NTC has intermittent signal up to Namche Bazaar at 3,440 meters and patchy coverage in Tengboche. From Lobuche upward you will have no service on any carrier. Download offline maps and any trekking apps in Kathmandu or Lukla before starting the climb.

You will get LTE in Besisahar and Chame, patchy 3G in Manang on good days, then nothing above Thorong La. NTC occasionally reaches Manang but do not rely on it. Download your route maps and weather forecasts in Pokhara before the trek.

The main highway through Chitwan has LTE on both Ncell and NTC. Inside the park — Sauraha, the jungle lodges, the canoe routes — you drop to edge-of-network or lose signal entirely. Download any safari guides or bird checklists before entering.

Yes. NTC has slightly better coverage than Ncell in Lumbini and the surrounding Terai plains. You will hold LTE near the Maya Devi Temple and the main monastery zone. Expect 10-20 Mbps, enough for live maps and messaging.

You will only have signal for the first three to four days up to Namche, then nothing. Budget one to two gigabytes for that window — enough for daily WhatsApp check-ins, route confirmations and weather updates. The rest of the trek is offline.

Yes. WhatsApp voice and video calls work over LTE in Kathmandu, Pokhara and the main highway corridors. Call quality drops in hill towns and trekking routes where you fall back to 3G. Expect no service above 3,500 meters on any trail.

Google Maps or Apple Maps will consume around 100-150 megabytes per day if you leave navigation running for rideshare pickups and walking routes. Kathmandu traffic is dense, so the app recalculates frequently. Offline maps cut that to near zero.

Ncell is slightly faster in Thamel, Patan and the tourist zones, with typical LTE speeds around 15-25 Mbps. NTC is comparable in the city center and stronger in the northern valley and rural outskirts. The eSIM hands off automatically, so you get whichever is stronger at your location.

NTC has marginally better reach on high-altitude routes — it is the carrier that occasionally works in Namche Bazaar and Manang. Ncell thins out faster above 3,000 meters. Neither carrier provides reliable service above 3,500 meters on Everest Base Camp or Annapurna Circuit.

Yes. Pathao needs live data to match you with a driver, track the route and process payment through eSewa or Khalti. Both mobile wallets require an active data connection to confirm transactions, so keep your eSIM on during the ride.

Yes. inDrive operates the same way as Pathao — live data for driver matching, route tracking and wallet payments. If you pay cash the app still needs data to negotiate the fare and confirm pickup location.

Yes. eSewa is Nepal's dominant mobile wallet and requires live data to authorize payments, check balances and scan QR codes at shops. It integrates with Pathao, inDrive and most Kathmandu restaurants, so your eSIM keeps it functional on the move.

An eSIM installs in thirty seconds via QR code and you are online before leaving the arrivals hall. A physical SIM requires a passport photo, a deposit and a queue at the Ncell or NTC counter. Data allowances and coverage are identical; the eSIM just saves you twenty minutes and the deposit hassle.

Roaming often throttles after the first gigabyte and blocks hotspot, so you cannot share data with a trekking partner or tether a laptop at your Pokhara guesthouse. An eSIM gives you local-network pricing with no throttle and hotspot enabled. For treks the difference is small since you lose signal above Namche anyway, but in Kathmandu and Pokhara the eSIM is faster and cheaper.

Yes. Domestic flights to Tenzing-Hillary Airport in Lukla cancel frequently for weather. The Yeti Air and Tara Air apps let you check status and rebook in real time, but only with live data. Keep your eSIM active in Kathmandu so you can react without going back to the airline desk.
