If you're calculating how many GB to buy for your trip to Mongolia, I'll tell you something that isn't usually mentioned on eSIM pages: you'll spend far less here than you think, because for a good part of the trip you simply won't have coverage. Mongolia is the destination where I've most often seen people buy 20 GB and return home with 17 untouched. I'll give you the exact figure, a table by profile, and the specific details that truly change the number: the steppe, the Gobi, yurt camps, and the peak of Naadam in July.
How many GB you need for Mongolia: the figure
For a 10-day trip to Mongolia, most people will be fine with 3 GB: you'll spend entire days in the steppe and the Gobi without coverage. If you work from Ulaanbaatar or upload videos daily, increase to 10 GB. Less than you might imagine.
That's the answer, and I won't hide behind nuances. The typical Mongolia itinerary involves two or three nights in Ulaanbaatar and the rest on the road: Gobi, Karakorum, the Orkhon Valley, Khövsgöl. In these stretches, your phone will spend most of its time searching for a network and finding nothing. It's not that you "spend little": it's that you physically cannot spend for hours on end.
My quick rule for Mongolia, and I apply it in reverse compared to almost any other destination: only count the city days. A 12-day trip with 3 nights in the capital and 9 in the countryside behaves, in terms of data, like a 4 or 5-day trip in any European country.
- 1-2 GB: short getaway or very rural trip, downloaded maps and WhatsApp.
- 3 GB: the sensible option for a 10-14 day classic circuit. What most people buy.
- 5 GB: if you upload photos daily and make video calls home from the hotel.
- 10-20 GB: real remote work from Ulaanbaatar, or a family sharing multiple phones.
If you're coming from the general article in the cluster about how much data you need for travel, you'll see here that Mongolia pulls the average down. And I think it's more honest to tell you that than to sell you a large package you won't use.
Why Mongolia lowers the number: the real coverage map
Mongolia has three and a half million inhabitants in a territory three times the size of Spain. The mobile network is where the people are, and people are in very few places. This draws a consumption map with three very clear tiers that should be understood before choosing a plan.
Ulaanbaatar works well: fast 4G, Wi-Fi in cafes, hotels, and shopping centers, and a decent cafe scene with connectivity. This is where you'll spend almost all your data. Provincial centers (the aimags: Dalanzadgad for the Gobi, Kharkhorin, Mörön) have reasonable 4G or 3G, although the speed drops as the town fills up. And then there's the rest of the country: steppe, Khongoryn Els dunes, Yol Canyon, yurt camps two hours from nowhere. There, you can spend two or three days in a row without a single bar.
The local operators are Mobicom, Unitel, Skytel, and G-Mobile, and of these, Mobicom covers the most ground outside the cities. You don't always choose which network an eSIM connects to, but it's worth knowing: if your companion has a signal at a roadside stop and you don't, they're almost certainly on a different network.
In the steppe, the question isn't "how many gigabytes do I have left?", but "when will I see a cell tower again?". It completely changes how you plan your trip.
If you want details on operators, bands, and connection options, you'll find it broken down in the internet in Mongolia guide. Here, we'll continue with gigabytes.
What each activity consumes, in real MB
Before deciding, it's good to have the figures in front of you. These are the ones I use, rounded up so you don't run short. Pay attention to the last row: video is the only thing that can empty a data plan in an afternoon.
| Activity | Approximate Consumption | On a trip to Mongolia |
|---|---|---|
| Online navigation maps | 3-5 MB per hour | Almost irrelevant; and offline, zero |
| WhatsApp: daily messages and photos | 10-25 MB per day | The base consumption for most people |
| Video call (WhatsApp or similar) | 5-12 MB per minute (300-700 MB/h) | Only possible in the city; 10 min a day is already 60-120 MB |
| Social media scrolling | 300-800 MB per hour | The real data hog: Reels and TikTok |
| Uploading compressed photos to social media or chats | 1-3 MB per photo | 50 photos ≈ 100 MB. Not much |
| Automatic photo backup to cloud in original quality | 3-6 MB per photo, 30-80 MB per short video | Here's where it adds up: 200 photos ≈ 1 GB |
| Music streaming | 40-150 MB per hour | Adds up on long journeys; better to download |
| Video streaming (480p / 720p / 1080p) | 350 MB / 900 MB / 2-3 GB per hour | What ruins a small data plan |
| Email and normal browsing | 10-20 MB per hour | Negligible |
The takeaway is simple: chatting and browsing are practically free, and video is expensive, both watching it and uploading it in original quality. If you want the detailed breakdown with more apps and scenarios, I have it in the data usage statistics by activity. For Mongolia, these nine rows are sufficient.
