Buy Mobicom unless you are flying west, in which case buy Unitel, and either way understand that you are purchasing a good connection in the places where Mongolians live rather than a connection everywhere you will drive. A prepaid card here is genuinely inexpensive, roughly 15,000 to 25,000 tugrik for the sort of data bundle a two-week trip needs, which is about four to seven dollars at the 2026 rate of around 3,600 to the dollar. The counter staff will register it against your passport in a quarter of an hour and hand you a working line. What none of them will volunteer is that the same line reads no service for six hours at a time on a Gobi track, and that this is not something a better package fixes. Below is what each of the four operators charges, what registration involves, where to top up once you are out in the aimags, and the specific cases where paying several times more for an eSIM still makes sense.

Four Operators, and Why Geography Decides This
Mongolia has four mobile operators for 3.5 million people spread over 1.56 million square kilometres, which works out at roughly two residents per square kilometre and explains almost everything about the coverage you will experience. Mobicom is the largest with around 38 percent of subscribers, majority backed by Japan's KDDI and operating since 1996. Unitel follows near 33 percent, wholly Mongolian owned, running tri-band LTE across 700, 1800 and 2300 MHz. Skytel covers about 80 percent of the population and is essentially an urban proposition. G-Mobile grew out of a rural CDMA network and still trades on that reputation, though its present-day footprint is the thinnest of the four.
Price differences between them are small enough to ignore. All four sell bundles in the same range and none of them will make or break a travel budget, so choosing on cost is a waste of the decision. What actually varies is where the towers are, and that varies by direction: south and east favours Mobicom, the far west favours Unitel, and the capital is a dead heat.
What a coverage percentage means in a country this empty
Operators here publish reach against population, and Mongolian population is not distributed like anyone else's. Half of the country lives in one city. So a network that honestly serves 95 percent of Mongolians can still leave the majority of the territory with nothing on it, because the remaining 5 percent are the ones spread across the parts of the map you are about to drive through. Read those numbers as a promise about towns, not about landscape.
Mobicom: The Default Once You Leave Ulaanbaatar
Mobicom is the card to buy if you are picking one without thinking hard about it. It carries the broadest tower footprint in the country, its parent company Mobicom Networks has strung more than 10,500 kilometres of fibre linking the 21 aimags and 139 soums, and it is the operator most Mongolian tour drivers have in their own phones. It is also the network every mainstream travel eSIM connects through, which is a quiet endorsement of its rural reach from companies with no reason to be sentimental about it.
Tourist packages are sold in round tugrik amounts. A 20,000 tugrik pack has been offered with 600 MB plus 5,000 units of call credit over 15 days, and a 60,000 tugrik pack with 5 GB plus 15,000 units over 30 days. Straight data bundles are better value if you do not need to make local calls, and 2026 pricing puts 5 GB over 30 days near 15,000 to 18,000 tugrik and 10 GB over 30 days near 20,000 to 25,000. The SIM itself is nominal, often a few hundred tugrik or bundled in free with the package.
Where the Mobicom advantage actually shows
Not in Ulaanbaatar, where every network is fine. It shows on the drive south toward Dalanzadgad, on the road out to Kharkhorin, and around the eastern aimags, where Mobicom tends to be the first signal back after a long empty stretch and the last one to go. Over an eight-day Gobi loop that difference is worth perhaps an extra hour or two of connectivity a day, which sounds trivial until it is the difference between sending a message home from a fuel stop and not.
Unitel: The Local Champion and the Western Exception
Unitel is the one Mongolians tend to speak about with a little pride, being entirely locally owned, and it is a serious network rather than a patriotic runner-up. Its LTE runs on 700, 1800 and 2300 MHz with carrier aggregation, and the 700 MHz layer is the one that carries furthest over open ground, which is precisely the terrain this country has in abundance. It has extended service to something like 363 regional localities and covers a high share of the population.
The reason to buy it deliberately rather than by accident is the west. Travellers heading to Bayan-Olgii for the eagle hunters, or into Khovd, repeatedly report Unitel holding a signal where Mobicom has given up. Since every travel eSIM sold for Mongolia runs on Mobicom, a Unitel card is the only way to give yourself a genuinely different network out there, and it is worth twenty minutes in a shop before your domestic flight.
Pricing sits alongside Mobicom. Tourist options have included 40,000 tugrik for 2 GB over 14 days and 60,000 tugrik for 5 GB over 30 days, while the plain data bundles are cheaper: a 3 GB pack valid five days has been sold at airport counters for 15,000 tugrik. As with every operator here, promotions rotate, so read the card at the counter rather than trusting any table on the internet including this one.
