There is exactly one reason to buy a Lao SIM rather than an eSIM, and it is not the money, even though the money is remarkable. It is Unitel. Roughly half the country's lines sit on it, it runs upwards of 9,000 base stations, and it is the only operator with real towers in the northern provinces, which is where Laos gets interesting and where the international eSIM brands cannot follow you. A starter card costs around 10,000 kip, thirty gigabytes for a month sits near 200,000, and the whole transaction takes about five minutes provided you have your physical passport in hand. What follows is what each of the four operators actually charges in 2026, what the registration involves, and the specific situations where paying several times more for a travel eSIM is still the smarter move.

Four Operators, One That Matters Outside Town
Laos supports four mobile networks across a population of about 7.7 million, which is more competition than the country's size suggests and less choice than it sounds, because the split is heavily weighted. Unitel, run jointly by the Lao state and Vietnam's Viettel, holds roughly half the market on more than five million lines. Lao Telecom, the operator from 1996 that everyone shortens to LTC, sits at around a third with over three million. ETL is the other state-owned network, cheaper and smaller. TPlus, which traded as Beeline Laos under VimpelCom before its rebrand, holds roughly a tenth of the market and is popular with younger Lao subscribers.
What separates them for a visitor is not price, because all four are cheap enough that the difference between them is a couple of dollars a fortnight. It is where the towers are. National figures from late 2024 put 2G at about 97 percent of the population, 3G at 85 and 4G at 78, and that last gap is entirely made of the mountains, the river valleys and the villages a traveller is most likely to want to reach.
Why the north is a separate question
Coverage in Laos follows the road, and the road follows the Mekong and Route 13. Vientiane, Vang Vieng, Luang Prabang, Savannakhet and Pakse all sit on that spine and all four networks serve them adequately. Step off it, up the Nam Ou toward Nong Khiaw and Muang Ngoi, or into the Phongsali trekking country, and the honest answer is that the operator list shrinks to one. Northern provinces carry the steepest build economics in the country, with mountain access roads and thin population, so the towers that exist there exist because Unitel put them up.
Unitel
Unitel is the default recommendation from almost every Lao person you ask and from most travellers who have been further north than Vang Vieng. It covers better than 90 percent of the population on 4G, holds the national Speedtest award with an average download around 37.5 Mbit/s, and was the first operator in the country to switch on commercial 5G, though that 5G remains parked in central Vientiane.
The reason to care is what happens on the edges. Where ETL fades within a few kilometres of the highway, Unitel tends to hold a bar into the side valleys, at the top of Kuang Si, along the road to Nong Khiaw and on a decent share of the Phongsali circuits. Nothing covers a trekking route properly, but Unitel is the network you want when you climb back out of one.
Unitel prices in 2026
A starter SIM runs about 10,000 kip, roughly 55 cents, usually with a small data allowance and some credit thrown in once your passport is registered. Data bundles sit around 50,000 kip for 5 GB over 30 days and about 200,000 kip for 30 GB over the same period, which is close to eleven dollars. Tourist packs sold at airport stalls cluster between 50,000 kip and the equivalent of fifteen dollars depending on duration. Promotions move constantly, so read the current card at the counter rather than trusting any published table, this one included.
Buy Unitel if you are going north, staying more than a couple of weeks, or simply want the choice that requires no further thought. It is not the cheapest of the four and the difference is measured in the price of a coffee.
Lao Telecom (LTC)
Lao Telecom is the oldest operator in the country, founded in 1996 as a state venture with Thai partners, and it is the network every travel eSIM buyer ends up on without realising, because both Holafly and Nomad ride it. Its 4G footprint is broad, its village reach is better than ETL's, and it is dependable along the entire Vientiane to Vang Vieng to Luang Prabang run. Measured speeds sit a little below Unitel and it is early into 5G in the capital.
Its packages are aggressively priced for short bursts. Bundles in the region of 20,000 kip for 5 GB over three days and 30,000 kip for 7 GB over a week are common, and a 90 GB monthly package has sold for around 110,000 kip, which works out near twelve dollars for more data than most visitors could burn in a season. If your Laos is the classic overland loop, LTC and Unitel are close enough that either will do.
The point where LTC weakens is the same place ETL does, just further along the road. Coverage thins once you are properly off the highway network, and it is not the operator locals name when the conversation turns to the far north. It is also the network with the contract to build mobile coverage along the Laos-China Railway, which is worth knowing if you plan to ride that line in 2027 or later.
