If you're heading to Pakistan, the fastest way online is an eSIM (a digital SIM profile you install without a physical card) rather than a SIM-shop queue after you land. co:sim's Pakistan eSIM is data-only, runs on Jazz's 4G network (independently ranked the country's fastest), and the QR code arrives by email within seconds of checkout — install it on Wi-Fi at home, then just switch it on when you land. The plan that fits depends on where your trip goes: a daily-refreshing allowance covers a week around Lahore, Karachi, and Islamabad comfortably, while a longer trip into the northern mountains needs a bigger data budget and a realistic read on where signal actually reaches. This guide compares Pakistan's live eSIM plans, breaks down which network covers what, and walks through installing before you land.
Four things decide which plan is worth buying:
A data-only eSIM carries mobile data but not a phone number — no calls or SMS through the plan itself, though messaging apps like WhatsApp work fine over data. If you need a Pakistani number for banking OTPs or a local contact, you'll still need a separate local SIM for that specific purpose.
Pakistan's live eSIM catalog runs from single-day passes up to a full month, all data-only and reloadable in most tiers. Rather than list prices here (check the plan page, since they change), here's how the shapes compare:
| Option | What you get | Best for |
|---|---|---|
| co:sim Pakistan eSIM: daily plans (500MB–10GB/day, 1 day) | A data allowance that refreshes each day on Jazz's 4G network; renew day by day for as long as you're there | Short trips, or travelers who'd rather pay per day than commit upfront |
| co:sim Pakistan eSIM: fixed bundles (1GB–20GB, 7–30 days) | One data pool for the whole trip; most tiers support a top-up if you run low, so you're not stuck reinstalling mid-trip | Week-long to month-long stays, remote work, heavier map/video use |
| Physical Jazz/Zong/Telenor/Ufone SIM | Requires your original passport and an in-person verification step at an authorised operator store before it activates | Long stays that need an actual Pakistani phone number |
| Home carrier's roaming day-pass | No setup at all, but day-pass roaming is commonly the priciest per-GB option carriers sell | Only if you genuinely need zero setup and don't mind paying for it |
That local-SIM row isn't hypothetical friction. Foreign visitors buying a physical Pakistani SIM need their original passport and must go through the operator's own verification process before the SIM activates, and guidance for tourists recommends buying only from authorised operator outlets rather than street vendors (Incredible Pakistan's SIM guide for tourists). It's exactly the counter visit an eSIM lets you skip. co:sim's own Pakistan plan page shows each tier's exact data type, validity, network, and top-up support before you buy, so there's no guessing which shape you're getting.
Pakistan's four mobile operators are not equal, and two independent 2026 measurements agree on the ranking. Ookla's Speedtest Connectivity Report for the second half of 2025 scored Jazz highest nationally, with a Connectivity Score of 59.83 and a median download speed of 24.13 Mbps, ahead of Zong in second, Ufone third, and Telenor last (Ookla via ProPakistani).
Pakistan's telecom regulator reached a similar conclusion in its own Q1 2026 Quality of Service survey across 18 cities: Jazz led overall KPI compliance at 95%, with Zong at 93%, Ufone at 89%, and Telenor at 78%, though Zong actually edged ahead on coverage and upload speed specifically (PTA QoS survey via ProPakistani). co:sim's Pakistan eSIM runs on Jazz, which puts it on the network both measurements rank fastest for the cities and highway corridors most travelers actually spend their trip in.
Pakistan's networks are also mid-upgrade. Jazz and Zong both switched on commercial 5G in Islamabad and other major cities in March 2026, with Ufone following shortly after (ProPakistani). co:sim's Pakistan eSIM currently runs on Jazz's 4G tier rather than 5G, which still carries the bulk of everyday mobile traffic in the country and is plenty for maps, messaging, and video streaming; 5G on travel eSIMs is one to watch for on future trips as handset and roaming support catches up.
That ranking flips once you leave the Punjab and Sindh cities for the north. In Gilgit-Baltistan (Hunza, Skardu, and the Karakoram Highway corridor), Jazz's signal is reported strong in the main bazaars but thins out fast in the side valleys, while Zong is the more consistently recommended operator for the highway itself, and the regional carrier SCOM covers stretches neither national network reaches well. Even the strongest local options report no coverage at all at Khunjerab Pass and in Deosai National Park (Heritage Hike's northern Pakistan connectivity guide).