Recommendation by profile and duration
This is the table I'm going to give you. It's calculated for the usual Mongolian itinerary (2-4 nights in Ulaanbaatar and the rest on the road), not for someone staying a month in the capital. If your trip is entirely city-based, take the column on the right and go up a tier.
| Profile | 5 days | 10 days | 15 days | 30 days |
|---|---|---|---|---|
| Tourist using maps and WhatsApp | 1 GB | 2 GB | 3 GB | 5 GB |
| Photographer and social media user | 2 GB | 3-5 GB | 5-8 GB | 10-15 GB |
| Digital nomad / remote work | 5 GB | 10 GB | 15-20 GB | 30 GB or more |
| Family sharing a phone | 2-3 GB | 5 GB | 8 GB | 15 GB |
Three important nuances to read it correctly:
- Digital nomads don't fit in rural Mongolia. If you need to work, plan to do so from Ulaanbaatar or a provincial center. No data plan can fix an area without a cell tower.
- Families spend less than they fear if they share the connection from one phone: offline maps and chats consume a negligible amount, and the rest of the day you're looking out the window.
- An organized tour lowers the number. Local drivers have their own lines, and camps inform you where there's a signal; you end up using less than expected.
My practical recommendation: if you're torn between 3 and 10 GB for two weeks, take the 3 GB and save the money for a good ger camp. Topping up takes minutes; getting gigabytes back doesn't exist.
Landscape and wildlife photos: the unseen expense
Mongolia is a photographer's dream destination. You'll be snapping away like crazy: dunes at sunrise, herds of horses, yaks, vultures, the cleanest sky you've ever seen. And here's the most common misunderstanding I encounter: taking photos doesn't consume data. Not a single bit. What consumes data is uploading them.
The problem is that many phones upload automatically. Google Photos, iCloud, or gallery backup activate as soon as you get a signal, and if you've been three days without coverage, your phone has a queue of 300 photos and 12 videos waiting. You connect to 4G upon entering Dalanzadgad, and in twenty minutes, you've used up a gig and a half without even touching your phone.
What to do, in order of importance:
- Go into your photo app settings and set backup to Wi-Fi only. It's a toggle and saves you half your data plan.
- If you still want to back up on the go, upload them in reduced quality, not original. The difference is 6 MB to 1.5 MB per photo.
- Videos are best uploaded from your hotel in Ulaanbaatar. A one-minute 4K clip can weigh more than 50 photos.
- To send to family, WhatsApp or Telegram compress and cost you 1-3 MB per image. Perfect for daily use.
With automatic backup deactivated, a two-week trip of non-stop photography fits comfortably within 3 GB. With it activated in original quality, not even 20 GB will be enough. That single setting is more decisive than the size of the data plan you buy.
Battery life matters more than gigabytes
I'll be clear: in Mongolia, the scarce resource isn't data, it's electricity. Yurt camps near Ulaanbaatar are usually connected to the grid and have power 24 hours a day, but in the Gobi and remote areas, electricity comes from solar panels or a generator that runs for a few hours at dusk, typically between six and ten in the evening. Outside that window, there's no outlet to be found.
And there's a technical aggravating factor: a phone without coverage uses more battery than a connected one, because the antenna is constantly boosting power searching for a network. Eight hours of 4x4 driving across the steppe with your phone in normal mode can leave it at 20% without you having done anything.
What works:
- Airplane mode while driving. You can still use the camera and downloaded maps with GPS activated, which doesn't require a network. You gain hours of battery life.
- 20,000 mAh or larger power bank. It's the most useful accessory for the entire trip, ahead of any data plan.
- European-type adapter. Mongolia uses 220 V and outlets compatible with ours in most places, but check yours beforehand.