ETL and TPlus: The Budget Two
ETL is the state's second network and the one Airalo's Laos plan runs on, sold under the Pak Ou Mobile name. It is genuinely quick where it exists, second in the country on measured download at around 24 Mbit/s, and its footprint follows roughly 80 percent of the population along the main highways. That phrasing does a lot of work. ETL is a highway network. On Route 13 between the big towns it is fine. On a dirt road up a side valley it is the first of the four to disappear.
TPlus is the smallest of the serious operators, about a tenth of the market on roughly a million lines, strong enough in the cities and openly weaker in border regions and rural districts. It sells entertainment-flavoured data bundles aimed at young Lao subscribers rather than at visitors, and there is little reason for a traveller to seek it out.
When the budget pair is the right call
If you are in Laos for four days, sleeping in Vientiane and taking the train up to Luang Prabang for the weekend, ETL will serve you perfectly and cost almost nothing. The failure mode is not that it stops working, it is that it stops working on the exact afternoon you are trying to find a homestay in a village with no street signs. Weigh the two dollars you saved against that.
The Passport Scan Is Not Optional
Every prepaid line in Laos must be registered against an identity document, and all four operators enforce it at the counter. Bring the physical passport, because most shops will not accept a photograph on your phone or a photocopy, and that catches out travellers who have locked the real thing in a guesthouse safe.
How the purchase runs
1. Hand over the physical passport. A driving licence or a scan on your phone will usually be refused.
2. Pick a package. Airport stalls and city shops both steer visitors toward the tourist bundles without being asked, and staff at the bigger branches manage the conversation in English.
3. Pay in kip. Cash is the norm and small notes are appreciated, though larger shops in Vientiane take cards.
4. Wait while the assistant registers and activates the line, usually two or three minutes, and confirm data is flowing before you walk away.
Two practical consequences follow. One person cannot buy a stack of SIMs for a group, because each line ties to its own holder. And the registration is the reason you cannot pick a card off a supermarket shelf and be online in thirty seconds the way you can in some neighbouring countries.
This step is precisely what a travel eSIM removes, which is worth weighing rather than dismissing. It is also why plenty of visitors land on an eSIM, spend a few days working out how long they are really staying, and only then walk into a Unitel shop.
Lao Prepaid Options Side by Side
| Operator | Representative package | Price | Best for |
|---|---|---|---|
| Unitel | 30 GB, 30 days | Around 200,000 LAK (near 11 USD) | The north, long stays, anyone who wants the widest reach |
| Unitel | 5 GB, 30 days | Around 50,000 LAK | Light users staying a few weeks |
| Lao Telecom | 7 GB, 7 days | Around 30,000 LAK | A single week on the main corridor |
| Lao Telecom | 90 GB, 30 days | Around 110,000 LAK | Remote workers based in Vientiane or Luang Prabang |
| ETL | Tourist packs, 1 to 30 days | Roughly 2 to 20 USD equivalent | Short highway-only trips on the tightest budget |
| TPlus | City data bundles | Roughly 2 to 15 USD equivalent | Little reason for a visitor to choose it |
| Travel eSIM | 10 GB metered, or unlimited by day | Roughly 25 USD, more for unlimited | Short trips, evening arrivals, no passport step, multi-country routes |
The starter card adds about 10,000 kip on top, which is a rounding error against any of these bundles. What actually decides the total is validity: buying three separate weekly packs costs noticeably more than one monthly bundle, so if you are staying a month, buy the month.
Where to Buy a SIM in Laos
Airport arrivals halls. Wattay in Vientiane and Luang Prabang both have telecom stalls sitting past immigration, typically Unitel and Lao Telecom side by side. The catch that catches people is hours: these are small stalls staffed around flight times rather than around the clock, and a late evening landing can easily mean waiting until morning. The Luang Prabang Airport guide covers where exactly the stalls sit in that terminal.
Carrier shops in town. Unitel and Lao Telecom have proper branches in Vientiane, Luang Prabang, Vang Vieng, Savannakhet and Pakse, and these carry the full range of bundles rather than the two or three tourist packs an airport stall stocks. Prices are also a little lower than the airport, though the gap is small.
Minimarkets and phone stalls. Scratch cards and top-up credit are sold almost everywhere, including small village shops, so recharging is rarely a problem once your line exists. Buying a new registered SIM in a village shop is a different matter and often is not possible.
