Mongolia is probably the destination where you have to take the connection most seriously before leaving home. In Ulaanbaatar, you'll have plenty of 4G to order a taxi or upload photos of Sükhbaatar Square, but as soon as the asphalt ends and the steppe, the Gobi Desert, or a remote ger camp begins, the signal becomes a luxury. That's why it's wise to decide how you're going to get internet in Mongolia. In this guide, I compare all the real options for tourists: roaming, hotel Wi-Fi, local Mongolian SIM (Mobicom, Unitel, or Skytel, which are purchased with a passport), and eSIM. And I dedicate an entire section to what really matters here: where there is coverage and where you'll be out of communication.
Internet in Mongolia: The Quick Answer
For a tourist, an eSIM is the most convenient way to get internet in Mongolia: it activates in minutes on the Unitel or Mobicom network, avoids airport paperwork in Ulaanbaatar, and works as soon as you land. A local SIM is slightly cheaper; roaming is convenient but expensive.
That's the short conclusion, but in Mongolia, geography adds a nuance. It's one of the least densely populated countries on the planet, with vast empty spaces between cities, and that's the crux: connection here is a very serious matter. In Ulaanbaatar and provincial capitals, any option works, with reliable 4G and cheap data. The problem arises as soon as you venture into the steppe, the Gobi, or the northern lakes, where no card guarantees continuous signal.
That's why my recommendation has two layers. For cities and main routes, an eSIM on Unitel or Mobicom is more than enough, and you'll be connected from minute one. For remote stretches, no SIM works magic: it combines what little mobile network there is with satellite Wi-Fi at some camps and, above all, with downloaded offline maps. In the following sections, I break down each option with real prices and coverage so you can make an informed decision.
All Options at a Glance
Here's the complete picture. There are five realistic ways to connect in Mongolia, and not all of them carry the same weight or cost the same. Focus less on the price and more on the "but" column: in such a vast country, what's a minor detail in Ulaanbaatar can leave you without anyone to contact in the middle of the steppe.
| Option | Approximate Price | Process | Its Big "But" |
|---|---|---|---|
| Carrier Roaming | €6-15/day or up to several €/MB | None | Very expensive and with very limited data |
| Free Wi-Fi (hotel, cafes) | Free | None | Almost only in Ulaanbaatar and where you are stationary |
| Local SIM (Mobicom, Unitel, Skytel) | ~€4-12 for several GB | Medium: passport and in-person registration | Queue, card swap, and you lose your number |
| Portable router (pocket Wi-Fi) | Uncommon in Mongolia | Medium: rental and return | Depends on the same mobile network that fails outside |
| Travel eSIM | From ~€10 for several GB | None: QR and ready | Requires compatible mobile phone |
As you can see, the local Mongolian SIM wins on price, but it involves in-person registration and airport queues. Portable routers are barely rented here and don't solve the underlying problem: they rely on the same network that shuts down off-route, as I explain in the eSIM vs. pocket Wi-Fi comparison. The eSIM is a very convenient middle ground: the only one that keeps you connected without visiting a counter or touching your phone's slot.
Roaming with Your Spanish Carrier
Roaming is the "do nothing" option and, precisely because of that, the most expensive. Mongolia is outside the European Union's "roaming like at home" zone, so your Spanish gigabytes don't travel with you: you enter international rates, where the bill skyrockets without warning. For pay-as-you-go, some operators charge several euros per megabyte, which can turn an afternoon of maps in Ulaanbaatar into a three-digit shock.
To sweeten the deal, they sell daily bundles. Typical rates outside Europe range from €6 to €15 per day, and it's worth checking the fine print: some offer only 100-500 MB daily, a pittance if you're using navigation on the road. Do the math: two weeks in Mongolia at €10-15/day is €140-210 just for data, and the bundle is useless in the steppe, where there's no network to connect to.
My advice: treat it as an emergency network and activate it only if something goes wrong. Check your carrier's app before you leave to find out your exact applicable rate. If you want detailed numbers, how much international roaming costs and the eSIM vs. roaming comparison will be useful.
Hotel Wi-Fi: Almost Only in Ulaanbaatar
The second temptation is to rely on free Wi-Fi, and in Mongolia, this has a geographical catch. In Ulaanbaatar, there's plenty: almost all hotels offer it, as do cafes and restaurants in the center; premium accommodations boast connections suitable for video calls. The problem is that it only works where you are stationary, and a trip through Mongolia is precisely the opposite: moving hundreds of kilometers in a 4x4 on dirt tracks.
Outside the capital, the story changes completely. In provincial capitals and some villages, you'll find Wi-Fi in hotels and guesthouses, but it's slower and more erratic. But in the ger camps of the steppe or the Gobi, it's common for there to be no Wi-Fi at all. Some boutique camps and lodges install satellite internet, but it's usually slower and more expensive than in the city, and sometimes it costs extra.
