Most travellers need a Tanzania tourist visa, and since 2025 the reliable way to get one is the official online e-visa applied for before you fly, not at the airport. Sort it early, because the same trip planning is when you should line up mobile data. Tanzania is an East African country covering the mainland safari circuits and the Zanzibar archipelago, and both sit under one visa.
This guide walks through the visa itself, the passport and health rules that decide whether you board the plane, and how to keep your phone working from Kilimanjaro arrivals to a game drive in the Serengeti. The rules shift from year to year, so I have leaned on official immigration guidance and checked the current picture. Read it once now and again a week before departure.
Skip the airport SIM queue and land connected: get an Africa-ready eSIM from Airalo before you fly.
The Tanzania tourist visa and how to apply for your trip
Nearly all visitors from Europe, North America, Australia and most of Asia need a visa to enter Tanzania for tourism. The standard tourist permit is the Ordinary Visa, a single-entry document valid for a stay of up to 90 days. The exception worth flagging early: United States passport holders are directed to the Multiple Entry Visa, valid for twelve months, even for a straightforward holiday.
You apply through Tanzania’s official e-visa portal, run by the Immigration Services Department. I am not printing a web address here because unofficial lookalike sites are common and the safest habit is to reach the portal through the government’s own domain rather than a link in an advert. You fill in the online form, upload your documents, pay by card, and wait for the approval to land in your inbox.
The process is straightforward but not instant. Official guidance says applications are processed within about ten days, and in the busy months from July to September and again around December and January the queue can stretch. Apply at least three weeks before you travel. Print the approval letter and carry it with you, because the airline check-in desk and the immigration officer on arrival will both want to see it.
Visa on arrival, e-visa, and which route to trust
A common point of confusion is whether you can still just turn up and buy a visa at the airport. The honest answer is that visa on arrival still physically exists at Kilimanjaro International Airport, Julius Nyerere in Dar es Salaam, and the main land borders, but Tanzanian immigration now actively advises travellers to secure the e-visa in advance. There is no guarantee of entry if you gamble on the arrival counter, and the queue after a long-haul flight can run 30 to 60 minutes.
The practical takeaway is simple. Treat the e-visa as the default and the arrival option as a fallback you would rather not use. Booking your Tanzania safari around a pre-approved visa removes a real risk from the start of the trip. If your itinerary is fixed and your flights are booked, there is no upside to leaving the visa to chance at the desk.
Citizens of fellow East African Community states, including Kenya, Uganda, Rwanda and Burundi, generally enter without a tourist visa for stays up to 90 days under regional agreements. Rules by nationality do change, so if you hold one of these passports, confirm your current status before you assume you are exempt.
Passport validity, entry rules and the Zanzibar insurance step
Your passport must be valid for at least six months beyond your arrival date and hold at least one blank page for the entry stamp. Two blank pages is the safer margin if you are also transiting another country. A passport that expires four months after your trip will get you turned away at check-in, so check the expiry date the moment you start planning.
Immigration can ask to see a return or onward ticket and evidence that you can fund your stay. These checks are not applied to everyone, but they are within the officer’s rights, so have your flight confirmation reachable on your phone. One e-visa covers both mainland Tanzania and Zanzibar, so island-bound travellers do not need a separate Zanzibar visa.
Two health and cover points matter. If you are arriving from or transiting a country where yellow fever is endemic, you must show a valid yellow fever vaccination certificate, and immigration wants the original card, not a photocopy. Separately, Zanzibar now requires all arriving tourists to hold a specific inbound travel insurance policy bought through the official island tourism system, and this is checked at Zanzibar’s airport regardless of any other insurance you already carry.
Single entry, valid for a stay of up to 90 days. The standard tourist permit for most nationalities visiting for a holiday or safari. Covers both the mainland and Zanzibar under one approval.
Valid for twelve months with multiple entries. Required for United States passport holders even for tourism, and useful for anyone crossing in and out of Tanzania during a longer regional trip.