Skytel and G-Mobile, and When to Bother
Skytel is the third operator and a perfectly reasonable city network, reaching roughly 80 percent of the population and holding one of the 5G licences the regulator distributed. It sells in the same price band as the big two. The problem for a visitor is that its strength lies in exactly the places where the other three are also strong, so it offers nothing you cannot get elsewhere and gives up ground the moment you head for a soum road.
G-Mobile is the awkward one. It built its identity on rural coverage during the CDMA era and older guidebooks still repeat that, but the modern network is the weakest of the four and travellers who buy it expecting a countryside specialist tend to be disappointed. Treat any advice recommending it on rural grounds as out of date.
The dual-SIM approach some tour drivers use
Mongolian drivers and guides who work the long routes often carry two lines, typically Mobicom and Unitel, because the two networks fail in different places. If your phone takes two SIMs, or one physical SIM plus an eSIM, that trick is available to you for a total of maybe ten dollars and it materially raises the odds of having something usable at any given roadside. The lightest version is a travel eSIM on the Mobicom towers plus a cheap local Unitel card picked up in the capital.
Registering the Card to Your Passport
Mongolia ties prepaid mobile numbers to an identity document, so a passport comes out at the counter before anything activates. The assistant photographs or scans it, enters your details, and the line goes live. Budget between 10 and 30 minutes depending on how busy the shop is and how comfortable the assistant is with English, which varies a great deal between a flagship branch on Peace Avenue and a booth in an aimag centre.
What the counter visit involves
Bring the physical passport, not a photo of it, and bring tugrik in cash even though cards are usually accepted, because the smaller outlets are not always reliable on that. Say which operator you want and how many days you will be in the country, since the packages are structured around 5, 15 and 30 day validities and the staff will steer you toward the right one. Ask them to run a speed test before you leave the shop, which takes ten seconds and catches the occasional dud activation while there is still somebody standing there to fix it.
One practical consequence: you cannot send a travelling companion to collect cards for the group. Everybody who wants a line has to present their own passport in person. On a tour with a fixed pickup time from the airport, that is the detail most likely to make the group late, and it is the single friction a travel eSIM removes entirely.
What Mongolian Prepaid Costs in Tugrik
At roughly 3,600 tugrik to the dollar in August 2026, everything on this list is inexpensive by the standards of a country visitors usually reach via Seoul, Beijing or Istanbul. The spread between the cheapest and dearest option is a few dollars, which is why buying on price here is the wrong instinct.
| Operator | Representative package | Price | Best for |
|---|---|---|---|
| Mobicom | 5 GB, 30 days, data only | Around 15,000 to 18,000 MNT (about 4 to 5 USD) | A fortnight mixing the capital with countryside driving |
| Mobicom | 10 GB, 30 days, data only | Around 20,000 to 25,000 MNT (about 6 to 7 USD) | Longer stays, heavy photo backup, hotspotting for a vehicle |
| Mobicom | Tourist pack, 5 GB plus call credit, 30 days | 60,000 MNT (about 17 USD) | Anyone who needs to phone camps and drivers directly |
| Unitel | 3 GB, 5 days | 15,000 MNT (about 4 USD) | A short western leg as a second line |
| Unitel | Tourist pack, 2 GB, 14 days | 40,000 MNT (about 11 USD) | Light users who want a Mongolian number |
| Any operator | Unlimited, throttled past roughly 20 GB | Around 35,000 MNT (about 10 USD) | A working month based in Ulaanbaatar |
| Travel eSIM | 10 GB, 30 days on the same Mobicom towers | Around 35 USD | Night arrivals, short trips, no passport step, no queue |
Note how much of the gap between the local card and the eSIM is simply the price of convenience rather than a difference in what you receive. The towers are identical. You are paying roughly 28 dollars to skip a counter and to be connected the instant you land, which is an easy yes for some trips and an obvious no for others.
Where to Buy and How to Top Up
Chinggis Khaan International Airport. A SIM desk sits in arrivals past baggage reclaim, generally open from about 6am to 10pm, with separate Mobicom and Unitel positions in the arrivals hall on similar daytime hours. Airport packs run roughly 15,000 to 35,000 tugrik. The critical detail is that these counters do not run overnight, so several of the late inbound flights land to shuttered desks. The Ulaanbaatar Airport guide covers the arrivals layout and the run into town.
Ulaanbaatar city centre. Mobicom, Unitel and Skytel all keep flagship branches around Peace Avenue and Sukhbaatar Square, plus counters in the State Department Store and the larger malls. Buying in town means no queue behind you, an assistant with time to explain the packages, and a chance to compare before committing.
Aimag centres. Every provincial capital has operator outlets and most soum centres have an agent of some kind. This is worth knowing because it means running out of data in the countryside is recoverable at the next town rather than a trip-ending problem.
