Best eSIM for Zanzibar (2026 Guide)
Zanzibar — white sand beaches, Stone Town's spice alleys, and some of East Africa's best diving — also has surprisingly good mobile coverage. Here's what eSIM to get and where signal actually works.
Quick Answer
What is the best eSIM for Zanzibar in 2026?
Zanzibar is in Tanzania, so you need a Tanzania eSIM. Airalo's Tanzania plan on Vodacom TZ (from $8) is the top pick — Vodacom has strong 4G in Stone Town, Nungwi, and Kendwa. If you're visiting Kenya before Zanzibar, buy both plans in the Airalo app and switch at the airport.
Kenya eSIMs do not work in Zanzibar — you need a Tanzania-specific plan.
Important: Zanzibar is Tanzania
Zanzibar Island (and Pemba) is an autonomous part of Tanzania. You need a Tanzania eSIM — not a Kenya eSIM. Most Kenya eSIMs are Kenya-only and won't connect in Tanzania.

Zanzibar eSIM Tips
- 1Buy your Tanzania eSIM before departure — it activates the moment you land at Zanzibar Airport (ZNZ).
- 2If coming from Nairobi or Mombasa by flight, activate your Tanzania eSIM just before boarding or immediately after landing.
- 3Vodacom TZ gives you the best beach resort and Stone Town coverage. Airtel TZ is a decent backup for urban use.
- 4Download offline Google Maps of the island — you'll want maps for spice tour routes and beach exploration.
- 54G speeds in Stone Town and Nungwi typically reach 15–25 Mbps — enough for WhatsApp, maps, and Instagram easily.
- 6Pemba Island has limited coverage. If you're diving there, download everything offline in Stone Town first.
Frequently Asked Questions
What is the best eSIM for Zanzibar?
Zanzibar is part of Tanzania, so you need a Tanzania eSIM. Airalo's Tanzania plan (from $8 on Vodacom TZ) is the most popular and well-reviewed option. Holafly also offers Tanzania plans. Stone Town, Nungwi, and Kendwa all have good 4G from Vodacom.
Does a Kenya eSIM work in Zanzibar?
No — Zanzibar is part of Tanzania, and Kenya eSIMs are country-specific. You need a Tanzania plan. Airalo, eSIM2Fly, and Maya Mobile all offer Tanzania coverage. If you're coming from Kenya, activate a new Tanzania plan before or after landing at Zanzibar Airport (ZNZ).
Is there good internet on Zanzibar beaches?
Yes, surprisingly well. Nungwi, Kendwa, and Matemwe on the north coast have consistent 4G from Vodacom TZ. The east coast (Paje, Jambiani) has good but slightly less consistent coverage. Pemba Island is more limited.
What network should I use for Zanzibar?
Vodacom Tanzania is the strongest network on Zanzibar Island, particularly in Stone Town and the northern beach resorts. Airtel Tanzania is also present and works well in urban areas. For eSIM, choose a Vodacom-routed plan for best results.
Can I use eSIM for both Zanzibar and Nairobi on one trip?
You need two separate eSIM plans — one for Kenya (Safaricom-based) and one for Tanzania/Zanzibar (Vodacom TZ-based). Airalo makes this easiest with both plans managed in one app.