That's not a co:sim-specific limitation: no single eSIM or physical SIM covers those gaps, foreign or local. Download offline maps before you leave the last town with signal, and don't count on data reaching you on a high pass or deep in Deosai.
For the well-trodden circuit most first-time visitors actually follow (Islamabad, Lahore, Karachi, and the main towns along the Karakoram Highway), a Jazz-based eSIM like co:sim's covers the trip without a second SIM. It's the deeper trekking routes and high-altitude passes where a supplementary local option earns its keep.
co:sim TeamSettings → Cellular (or Mobile Data) → Add eSIM, and scan the QR code from a second device or the confirmation email.For most trips, a data-only eSIM on Jazz's network is the strongest single choice. Independent 2026 testing from both Ookla and Pakistan's telecom regulator ranks Jazz as the country's fastest and most compliant network overall. co:sim's Pakistan eSIM runs on Jazz, ships as a QR code by email within seconds of checkout, and comes in both daily-refreshing and fixed-data-bundle plans so you can match the shape to your trip length. It covers Islamabad, Lahore, Karachi, and the main Karakoram Highway towns well. The one exception is deep trekking routes and high mountain passes in Gilgit-Baltistan, where every network, local or foreign, gets patchy, so plan offline maps for those specific stretches rather than assuming any single eSIM reaches everywhere.
Yes, but unevenly. Jazz and Zong both reach the main bazaars in Hunza and Skardu with usable 4G, and Zong is generally the stronger option along the Karakoram Highway corridor itself, while the regional carrier SCOM fills in some gaps that neither national network reaches well. Coverage thins out fast once you leave the main towns for side valleys, and there is no coverage at all at high points like Khunjerab Pass or in Deosai National Park, regardless of which SIM or eSIM you're carrying. A co:sim Pakistan eSIM on Jazz will comfortably cover the towns and the highway drive between them, which is where most travelers spend the bulk of a Gilgit-Baltistan trip. If your itinerary includes multi-day trekking beyond the last town with signal, download offline maps in advance, tell someone your planned route, and don't rely on any data connection reaching you once you're on the trail itself.
Not for data. A data-only eSIM like co:sim's Pakistan plan handles mobile internet on its own, and most travelers only need data for maps, messaging apps, and checking in online. You'd only need a physical local SIM if you specifically require a Pakistani phone number, for example a bank or delivery service that only sends verification codes to a local number. Getting one as a foreigner means bringing your original passport and completing an in-person verification step at an authorised operator store before it activates, which is exactly the counter queue a data-only eSIM is designed to skip. Most short-trip visitors find the eSIM alone is enough, and keep their home number active on their primary line for calls and texts.
Most of co:sim's Pakistan plans are reloadable, meaning you can add more data from the account dashboard without reinstalling a new eSIM profile or requesting a fresh QR code, which matters if you're mid-trip with no reliable Wi-Fi handy to reinstall on. A handful of the shortest, cheapest daily passes are sold as non-reloadable instead, so once that day's allowance runs out, buying a fresh plan is the only option rather than topping up the same one. The plan page states each tier's top-up support clearly before you buy, so you can pick a reloadable option upfront if flexibility matters more to you than shaving a little off the price. If you're unsure how much data a longer trip needs, a reloadable fixed-bundle plan is generally the safer starting point over a single-day pass.
For the vast majority of travelers, yes, data-only is enough. A data-only eSIM covers everything most trips actually need: maps, messaging apps, ride-hailing, translation, and checking email or social media, plus voice and video calls made through apps like WhatsApp, all of which run over data rather than the cellular voice/SMS network. It will not give you a Pakistani phone number, so calls and text messages still route through your home carrier or your primary line; keep that active alongside the data eSIM rather than trying to replace it entirely. The travelers who typically do need an actual local number are those opening a local bank account, receiving Pakistani SMS verification codes, or staying long enough that local contacts expect a number they can reach directly.
Nothing bad, within reason. You can buy well ahead of your trip and install whenever suits you before departure. Because Pakistan eSIM billing starts on first connection rather than at the moment of purchase, an uninstalled eSIM stays untouched until you actually connect to a network. co:sim's general policy is that uninstalled eSIMs can be refunded within 30 days of purchase (some plans that bill immediately at purchase are excluded from this, so check the specific plan page). Once you install and connect, the plan's validity clock starts running, so there's no advantage to installing earlier than you need to: buy ahead for peace of mind, but connect only once you land.