- Charge during the generator window, and if your ger doesn't have an outlet, in the dining room or reception of the camp.
In other words: 20 GB are useless on a phone at 4%. If you have to spend money on something before leaving, make it a decent power bank and a cable that won't fail.
What to download before leaving Ulaanbaatar
This is the habit that will save you the most data in Mongolia: spending half an hour in your capital city hotel, with Wi-Fi, to download everything before getting into the 4x4. Take advantage of that night in the city and don't leave it for the road, because there's no road on the road.
| What to download | Approximate size | Why it matters in Mongolia |
|---|---|---|
| Offline maps (Google Maps, Maps.me, or OsmAnd) | 150-400 MB depending on area | Essential: GPS works without a network, so you can navigate the steppe |
| Offline Mongolian language pack for translator | 40-70 MB | The alphabet is Cyrillic; the translator's camera saves menus and signs |
| Music and podcasts for journeys | 100-300 MB for a few hours | 6-8 hour car journeys are the norm |
| Series or movies for the camp | 300-700 MB per episode | It gets dark late in summer, but there's nothing to do after dinner |
| Reservations, insurance, ticket PDFs, and agency contact | Less than 10 MB | Having them locally prevents cold sweats at an airport without a network |
| System and app updates | Several GB if they fire off | Do them via Wi-Fi or disable them: they're the biggest silent data drain |
That last point deserves a warning: automatic app updates are the dumbest way to burn through an entire data plan in a country where data is scarce. Set them to "Wi-Fi only" before leaving home and forget about it. You can find more tips like this in the guide on how to save data on a trip.
Naadam in July and other calendar peaks
If you're traveling in July, there's one date that dictates everything: Naadam, the national festival of wrestling, archery, and horse racing, whose main events in Ulaanbaatar in 2026 are from July 11th to 13th. It's the best time to see the country and also the worst time to expect a fast network.
What this means in practice:
- Saturated network in and around the stadium. Tens of thousands of people recording video in the same spot means the connection will be patchy, even if you have full coverage.
- You'll spend more that day. Between uploading videos, checking schedules, and coordinating with your group, a Naadam day can easily use 300-600 MB, compared to 30-50 MB on a normal day in the countryside.
- Local Naadam festivals in the provinces are held around the same time and are more authentic, but they are usually in areas with poor coverage. There, you'll spend zero again.
- Everything gets full. Accommodation, domestic flights, and cars. If you're going during those dates, book well in advance.
The rest of the calendar also influences things. In winter, tourism almost disappears, and roads become complicated, meaning you'll spend more hours inside a vehicle and less with your phone in hand. In the peak summer season, however, you'll have more stops in towns and more opportunities to connect.
My advice if you're going to Naadam: upload your video that same night from the hotel, not live from the stands. It will be faster, use less data, and you'll enjoy the spectacle instead of struggling with a loading bar.
How to know your real consumption before traveling
Everything above is an average. Your exact number is already in your pocket and can be checked in two minutes, without installing anything. It's the most honest method I know to avoid buying too much or too little.
- On Android: Settings → Network & internet → Mobile data usage. You'll see monthly consumption and a breakdown by app.
- On iPhone: Settings → Mobile Data. Scroll down to the app list; remember to reset statistics at the beginning of a month for a clean reading.
- Divide by 30 and you'll have your real daily consumption at home.
- Multiply by the number of travel days and then subtract between 40% and 60% for the days without coverage in the Mongolian itinerary.
An example with round numbers: if you use 9 GB a month, that's 300 MB a day. A 12-day trip would be 3.6 GB under normal conditions; in Mongolia, with seven or eight days in the steppe, you'll be around 1.5-2 GB. Buy 3 GB and you'll have plenty of margin.
Two upward corrections that do make sense: if you watch a lot of video using data at home and don't plan to change that habit, don't subtract as much. And if you're going to share the connection with more people in your group, add up each person's consumption, although in Mongolia it's normal for the person sharing to end up using less than expected because others are also out of signal half the time. If you've never used this technology, here I explain what an eSIM is and how to activate it.
