Staying Connected on the EBC Trek: SIM Cards, Coverage & Real Talk from Trekkers

One of the first questions that pops up when you’re planning your Everest Base Camp trek — “How do I stay connected up there?” And let’s be real, while most of us go to the mountains to disconnect, staying in touch with loved ones (and maybe uploading that epic Namche Bazaar photo) is still high on the list.

So, what’s the deal with mobile SIM cards in Nepal? Should you get one? Which one? Can you snag one before arrival, or should you buy at the airport? Let’s break it all down — with real traveler tips included.

SIM Card Showdown: NTC vs. Ncell

Nepal has two major SIM providers: Nepal Telecom (NTC) and Ncell. Both offer prepaid SIMs, internet packages, and local rates that make them way more budget-friendly than your international roaming plan.

But which one works better on the trail? Based on what a lot of trekkers have reported, NTC (also called Namaste SIM) is the clear winner for the EBC region.

✅ NTC Highlights:

• Better coverage, especially as high as Dingboche (4,410m)

• More consistent 3G/4G in remote areas

• Works in many villages where Ncell fails

• Available at Kathmandu airport — super easy to get on arrival

🚫 Ncell Pitfalls:

• Spotty service beyond Tengboche

• Doesn’t always work in tea houses (especially indoors)

• Often pushed by vendors in Thamel (higher commission for them)

Some trekkers found Ncell worked “okay” while walking, but dropped completely in lodges. Others went with NTC and got reliable internet and call signals all the way to Dingboche.

Pro Tip: If staying connected is crucial, some travelers recommend getting both SIMs — they’re cheap (~NPR 450 or ~$3) and having a backup doesn’t hurt.

Where to Buy: Airport or Online?

While you technically can arrange an eSIM or even order ahead online, most people grab their SIM cards right at the Kathmandu airport. Why?

• It’s fast and convenient

• Staff can help activate the SIM and fix issues immediately

• You’ll have a working number before you even leave the city

Some prefer to get their SIM in Thamel (the tourist hub in Kathmandu) where there are more options and English-speaking vendors — but unless you want to haggle or shop around, the airport is easy-peasy.

International Roaming vs. Local SIM

If you’re using AT&T, Verizon, or other international plans — here’s the lowdown:

• AT&T’s $10/day plan works occasionally but isn’t reliable in higher altitudes.

• Some hikers reported it worked around Namche but dropped off completely after that.

• Even with international plans, you’ll probably end up buying Wi-Fi at tea houses.

A few trekkers used Airalo (eSIM provider) for travel data and made calls via WhatsApp and Messenger. This is a solid choice if your phone supports eSIM and you don’t need a local number.

What Actually Works Above Namche?

Here’s how things typically play out:

Final Tips from Fellow Trekkers

• Hydrate & unplug: Many found it refreshing to not be constantly connected above Namche.

• Signal is outdoors: SIMs may work better outside tea houses — indoors can be tricky.

• Wi-Fi is king above 4,000m: Expect to pay around NPR 300–800 per night for Wi-Fi access.

• Don’t expect Netflix: Even with Wi-Fi, speeds can be turtle-slow. Keep expectations realistic.

• Keep both SIMs if you can: NTC for upper elevation, Ncell as a backup or for city use.

TL;DR

• NTC (Namaste SIM) is your best bet for the EBC trek.

• Buy it at Kathmandu airport for the easiest setup.

• Don’t count on international roaming to work reliably.

• Combine local SIM + Wi-Fi for the best connectivity.

• And maybe… let go of the signal and soak in the mountains. The Himalayas are the real connection.
