Tanzania eSIM for Arusha, Moshi and island stays
Compare Tanzania eSIM plans for Kilimanjaro airport, an Arusha or Moshi stay, and a separately managed ferry and island visit.
Kilimanjaro International Airport is a starting point, not the final town: ground transfers can lead to Arusha or Moshi. Confirm the town, lodging and organiser before arrival. Dar es Salaam adds separate steps for city or airport arrival, ferry terminal, sailing booking and island accommodation. The ferry operator lists Zanzibar, Pemba and Tanga, but the route does not prove mobile service at sea or island inclusion in the selected eSIM. Save each booking and next pickup independently.
For this trip
Which eSIM suits a mainland-and-island Tanzania trip?
Choose a plan listing every intended territory and lasting from the first mainland transfer through the island stay. Select enough data for organiser messages, booking changes, maps, internet calls, photos and hotspot use. Treat Arusha and Moshi as different transfer destinations, and the Dar es Salaam terminal, sailing and island pickup as separate stages. The Horizon Africa package does not include Tanzania.
Horizon sells the plans presented here, so this page is not a neutral market comparison or ranking. Read the live product details before deciding.
Data amount

Full-trip validity

Explicit destination inclusion
Confirm Tanzania and the named island in the selected product, then check any later country separately; Horizon’s Africa package does not include Tanzania.

How eSIM works in United Republic of Tanzania
Add the eSIM over reliable Wi-Fi and keep instructions outside the phone. Leave it off until Tanzania, then select Horizon for data and enable roaming. The first successful connection to a supported network in the included destination starts the selected validity. Keep home-line roaming off unless you accept its charges. Before an outdoor day or ferry, store the organiser contact, ticket, meeting point and island address offline; do not rely on mobile reception or onboard Wi-Fi.
Install your eSIM
Scan the QR or auto-install in the app — no physical SIM.
Land & connect
Data activates on first connection at your destination.
Size it to your trip
Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.

- A short call home most days
In total, a 5 GB data allowance covers roughly 1,700 shared photos, 83 hours of social media and browsing, 15 hours of video calls, 63 hours of music streaming, or about 1000 hours of maps and navigation. Messaging apps barely use data.
Important cities in United Republic of Tanzania
Arusha · City guide
Arusha
Ground transfers from Kilimanjaro International Airport can lead to Arusha. Keep the confirmed vehicle or organiser contact with the lodging address; the airport name alone does not identify the final meeting place.
Arusha eSIM — set up before you fly →Moshi · City guide
Moshi
Moshi is a separate onward choice from the same airport. Save the lodging and organiser meeting point before departure, and keep essential instructions independent of mobile reception for any outdoor day.
Moshi eSIM — set up before you fly →Dar es Salaam / Zanzibar · City guide
Dar es Salaam / Zanzibar
A Dar es Salaam-to-Zanzibar journey has several records: city or airport arrival, ferry booking, terminal instructions and island accommodation. Use data to manage changes and coordinate the next pickup, but keep the ticket and final address offline.

Choose a Tanzania eSIM for mainland and island stages
Choose a data amount and validity for every confirmed stage, including organiser messages, booking management, maps, internet calls, photos and hotspot use. Confirm mainland Tanzania in the exact plan, then check Zanzibar or Pemba separately if either is on the itinerary; geography alone is not product coverage. Tanzania is outside Horizon's current six-destination Africa package, so that regional label does not include this trip. Any other country also needs its own explicit listing.

Frequently asked questions
Should my airport transfer go to Arusha or Moshi?
Follow the confirmed lodging and organiser booking. Both towns can be reached by ground transfer from Kilimanjaro International Airport, but they are different final addresses and meeting arrangements.
What should I save for the Zanzibar ferry?
Keep the sailing booking, terminal instructions, operator contact and island accommodation address offline. Use data for booking changes and the next pickup, without relying on reception at sea or onboard Wi-Fi.
Does my Tanzania package include Zanzibar or Pemba?
Check the selected product's exact destination and territory list. Do not infer island eligibility from the Tanzania name, the ferry route or political geography; verify Zanzibar or Pemba for that product before buying.
Will the eSIM work at sea or throughout an outdoor trip?
That is not guaranteed. A listed territory does not promise reception on water or at every outdoor location. Keep the ticket, return plan, organiser contact, meeting point and essential instructions offline.
How should I choose validity for mainland and island stages?
Cover the entire confirmed itinerary, including arrival, transfer days, ferry stage and island stay. The first successful supported-network connection in an included destination starts Horizon's selected validity period.
Can I keep my number and share a hotspot in Tanzania?
With a compatible dual-SIM device, the home SIM can remain installed; its provider may charge for active services. Horizon is data-only and includes no local number. Hotspot sharing is free on every Horizon plan, draws from the same allowance and is not throttled.