How to stretch your data and what happens if you run out
I'll start with the latter, which is the main concern. If you run out of data in Mongolia, it's not a big deal: you can top up from the app or website in a couple of minutes, as long as you have coverage or Wi-Fi at that moment. That's why I say it's better to buy too little and top up than to buy too much: unused gigabytes are not refunded, and buying 20 GB "just in case" in a country where you'll be without signal for days is a waste of money.
The only precaution: top up when you still have some balance or when you're in an area with Wi-Fi, not when you're at zero in the middle of the Gobi. If you know you'll be cutting it close, do it the night before at the camp or in the last town with a signal.
To make your data last longer:
- Activate data saving in your system settings and low-power mode within social media and streaming apps.
- Deactivate automatic video playback on Instagram, X, Facebook, and TikTok. This setting offers the best effort-to-benefit ratio.
- Always use offline maps. Navigating with a downloaded map consumes practically zero data.
- Backups only via Wi-Fi, as we've already discussed, and updates too.
- Use hotel and cafe Wi-Fi in Ulaanbaatar for heavy tasks: uploading your photo gallery, long video calls, downloads.
- Check your data usage every two or three days in your settings. Thirty seconds and you'll know if you're on track.
With these six habits, a modest data plan will last an entire trip. And if you have data left over, even better: it means you were looking at horses instead of your screen, which is exactly why people go to Mongolia.
Frequently Asked Questions
How many GB do I need for 10 days in Mongolia?
3 GB is more than enough for most people. The classic itinerary includes several days without coverage in the steppe or the Gobi, so actual consumption is concentrated during evenings in Ulaanbaatar. If you make daily video calls or upload videos, increase to 5 GB.
Is there coverage in the Gobi Desert?
Very little and very intermittent. There's 4G in Dalanzadgad and some larger towns, but between destinations, you might go two or three days without a single bar. Assume you'll be disconnected and download maps before you leave.
Do yurt camps have Wi-Fi?
Some do, many don't. Those near Ulaanbaatar usually have Wi-Fi and 24-hour electricity; remote ones operate with generators or solar panels for a few hours at dusk, and if they offer internet, it's usually satellite, slow, and sometimes paid. Don't count on it for work.
Can I work remotely from Mongolia?
Yes, but only from Ulaanbaatar or provincial centers. The capital has fast 4G and cafes with good connections. On the road, it's unfeasible: it's not a matter of gigabytes, it's that there's no network. Plan meetings for city days and notify about your disconnected windows.
Will my photos upload automatically and drain my data?
Yes, if you don't disable it beforehand. When you regain coverage, your phone will suddenly upload the accumulated queue from days without network. Set backups to "Wi-Fi only" and the problem disappears: it's the most cost-effective setting for the whole trip.
What happens if I run out of data in the middle of the country?
You wait until you have signal or Wi-Fi and top up in two minutes. You don't lose your number or settings. The risk is running out of data in an area with no coverage, so top up with enough buffer from the last town or camp with a connection.
Do I need more data if I travel during Naadam?
A little more, but nothing dramatic. A festival day uses around 300-600 MB compared to 30-50 MB on a day in the countryside. An extra half a gigabyte beyond your calculation should cover you; and the network will be slow due to congestion even with full coverage.
Does the same calculation apply to the north, in Khövsgöl?
Yes, and even less. Mörön has reasonable coverage, but the lake area and northern forests are just as poorly served as the Gobi, if not worse. Same principle: count city days and assume the rest are lost.
Conclusion
Mongolia is a destination where I confidently tell you to buy sparingly. 3 GB for ten to fifteen days covers most people, because half the trip takes place where there's no cell tower anyway. Increase to 5 GB if you upload photos and make video calls daily, and only to 10-20 GB if you're working from Ulaanbaatar or sharing the connection with several people.
And most importantly: disconnection here isn't a plan failure, it's part of the plan. Download your maps, set photo backups to Wi-Fi mode, bring a big power bank, and be prepared to go two days without answering messages. It's one of the few things you can still truly buy by traveling far away today.
Once you have your data needs clear, activate your eSIM for Mongolia before leaving home and arrive at Chinggis Khaan Airport with data from the very first minute. You can choose your data plan and have it ready in five minutes on the Mongolia eSIM page.