The honest conclusion: Wi-Fi is a good support for planning your route or uploading photos at night from your Ulaanbaatar hotel, but as a main plan, it's a disaster, because you need it precisely when you don't have it: negotiating with a driver or notifying that you're running late to the camp. In the capital, use it as a complement; in the interior, assume it won't be there.
Local Mongolian SIM: Mobicom, Unitel, and Skytel
In Mongolia, three operators are of interest to you. Mobicom is the largest, with coverage for about 95% of the population and a market share close to 40%. Unitel is the second, covering about 88% of the population, was the first to deploy national 4G LTE, and is reputed to be the most reliable for inland routes. Skytel is cheaper but often slower. For tourists leaving the city, Unitel or Mobicom are the safest bet; the process is simple but in-person.
To register any Mongolian SIM, you need your passport. You can buy them at Chinggis Khaan International Airport in Ulaanbaatar (there's a counter in arrivals), at official centers, or in the thousands of stores across the country. These are my references for Unitel's tourist plans for 2026:
- Tour SIM 5: 3 GB for 5 days for about 15,000 MNT (~€4).
- Tour SIM 10: 5 GB for 10 days for about 25,000 MNT (~€7).
- Tour SIM 30: 20 GB for 30 days for about 40,000 MNT (~€11).
- The SIM card alone costs around 3,000-15,000 MNT, and Mobicom has similar tourist combos.
The "but" isn't the price, but the logistics: you take out your Spanish SIM, insert the new one, lose your number (goodbye to bank SMS unless you have Dual SIM), and register after a long flight. Cheap, yes, but with paperwork.
eSIM: The Option I Recommend
This is where the eSIM shines in Mongolia, and not just for marketing: it gives you the same local network as a store-bought SIM, but without the drawbacks. An eSIM is a digital card that already lives inside your phone. You buy the Mongolia plan from home, receive a QR code, scan it, and you're good to go. No queues, no passport registration, no filling out forms after a long flight with a layover in Istanbul or Seoul.
eSIMs for Mongolia rely on the Unitel and Mobicom networks, so your coverage in Ulaanbaatar and on main routes is the same as with a local SIM: where the operator reaches, you reach. The difference isn't in the signal, but in how you access it, without paperwork and active upon landing. In terms of price, plans are around €10 for several GB. It's not as cheap as a local card, but the difference is a few euros in exchange for not losing your number or your time.
Another key advantage: with Dual SIM, you keep your Spanish number active for bank SMS while data goes through the eSIM. If it's your first time, read what an eSIM is and then the eSIM guide for Mongolia, where I explain the installation and activation step-by-step.
Local SIM vs. eSIM, Face to Face
This is the comparison that truly matters in Mongolia, because roaming is ruled out by price alone and Wi-Fi isn't enough to live outside the capital. The table pits the two contenders against each other, and you'll see that convenience determines the outcome: how much paperwork you do, whether you swap cards, and whether you keep your Spanish number.
| Criterion | Local SIM (Mobicom / Unitel) | Travel eSIM |
|---|---|---|
| Price | ~€4-12 for several GB | From ~€10 for several GB |
| Documents | Passport and in-person registration | None |
| Where to buy | Airport or official store, in person | Online, from home, before flying |
| Time to get data | Counter queue plus registration | Minutes: scan QR and ready |
| Network used | Mobicom, Unitel, or Skytel | The same, usually Unitel or Mobicom |
| Your Spanish number | You lose it if your phone has only one slot | Remains active with Dual SIM |
| Coverage inland | Depends on the operator; Unitel reaches further | The same network, with identical off-route limits |
My take: if you're going for a long month with a backpack and want to maximize value, a local Unitel SIM pays off. If you're going for one or two weeks and value arriving with data without losing your number, the eSIM clearly wins. In both cases, choose an operator with good rural coverage: in Mongolia, coverage matters more than pennies. If in doubt, check out the eSIM vs. local SIM comparison.
Coverage by Area: Ulaanbaatar, Gobi, and Khövsgöl
It's important to go zone by zone, because in Mongolia, the signal follows the people: where there's concentrated population, there are antennas, and where there isn't, there's radio silence. Very high population coverage figures are cited (over 95% 4G in inhabited areas), but that's misleading, because people live in very few spots of an immense territory. This is what you can expect:
- Ulaanbaatar: the best in the country. Reliable 4G throughout the city, with 5G emerging in specific areas, and free Wi-Fi in hotels, cafes, and restaurants. You won't notice a lack of connection here.
- Provincial capitals and towns: there's 4G or 3G in urban centers and along main roads, enough for maps, messaging, and banking. Speed is lower than in the capital.
- Gobi Desert: very scarce coverage. You'll catch some signal in towns like Dalanzadgad, but between dunes and camps, it's normal to have nothing.