Topping up out in the aimags
The convenience store chains are the easiest route: CU, Circle K, GS25 and V-Point outlets are everywhere in Ulaanbaatar and present in most provincial towns, and they sell top-ups for all the operators. Each carrier's app also takes a card, which is simpler if you have data left to load it with, and unit-based scratch cards still circulate in smaller places. Load more than you think you need before a countryside leg, because the shop is not the constraint out there, the signal to reach it is.
eSIM or Local SIM for Mongolia?
This decision is unusually clean in Mongolia because the coverage argument, which normally dominates, has been neutralised. Airalo, Holafly and Nomad all ride Mobicom, so an eSIM gives you the same towers as the best local card. What remains is a straight trade between money and friction.
Reasons to buy the local card
Reasons to arrive on an eSIM
The version most repeat visitors settle on is both, and it costs very little. Fly in on an eSIM so the first evening works, then pick up a local card in the capital if the trip is long, if you need a Mongolian number for a tour operator, or if you are flying west and want Unitel in the phone. The full Mongolia eSIM guide sets out what each provider charges for the same connection.
Planning for the Hours With No Network at All
Whichever card ends up in your phone, a serious Mongolia itinerary requires you to plan for being unreachable, and that planning is worth more than the choice of operator. Coverage in the countryside behaves as a series of islands: signal appears as you approach a soum centre, holds while you are there, and vanishes within a few kilometres of leaving. Between islands you may be offline for six hours or more, and on a Gobi or Altai route that is the normal condition rather than the exception.
The four things to do before leaving Ulaanbaatar
Download offline maps of the whole route, not just the destinations, because the interesting failure mode is losing the road rather than losing the town. Save your accommodation details, permits and bookings where they open without a connection. Share your itinerary with somebody at home along with your driver's name and vehicle. And load enough credit or data allowance that you are not trying to top up from a place with one flickering bar.
For anything genuinely remote, a satellite messenger is the honest supplement rather than a gadget indulgence. A Garmin inReach runs on the Iridium constellation, which covers Mongolia properly, and gives two-way texting plus an SOS function that works where no tower exists. Do not substitute your phone for this: Apple's Emergency SOS via satellite reached only about 20 countries as of 2026 and Mongolia was not among them, so the feature that reassures you at home is simply absent here. Mongolian customs does regulate the import of specialised communications equipment, so carry the device openly and declare it rather than tucking it into a bag.
None of this is a reason to avoid the countryside. It is the countryside. But the traveller who buys a plan expecting continuous coverage and the one who buys the same plan expecting islands have completely different weeks, and only one of them is disappointed.
Frequently Asked Questions
Mobicom or Unitel, if I only want one card?
Mobicom for the south, the east and a general countryside loop, since it holds the broadest footprint and is the network every travel eSIM leases. Unitel if your itinerary runs west into Bayan-Olgii or Khovd, where travellers consistently find it hanging on after Mobicom has dropped. In Ulaanbaatar itself the two are indistinguishable in practice. If you can run two lines, the pairing of Mobicom plus Unitel is what many Mongolian tour drivers actually carry, and for the money involved it is a sensible copy.
What will a fortnight of data cost me in tugrik?
Somewhere between 15,000 and 25,000 tugrik for a straightforward 5 to 10 GB bundle, which at about 3,600 tugrik to the dollar is roughly four to seven dollars. Tourist packs bundling call credit cost more, up to 60,000 tugrik for 5 GB plus 15,000 units of calling on Mobicom. The SIM itself is nominal or free with the package. Almost nobody exceeds a 10 GB bundle on a countryside trip, because the terrain does the rationing long before the allowance runs out.
Can somebody else pick up a SIM for me?
No. Every prepaid line must be registered against the passport of the person it belongs to, and the counter staff need the physical document rather than a photograph. That rules out sending one member of a group to collect four cards while the others wait with the luggage. Allow 10 to 30 minutes per person, more if the shop is busy or the assistant's English is limited, and factor it in if your driver is waiting on a schedule.
If my data runs out in the middle of the Gobi, what happens?
You wait until the next town, which on a typical Gobi itinerary means that evening or the following day. Every aimag capital and most soum centres have an operator agent or a convenience store selling top-ups, and the chains CU, Circle K, GS25 and V-Point are widespread. The operator apps work too, though there is a chicken-and-egg problem in using an app to buy the data you have run out of. Load generously before leaving the capital and the situation does not arise.
Does a Mongolian card work on the train to Beijing or Irkutsk?
Only as far as the border. There is no roaming arrangement that quietly extends a Mongolian prepaid line into China or Russia, so it stops at Zamyn-Uud or Sukhbaatar and you are on whatever the next country provides. Coverage along the Mongolian half of the route is reasonable by local standards, with 3G along most of it and 4G near the larger towns, and there is no onboard WiFi on these trains. If you are crossing, buy a regional or multi-country plan rather than assuming your Mongolian card will follow you.