Topping up once you are here
The simplest method is a scratch card from any minimarket: buy the denomination you want, dial the operator's top-up code, enter the number underneath the foil. Each carrier also has an app, and Unitel's is the most usable in English. Mobile money and QR payments have spread quickly in Lao towns, so if you have a Lao account the top-up can happen entirely on the phone.
eSIM or Local Card for Laos?
This site sells eSIMs and will still tell you that for a long or northern Laos trip the local card wins, and specifically that Unitel wins, because none of the big travel eSIM brands can put you on it. Here is the split as honestly as it can be drawn.
Buy local when
Buy an eSIM when
The middle path is the one most people who return to Laos settle on. Land on an eSIM so the first evening works, then add a Unitel card in town if the itinerary turns out to have mountains in it. Two lines cost so little here that the redundancy is close to free, and on a road where the next town is two hours away it is worth having. The Laos eSIM guide sets out which international provider rides which network.
Practical Lao Connectivity Notes
Download offline maps before you leave a provincial capital. Whatever you bought, the road between Lao towns has stretches where nothing works, and unlike a city gap these last for tens of kilometres rather than a couple of minutes.
The train is a dead zone. The Laos-China Railway threads 198 kilometres of tunnel across 75 separate bores, carries no onboard WiFi, and will not have meaningful open-air coverage until the Lao Telecom build finishes its first phase at the end of 2026. Load your downloads at the station.
The Mekong slow boat is a longer dead zone. Two days from Huay Xai to Luang Prabang with an overnight halt at Pakbeng, almost no reception in the gorge and no power sockets on board. Carry a battery pack and cash, because cards are no use on that route.
Borders end everything. A Lao SIM stops at the Friendship Bridge, at Boten and at the Vietnamese passes, and so does a Laos-only eSIM. If your route is regional, buy regionally.
WiFi is genuinely everywhere in the towns. Guesthouses, cafes and restaurants across Luang Prabang and Vientiane hand out passwords without being asked, which is why most visitors here use far less mobile data than they budgeted for. The Luang Prabang city guide covers what that looks like on the peninsula.
Frequently Asked Questions
Which of the four Lao operators should a visitor actually pick?
Unitel in almost every case where you are choosing a physical SIM, because it holds better than 90 percent population coverage, the fastest measured speeds in the country and the only usable presence in the northern provinces. Lao Telecom is a close second and perfectly good along the Vientiane to Luang Prabang corridor, with some very cheap short bundles. ETL is quick but effectively a highway network. TPlus is aimed at local subscribers rather than travellers. If you will never leave the main road, any of them works. If you might, take Unitel.
What does a Lao SIM cost me in total for a fortnight?
Very little. The starter card is around 10,000 kip and a 30 GB monthly bundle on Unitel sits near 200,000 kip, so the whole thing lands close to eleven or twelve dollars for far more data than a two-week trip needs. Lao Telecom will do a week of 7 GB for around 30,000 kip, which is under two dollars. The real cost of a local SIM in Laos is not money, it is the twenty minutes and the passport scan at a counter that might be closed when you land.
Can I buy a Lao SIM without showing my passport?
No. Registration against an identity document is mandatory and the operators enforce it, so the assistant will scan your passport before the line activates. Most shops insist on the physical booklet rather than a photo or a copy, which trips up people who leave the original in a hotel safe. It takes a couple of minutes and is not intrusive, but it does mean each traveller must be present for their own card, and it is the single friction point a travel eSIM removes.
How do I add more data once I have run out?
Scratch cards are the standard answer and they are sold in minimarkets, phone stalls and even small village shops right across the country. Buy the denomination you want, dial your operator's top-up code, key in the number under the foil and the credit lands immediately. Each carrier also runs an app, with Unitel's being the most navigable in English, and QR-based mobile money has spread quickly through Lao towns if you have a local account to pay from.
Will a Lao SIM still work if I cross into Thailand or China?
It stops at the border. There is no regional roaming arrangement across mainland Southeast Asia comparable to the one inside the EU, so a Lao prepaid line goes quiet at the Friendship Bridge, at the Boten crossing into China and at the eastern passes into Vietnam. A Laos-only eSIM behaves identically. If your route strings countries together, buy a Southeast Asia regional plan deliberately rather than assuming, and carry small US dollar notes for the crossing fees themselves.
