Good to know
Good to Know
- Tigo (now rebranded as Yas) is the clear winner for Zanzibar with fastest speeds (65+ Mbps) and most reliable coverage; buy it in Stone Town at local prices rather than airport tourist prices
- Interior of Zanzibar island and smaller satellite islands have spotty coverage for all carriers—expect dead zones even when using the best network
- International e-SIMs operate on weaker networks (mainly Airtel/Vodacom) in Zanzibar and cost more per GB than buying a local SIM; e-SIMs are best for arrival convenience only, not long stays
- Home broadband (fixed line) is underdeveloped in Zanzibar with unreliable copper networks; mobile data is more practical for digital nomads
- Hotel WiFi is often advertised but frequently slow or non-functional—budget for mobile data even if accommodation claims WiFi is included
- SIM registration is mandatory and takes time (20-30 min); budget this into your arrival day. You will need your passport
- Data is very affordable when bought locally (TSH 15,000 ≈ $5.70 for 1.5 GB); avoid airport and tourist-facing vendors who mark up prices significantly

Connectivity Reliability Tier Rationale
Mobile networks like Tigo/Yas offer decent coverage in tourist areas and Zanzibar City, but fixed broadband is limited/unreliable, interior coverage is spotty, and e-SIM options don't align well with the best local network, necessitating backup SIM strategies.
SIM Card Costs
- Physical SIM Card
- TZS 1,000
Cost of SIM card itself (usually includes TSH 500 credit). Price relatively standard across providers
Mobile Coverage And Speeds
- Reliability
- Decent in urban/tourist zones; interior coverage spotty for all carriers; island has coverage gaps even in Zanzibar City
- 5g Availability
- Limited; primarily in Zanzibar City area on Tigo/Yas network
- 4g LTE Availability
- Widely available in Zanzibar City/Stone Town and main tourist areas; coverage more spotty in interior and remote areas
Speeds Mbps
- Airtel
- Competitive 4G speeds; second-best option
- Vodacom
- Good on mainland; weaker/fragmented in Zanzibar
- Tigo Yas
- 65.76 Mbps average (best performer in Zanzibar)
Practical Tips
- Backup Strategy
- Consider dual SIM setup (two different providers) due to coverage gaps island-wide
- Registration
- All local SIM cards require passport registration (photo, fingerprint scan, ID copy); this is mandatory and unavoidable
- Wi-Fi Reliability
- Hotel/café WiFi often slow or unreliable; do not rely on it as primary connectivity
- Best Practice SIM Card Purchase
- Buy local prepaid SIM in Stone Town (Zanzibar City) rather than airport—local prices much lower, better selection. Registration takes 20-30 minutes
