eSIM for Tanzania — Serengeti, Zanzibar & Kilimanjaro

Traveling to Tanzania is an incredible experience, but arriving without data can ruin the first moments: no Google Maps to get out of the airport, no way to find your hotel, no way to contact whoever is waiting for you. The solution is simple and has been the standard among experienced travelers for years: an eSIM for Tanzania.

In this guide, we tell you everything you need to know before traveling to Tanzania: what coverage you can expect in Dar es Salaam, Zanzibar, and the Serengeti, how many GB you really need, how to activate the eSIM, and the best connectivity tips from those who have already traveled there.

Spoiler: with PuraSim, you have local data from the moment the plane lands, without contracts, without a physical SIM, and without bill surprises.

Why do you need an eSIM to travel to Tanzania?

International roaming from European and Latin American operators can cost you between 10 and 30 euros or dollars per day in Tanzania. A local eSIM gives you data at local prices, without absurd daily limits and with 4G or 5G speeds where the network allows.

The difference between going with roaming and with a PuraSim eSIM is brutal:

• Traditional roaming: fixed daily rate even if you barely use data, speed often limited to 3G, surprise bills upon return.
• PuraSim eSIM for Tanzania: you only pay for what you contract, full local data at maximum available speed, activation in 5 minutes from anywhere.

Furthermore, with an eSIM, you can keep your original phone number active to receive calls and SMS, as the eSIM operates in a separate virtual slot. You don't have to choose between local connectivity and your usual number.

For Tanzania, where there's no signal on Kilimanjaro's summit; Zanzibar has acceptable coverage in Stone Town, stable data is especially important. Coverage in Dar es Salaam, Zanzibar, and the Serengeti is generally good, but there are areas where you'd be in the dark without a well-configured local eSIM.

Data coverage in Tanzania: what to expect

Coverage in Tanzania varies considerably depending on the area. In major urban and tourist areas (Dar es Salaam, Zanzibar, and the Serengeti), you will find 4G and in some cases 5G networks. The experience is comparable to what you would have at home.

However, as with any destination, there are areas where the signal is more limited:

• Main cities: stable 4G/5G, perfect for streaming, browsing, and video calls.
• Rural and nature areas: coverage may drop to 3G or even lose signal in remote spots.
• Transport: trains, ferries, and intercity buses have variable coverage; generally good in cities.

Key tip: There is no signal on Kilimanjaro's summit; Zanzibar has acceptable coverage in Stone Town

To maximize coverage in Tanzania, PuraSim uses the local networks with the best available infrastructure through local roaming agreements. This means that your eSIM automatically connects to the network with the best signal at all times.

How many GB do you need for a trip to Tanzania?

This is the million-dollar question. The short answer: 5-7 GB for 10 days. The long answer depends on how you use your mobile during the trip.

Here's a guide to actual consumption by daily usage type:

• Basic use (maps, messages, occasional queries): 300-500 MB/day
• Moderate use (social media, photos, continuous browsing): 800 MB-1.5 GB/day
• Intensive use (remote work, streaming, video calls): 2-4 GB/day

For a trip to Tanzania lasting 10 days, our recommendation is to contract 5-7 GB for 10 days. This is enough for most travelers with normal use: Google Maps running constantly, Instagram, WhatsApp, and some occasional searches.

If you're going to work remotely or plan to make frequent video calls, upgrade to the next plan. PuraSim plans allow you to top up data if you run out, so it's not a problem if you fall short: you won't suddenly lose coverage.

How to activate your eSIM for Tanzania step-by-step

Activating a PuraSim eSIM is as simple as scanning a QR code. There's no need to go to a store, no need to wait for any shipment. The entire process takes less than 5 minutes:

1. Purchase your plan on purasim.com for Tanzania. You will receive an email with the QR code.
2. Install the eSIM: go to Settings → Mobile Data → Add Data Plan (on iPhone) or Settings → Connections → SIM Manager (on Android).
3. Scan the QR code or manually enter the activation data.
4. Configure mobile data: make sure to select the PuraSim eSIM as the default data line.
5. Activate data roaming in the PuraSim eSIM settings (necessary for it to work on local networks).

You can install the eSIM before leaving home and configure it to activate automatically when you arrive in Tanzania, or activate it manually when you land.

Important: verify that your phone is eSIM compatible before purchasing. Most iPhones from XS, Samsung Galaxy from S20, and Google Pixel from 3 are compatible. See the full list on purasim.com.

Local connectivity tips for Tanzania

Beyond getting the right eSIM, there are some tricks that make a difference to stay connected throughout your trip to Tanzania:

• Download offline maps before you leave. Google Maps and Maps.me allow you to download maps of all of Tanzania or specific cities. This way you can navigate without using data when you are in areas with a weak signal.
• Use airplane mode strategically. On long flights, trains, or ferries, activating airplane mode saves battery and data. Connect to available WiFi if there is any.
• WhatsApp and Telegram over data. Calls through these apps consume much less than an international call. Configure them for high-quality calls only when you are on WiFi.
• Share connection carefully. Hotspot consumes data quickly, especially if other devices are connected (laptop, tablet). Use it only when necessary.

And the most important tip: There's no signal on Kilimanjaro's summit; Zanzibar has acceptable coverage in Stone Town

With these tricks and a good PuraSim data plan, your trip to Tanzania will have the connectivity you need without unnecessary expenses.
