How Does SIM Card & Internet Work in Tanzania?
Last verified: 2025-06 · Africa & Oceania
1The Quick Answer
Vodacom Tanzania offers the best coverage including in most national parks; buy a SIM at the airport with your passport and expect patchy signal on Kilimanjaro upper slopes.
2What You Need to Know
Vodacom Tanzania is the market leader for data coverage and is the most reliable network for tourists visiting national parks, with reasonable signal in the Serengeti and Ngorongoro Crater. Airtel Tanzania and Tigo are alternatives with competitive data pricing but weaker rural coverage. SIM cards are available at Julius Nyerere International (Dar) and Kilimanjaro International airports, requiring your passport for registration. Airalo and other eSIM providers offer Tanzania data plans that work on arrival without needing a physical SIM. Coverage on Kilimanjaro deteriorates significantly above 3,000m and is unreliable above Horombo Hut.
3Practical Tips
Practical Tips
- 1Buy your Vodacom SIM at the airport arrivals hall immediately after clearing customs — the process takes five minutes and data packages are very affordable.
- 2Load a generous data bundle upfront (5GB or more) as topping up in national parks is impossible and lodge Wi-Fi is often slow or expensive.
- 3Zanzibar uses the same Tanzanian networks — your mainland SIM works seamlessly on the island without any changes.

Vodacom offers the best coverage; buy a SIM at the airport or any mall with your passport; 4G is good in cities but patchy in game reserves.
Spark has the best rural coverage; tourist SIM packages are available at airports, supermarkets, and convenience stores.
Buy a Dhiraagu or Ooredoo SIM in Malé or at the airport — resorts provide WiFi, but coverage thins out significantly on outer atolls.