Still issued at major airports and borders but no longer encouraged by immigration. Best treated as a backup, not a plan, given the queue and the lack of any guarantee of entry.
eSIM and mobile data options for the Tanzania traveller
An eSIM is a digital SIM built into most recent phones that lets you buy and load a data plan before you ever land. For a short safari trip it is usually the least painful way to stay online: you install it at home, and it switches on when you connect to a Tanzanian network on arrival. No airport counter, no fumbling with a tiny physical card, no giving up your own number.
The two names travellers reach for most are Airalo and Holafly. Airalo runs on local networks including Vodacom’s infrastructure and sells tiered data packs from around 1 GB up to larger 30-day bundles, which suits anyone who mostly needs maps, messaging and the odd upload. Holafly leans towards unlimited-data plans at a higher price, which makes sense if you plan to tether a laptop or make regular video calls. Other providers such as Saily and GigSky cover Tanzania too, so it is worth comparing before you buy.
Coverage on an eSIM is only as good as the local network behind it, and in Tanzania that means strong 4G in Dar es Salaam, Arusha and Stone Town, and thinner signal once you are deep in a national park. That is a network reality, not a fault of the eSIM, and a physical local SIM would behave the same way in the same spot.
Setting up your eSIM before you fly
The setup is quick if you do it while you still have solid home WiFi. First, confirm your phone is eSIM compatible and carrier-unlocked. Most iPhones from the XS onward and recent Google Pixel and Samsung Galaxy models support eSIM, but a phone locked to your home carrier will refuse a foreign profile.
Buy the plan in the provider’s app or website and you receive a QR code or an activation link. On an iPhone you add it under Settings, Cellular, Add eSIM, then scan the code; on Android it sits under Settings, Network, add an eSIM and scan. Install it before departure but leave your home line as the default for calls, and only switch data over to the travel plan once you land. Most plans give you a window of several weeks between purchase and first use, so installing early carries no penalty.
Check phone compatibility, unlock status, and buy your data plan. Install the eSIM profile over your home WiFi so any download problem is solved on your own network, not at a foreign airport.
Turn on the travel eSIM for data and let it register with a local network. Keep your home SIM active for two-factor codes and calls if you want to hold onto your usual number.
Save offline maps of your route and your visa approval letter to your phone before you fly, so a dead-zone stretch on the road does not leave you stranded without navigation or documents.
Buying a local SIM card in Tanzania
If your phone does not take an eSIM, or you simply want the cheapest per-gigabyte rate, a local SIM card is the alternative. Tanzania’s main networks are Yas, Vodacom, Airtel and Halotel. For the classic northern safari circuit and Zanzibar, Yas and Vodacom tend to give the broadest reach, and Yas in particular has a good reputation across the Serengeti area.
Registration is mandatory and takes a few minutes. You must show your passport, and your fingerprints are taken when the SIM is activated, so buy from an official network shop or an airport counter rather than a street seller who cannot register you properly. Kilimanjaro, Dar es Salaam and Zanzibar airports all have SIM stands, though airport pricing tends to run higher than a network store in town.
Local networks sell short tourist data bundles that are genuinely cheap. The trade-off against an eSIM is the queue, the registration step, and swapping out your own SIM. For a one-week trip many travellers find the eSIM’s convenience worth the small premium; for a longer stay the local SIM’s lower cost starts to win.
Staying connected on safari and in the parks
Set your expectations honestly for the wild parts of the trip. Mobile coverage in the Serengeti is patchy: you will usually find signal near the main gates, along the busier roads and close to the larger camps, but it drops away on the open plains and during a game drive. The Ngorongoro Crater follows the same pattern, with workable coverage around the rim where most lodges sit and weak, unreliable signal down inside the crater floor.
