and the main beach areas are generally covered; quieter coastal stretches can be weaker.

Data on safari, ferries and road trips

How you move around Tanzania shapes how you use data.

Hotspot for laptops and travel companions

Personal hotspot lets you share your eSIM data with a laptop, tablet or a travel companion's phone. It uses whichever line is set for mobile data, so make sure that is the Spidot line. This is handy in lodges where Wi-Fi is limited to the main building, for families sharing one plan and for remote workers on Zanzibar.

Pause cloud sync, automatic updates and photo backups before connecting, and choose a larger or unlimited plan if several devices will share your data.

Staying safe on public Wi-Fi

Hotels, lodges, cafés and some restaurants offer Wi-Fi, though speed varies. Open networks are not always secure.

• Use your eSIM data for banking, payments and logins.
• Check the network name with staff before connecting.
• Turn off automatic connection to open networks.
• Keep your phone's software up to date before you travel.

Practical tips for Tanzania

Some local knowledge that makes a data connection more useful:

• Currency: Tanzania uses the shilling. US dollars are commonly used for safaris and some tourist services, and cards are accepted at larger hotels and lodges. Carry cash for tips, markets and small shops.
• Mobile money: many Tanzanians pay with mobile money linked to a local number. As a visitor, you will mostly use cash or cards.
• Photography: ask before photographing people, especially in Maasai villages and on Zanzibar. Some government buildings and installations should not be photographed.
• Zanzibar customs: Zanzibar is largely Muslim. Dress modestly in Stone Town and villages, especially during Ramadan.
• Dust, heat and charging: dust on safari and heat on the coast are hard on phones. A dust-proof case and a power bank help.
• Language: Swahili is the national language, and English is widely used in tourism. Learning a few greetings is appreciated.

Combining Tanzania with other countries

Tanzania is often combined with its neighbours. Popular combinations include the Maasai Mara in Kenya, gorilla trekking in Rwanda or Uganda, and onward travel to Malawi, Zambia or a beach stay in the Seychelles or Mauritius.

For trips through several countries, buy one eSIM per country, install them before you leave and switch the active data line when you cross each border. Near borders, such as between the Serengeti and the Maasai Mara, your phone may connect to a neighbouring network; check the network name if data stops working. For a trip in Tanzania only, a Tanzania plan keeps things simple.
