Northern Pakistan SIM & Coverage: Hunza, Skardu & the KKH

The north is why serious travellers come to Pakistan. The Karakoram Highway climbing through the mountains, the orchards of Hunza, the lakes and peaks around Skardu, this is some of the most spectacular country on earth. It is also where your phone quietly stops being useful, and understanding that before you go is the difference between a relaxed trip and a worrying one. Coverage up here does not work the way it does in the cities, and no amount of buying the right plan changes the geography.

So this is an honest guide to connectivity in Gilgit-Baltistan: the strange network that actually runs the region, what a travel eSIM realistically gets you, and exactly where the signal disappears.

The north runs on a network you have probably never heard of

Down in the cities, Pakistan has the four operators everyone knows: Jazz, Zong, Telenor, and Ufone. Up in the mountains there is a fifth, and in many places it is the only one that matters. SCOM, run by the Special Communications Organization, is a government network operated by the Pakistan Army's Signal Corps, and it exists specifically to serve Gilgit-Baltistan and Azad Kashmir, the regions no private operator was willing to wire up. It reaches into valleys, mountain passes, and border areas that the commercial networks never bothered with. It even installed the first mobile tower at K2 base camp, at over five thousand metres, where expeditions once depended entirely on satellite phones.

Why does this matter to you? Because your travel eSIM does not run on SCOM. Travel eSIMs connect through the national operators, in practice usually Zong or Jazz, and their coverage fades exactly where SCOM takes over. Knowing that shapes everything about how you plan.

What a travel eSIM actually gets you up here

Here is the reassuring part, and it is genuinely true rather than a sales line: the trip most people actually do in the north is well covered. If your itinerary is the classic one, the drive up the Karakoram Highway with stops in Gilgit, Karimabad in Hunza, and Skardu, a good travel eSIM keeps you online for the great majority of it. The key is which network it uses, and the honest answer is that the two big players are both solid here for different reasons. Zong tends to be the quickest in the northern towns, helped by a network-sharing partnership with SCOM, and it holds the Karakoram Highway corridor well. Jazz is the largest network in the country with the widest rural and highway reach, and plenty of travellers rate it just as highly in the north, especially for staying connected on the long stretches between towns. Either is a sound choice, so a plan that runs on Jazz or Zong, or better still one that can use both, will handle the towns, the guesthouses, and most of the main road perfectly well.

What it will not do is follow you into the deep valleys and up to the high passes. That is not a fault in the plan. It is simply where the commercial network ends and where, if anything reaches at all, it is SCOM. Set your expectations there and you will not be caught out.

Coverage, valley by valley

The honest, specific picture, which matters far more than a vague "coverage can be patchy":

• Islamabad (your starting point): excellent 4G and 5G on every network. Sort everything here.
• The Karakoram Highway: good in the towns, drops away in the deep gorges between them. Expect stretches of nothing.
• Gilgit city: strong 4G on Zong, Jazz, and SCOM.
• Karimabad (central Hunza): genuinely good, with solid Zong and SCOM 4G.
• Upper Hunza (Passu, Gulmit): SCOM is the reliable one here; Zong is moderate at best.
• Sost (near the border): basic service, often only 3G.
• Skardu city: good 4G on Zong, Jazz, and SCOM.
• Khunjerab Pass (4,693m, the China border): no mobile coverage at all.
• Deosai Plateau: extremely limited, effectively offline.
• Fairy Meadows and Nanga Parbat base camp: very limited SCOM, nothing else.

If you are trekking seriously, plan for no signal at all

This is worth saying plainly, because it is a safety point rather than a connectivity nicety. On the big treks and the remote plateaus, Deosai, Fairy Meadows, the routes toward Concordia and K2, you should assume you will have no phone signal for days, on any network. If you are heading into that kind of terrain, a satellite messenger or phone is the sensible tool, not a SIM, and the basic rule of mountain travel applies: tell someone reliable your route and your expected return time before you set off. No eSIM, and no SCOM SIM either, changes the fact that these places are genuinely off-grid.

How to actually stay connected in the north

Put all of that together and a simple plan covers almost everyone:

Get a travel eSIM that runs on Jazz or Zong and install it before you fly. Between them these two give you the best national coverage in the north, with none of the registration hassle of a local SIM, and you land ready. If you are unsure why buying ahead matters and how Pakistan's phone rules work, our Pakistan eSIM guide covers the full picture.

Download offline maps for the entire northern region before you leave Islamabad, while you still have fast data. Google Maps offline areas plus a backup like Maps.me will get you through every dead zone on the road. Keep WhatsApp ready too, because it is how the guides, drivers, and guesthouses all coordinate, and it works fine wherever you have any signal.

Carry a power bank, since cold mountain mornings drain a battery fast, and a dead phone is worse than no signal. And if you are spending serious time deep in the valleys, a local SCOM SIM is the one thing that reaches where nothing else does, though as a foreigner you will need your passport and visa and a visit to an official SCOM franchise in Gilgit or Skardu to get one. For most travellers doing the towns and the highway, that is more effort than it is worth, and the Zong eSIM plus offline maps is the comfortable choice.

Compare Pakistan eSIM plans, look for one that runs on Jazz or Zong for the north, and read the main Pakistan guide before you travel.