- Lake Khövsgöl (Jövsgöl): there's some network in Mörön and in the village of Khatgal, but around the lake and in the taiga, the connection is intermittent or non-existent.
The practical rule: as soon as you move away from a populated center, expect to lose signal. Unitel has a reputation for reaching further along tracks and is a favorite of many drivers for long routes.
Steppe, Desert, and Ger Camps: The Key Point
This is the most important section and where disconnection is simply the norm. In the open steppe, in the Gobi Desert, and in ger or nomadic family camps, mobile coverage is scarce or non-existent for hours of travel. It's not an isolated failure: it's to be expected in a country where you can drive half a day without encountering a power pole, let alone a cell tower.
What do you do then? Combine several things. Choose the operator with the best rural reach (Unitel is usually the benchmark) to snatch a signal in the villages you pass through. Don't count on camp Wi-Fi: many tourist gers have none, and those that do often rely on slow, sometimes paid, satellite internet. And, most importantly, prepare everything offline before leaving Ulaanbaatar.
My advice for the interior: download your route maps offline, let your family know you'll be out of coverage for days, and treat every signal point as a gift, not a given. In Mongolia, disconnecting is not a travel risk: it's part of the journey.
For very remote journeys, some travelers carry a satellite internet terminal (like Starlink Roam), which provides connection almost anywhere with a clear sky. It's an expensive, niche solution, but without it, you'll be out of communication between destinations, and that needs to be planned, not endured.
How Much Data Do You Need in Mongolia?
The million-dollar question before buying any plan. The short answer: for cities, less than you fear; for the interior, it almost doesn't matter, because the limitation is coverage, not gigabytes. It's best to calculate by days and by actual usage. In Ulaanbaatar and provincial capitals, you'll mostly use maps, messaging, some social media, and banking; heavy video and photo backups are best left for hotel Wi-Fi. This table gives you a reference by activity and day.
| Daily Activity | Approximate Consumption |
|---|---|
| Google Maps and navigation | ~50-100 MB/day |
| WhatsApp and messaging | ~20-50 MB/day |
| Social media (normal scrolling) | ~150-300 MB/day |
| Uploading photos and some videos | ~200-400 MB/day |
| Banking, email, and app calls | ~30-60 MB/day |
Adding up normal tourist usage, you'd use about 400-800 MB per day when you have network. For a week between Ulaanbaatar and short excursions, 3-5 GB is enough; for two or three weeks based in the capital, a 10-20 GB plan is more than sufficient. And here's the Mongolian nuance: don't inflate your plan thinking about the steppe or the Gobi, because you'll barely use data there due to no network. Calculate your gigabytes for areas with coverage, round up, and download your route maps offline.
Frequently Asked Questions
Is there coverage in the Gobi Desert?
Very scarce. You'll find some signal in towns like Dalanzadgad, but between dunes, camps, and long journeys, it's normal to be without network for hours. Expect to be out of communication and download maps offline before you go.
Which operator is best for traveling inland Mongolia?
Unitel has a reputation for reaching further along tracks and is a favorite of many drivers. Mobicom is the largest and is comparable. Skytel is cheaper but often falls short outside cities.
Do I need a passport to buy a SIM in Mongolia?
Yes. To register any Mongolian SIM, you'll need your passport. They can be bought at Ulaanbaatar Airport, official centers, or stores across the country, and registration is done in person at the counter.
Does an eSIM work in Mongolia?
Yes, and very well in areas with coverage. eSIMs for Mongolia use Unitel or Mobicom networks, so your signal in Ulaanbaatar and on main routes is like a local SIM, but without queues and active as soon as you land.
How many GB do I need for two weeks in Mongolia?
For normal use based in the city —maps, messaging, social media, and some photos— 10 GB will be more than enough for two weeks. You'll barely use mobile data in the countryside because there's no network, so don't inflate your plan thinking about the steppe.
Is there Wi-Fi in ger camps?
As a general rule, no. Many tourist gers in the steppe and Gobi do not have Wi-Fi. Some boutique camps install satellite internet, which is slower and more expensive than city internet, and sometimes comes with a fee. Don't count on it as your primary plan.
Can I use WhatsApp with an eSIM in Mongolia?
Yes, where there is coverage. WhatsApp works with data, not with the voice network, so it works the same with a Mongolian eSIM. With Dual SIM, your Spanish number remains active for bank SMS.
Conclusion
Having internet in Mongolia is easy in Ulaanbaatar and a matter of managing expectations once you leave the city. In the capital and on main routes, any option using Unitel or Mobicom will give you plenty of 4G; a local SIM is very cheap but requires a passport and in-person registration, and roaming will cost you €140-210 for two weeks. Therefore, for most people, an eSIM is the answer: the same local network, no queues, and keeping your number. For the steppe, the Gobi, and ger camps, assume that the signal will barely show up and rely on offline maps. Install it before you take off and you'll be connected as soon as you land.