Most lodges and permanent camps offer WiFi, typically in the communal areas rather than the tents. Speeds vary a lot. Places running Starlink satellite internet feel close to normal, while camps relying on a cellular hotspot are fine for email and WhatsApp but will struggle with video calls or large uploads. Treat the network as good enough to reassure people at home, not as a mobile office.
Dar es Salaam, Arusha, Moshi and Stone Town have solid 4G on the main networks. Do your uploads, bookings and video calls here, where both eSIMs and local SIMs perform well.
Expect usable signal near Serengeti gates, main tracks and larger lodges. This is where you catch up on messages between drives rather than mid-safari.
Open plains and the Ngorongoro Crater floor are effectively off-grid. Download maps in advance and enjoy the disconnection; a signal here is a bonus, not a given.
Your Tanzania pre-trip visa and connectivity checklist
Bring the whole picture together a week out. Confirm your passport has six months of validity and a blank page. Apply for the e-visa through the official portal and print the approval. If you are heading to Zanzibar, buy the mandatory inbound travel insurance through the island’s official system and save the receipt with its QR code. If you are arriving from a yellow fever zone, pack the original vaccination card.
On the connectivity side, decide between an eSIM and a local SIM before you fly. If you go eSIM, install the profile at home and leave activation for arrival. Save offline maps, your visa letter and your lodge details to your phone so a dead zone never leaves you without your paperwork. Do these few things and both the border and your data will be sorted before wheels-up, leaving you free to concentrate on the safari itself.
How much does a Tanzania tourist visa cost?
The single-entry Ordinary Visa for most nationalities carries a government fee of 50 US dollars and allows a stay of up to 90 days. United States passport holders pay 100 US dollars for the Multiple Entry Visa valid for twelve months. Those are the official government fees, paid by card on the e-visa portal. Third-party agents add service charges of roughly 20 to 100 dollars on top for handling the same application, which is why applying yourself on the official portal is cheaper.
Can I still get a visa on arrival at Kilimanjaro Airport?
Visa on arrival is still physically issued at Kilimanjaro, Dar es Salaam and the main land borders, but immigration now advises applying for the e-visa in advance and gives no guarantee of entry to those who wait for the arrival counter. Expect a wait of roughly 30 to 60 minutes if you use it. Treat it as a backup rather than your main plan, and apply online at least three weeks before you travel.
How much does an eSIM or local SIM for Tanzania cost?
Airalo data packs for Tanzania start at a few dollars for the smallest allowance, with a 5 GB plan landing around 15 to 16 US dollars. Holafly’s unlimited-data plans cost more, scaling with the number of days. A local SIM is cheaper per gigabyte: Vodacom and Halotel sell bundles of several gigabytes for the equivalent of roughly 4 to 12 US dollars for a week or a month. The eSIM costs a little more but saves you the airport queue and the registration step.
Do I need mandatory travel insurance for Zanzibar?
Yes. Since October 2024, every tourist arriving in the Zanzibar archipelago must hold a specific inbound travel insurance policy bought through the official island tourism system. It costs 44 US dollars per adult for cover of up to three months, with a reduced rate for children aged 3 to 17 and free entry for under-threes. This is required even if you already have comprehensive travel insurance from home, and it is checked on arrival at the Zanzibar airport.
How reliable is mobile signal and WiFi on a Tanzania safari?
Signal is strong in cities and towns and around park gates and larger camps, but patchy on the open Serengeti plains and weak on the Ngorongoro Crater floor. Most lodges offer WiFi in communal areas, with camps running Starlink far faster than those relying on a cellular hotspot. It is generally enough for email and messaging but not for reliable video calls, so plan to catch up between game drives rather than during them.
What passport validity does Tanzania require?
Your passport must be valid for at least six months beyond your arrival date and have at least one blank page for the entry stamp, with two blank pages the safer margin. A passport nearing expiry can get you refused at check-in, so verify the date early. Immigration may also ask to see a return or onward ticket and proof that you can fund your stay, so keep your flight confirmation reachable.
