Good to Know
- Over 90% of Nepal's international internet traffic passes through India (Airtel ~70%, Tata ~20%), which has historically caused nationwide outages when payment disputes arise; this dependency is a structural reliability constraint.
- Ncell offers the fastest mobile data speeds and best urban 4G coverage in Kathmandu; NTC provides more reliable rural/remote coverage if you travel outside the city.
- Home broadband (fiber) is highly affordable (₹1,500–₹2,000/month) and stable in central Kathmandu, making it the best choice for remote workers; verify fiber availability at your exact address before moving.
- Physical SIM cards are extremely cheap (₹100) and easy to buy at the airport or city shops; e-SIM is convenient but still limited to official service centers and may not work everywhere nomads live.
- Mobile 4G speeds in Kathmandu reach ~10 Mbps real-world, sufficient for video calls and browsing but not high-bandwidth streaming.
- WiFi in cafes and hotels is common but unreliable and slow (5–20 Mbps); don't rely on it for critical work.
- Nepal Telecom (NTC) monopolizes landlines and fixed broadband in some areas; in central Kathmandu, multiple ISPs compete, giving you choice.
- Political protests and government directives have occasionally triggered internet shutdowns or throttling; these are rare but possible.

Connectivity Reliability Tier Rationale
Kathmandu has widespread fiber (FTTH) infrastructure, excellent mobile 4G coverage from multiple carriers, and reliable fixed broadband from competing ISPs; however, occasional outages linked to upstream Indian provider payment disputes and periodic political disruptions prevent a “Very high” rating.
Note
Most ISPs use Fiber-to-the-Home (FTTH) technology. Annual subscriptions typically offer better value than monthly. Fiber availability is concentrated in Kathmandu Valley and not guaranteed in all neighborhoods—verify coverage at your specific address before committing.
