The best eSIM for Mongolia in 2026. Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Mongolia, priced on the same day: two weeks unlimited for $45.99, a month for $87.99, which to buy.
Prices read on 28 September 2026. Six travel eSIMs sell a plan that works in Mongolia and get most of the traffic for this search. We priced all six on the same day, for a few days in Ulaanbaatar, two weeks on a tour to the Gobi or Lake Khovsgol, and a month, and read the fine print on unlimited. In Mongolia the buckets beat the unlimited plans more often than not. Here is where each one wins.
Ringo Light: Cheapest unlimited for two weeks or a month. Unlimited data at full speed for 2 weeks at $45.99 or 30 days at $87.99, one payment each, nothing renews. Airalo asks $59 for 15 days and $89 for the month, so on the month we are only $1.01 cheaper.
Airalo: Cheapest bucket, cheapest 3 days, cheaper heavy use. 10 GB for 30 days at $18, 20 GB at $29, 50 GB at $49, and 3 days of unlimited at $18, on Mobicom. For heavy use its 15 days at $59 costs less than our 2 weeks with a top-up.
Holafly: Simplest unlimited. Days, not gigabytes, on Mobicom. $19.90 for 3 days, $39.50 for a week; sharing limited to 1 GB a day.
Ubigi: The only one on Unitel. Its Mongolia plans run on Unitel, where the others use Mobicom. 10 GB for 30 days at $59, or $42 on its Asia plan.

Most first trips to Mongolia are two weeks: a few days in Ulaanbaatar, then a driver and a tour south to the Gobi or north to Lake Khovsgol. Only two rivals sell a Mongolia unlimited at all. For 15 days, Airalo asks $59 and Holafly $63.50. For a month, Airalo asks $89 and Holafly $111.90, and Ubigi's World plan is $120 a month for 60 GB at full speed. Ringo Light charges $45.99 for 2 weeks and $87.99 for 30 days, one payment each, nothing renews. On the month that is $1.01 under Airalo, not a big win.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps, which is up to 45 GB over 15 days. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $45.99 top-up. A heavy two weeks with us costs $91.98, more than Airalo's 15 days at $59 or Holafly's at $63.50. A heavy month costs $133.98, more than both of their months. If you will use more than 10 GB in two weeks or 20 GB in a month, Airalo is the cheaper unlimited in Mongolia.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $18 and a week at $35; Holafly $19.90 and $39.50.
Mongolia has four mobile networks: Mobicom, Unitel, Skytel and G-Mobile. Mobicom and Unitel are the two largest. All four cover Ulaanbaatar well, and the provincial towns and most soum centres have a signal. Between them the country is empty, and on the dirt tracks across the steppe, in the Gobi and along much of Lake Khovsgol you will be without a signal for hours at a time, whichever network you are on. Save offline maps and your tour details before you leave the city.
Airalo, Holafly and Nomad ride Mobicom; Ubigi names Unitel. Saily does not name its network. Mongolia is far from the European Union, so a European phone plan roams here at full price. Check yours before you land.
Airalo, $18 for 10 GB. The cheapest 10 GB for 30 days by far, 20 GB for $29 and 50 GB for $49, on Mobicom. 10 GB for 15 days is $16.50.
Nomad, $35 for 10 GB. 20 GB for 30 days at $49, on Mobicom.
Ubigi, $59 for 10 GB. On Unitel. Its Asia plan, which covers Mongolia, sells 10 GB for 30 days at $42 and 20 GB a month at $29, but that one renews monthly until you cancel.
Saily, small buckets only. 1 GB for 7 days at $5.99, 3 GB for 30 days at $17.99, 5 GB for 30 days at $29.99. No 10 GB for Mongolia.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $45.99 and our 30 days with 20 GB for $87.99. In Mongolia a bucket is the better buy for most people: Airalo's 50 GB for 30 days at $49 costs about the same as our 2 weeks and a lot less than our month. Buy Ringo Light only if you want unlimited with no daily cap and will stay near our starting data. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Mongolia it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $45.99, starting with 10 GB, and 30 days at $87.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $45.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is just below this article.
A few days in Ulaanbaatar. Airalo unlimited, 3 days, $18, on Mobicom. Holafly $19.90. Ringo Light sells no 3 days.
Two weeks on a Gobi or Khovsgol tour. Airalo 10 GB for 30 days at $18. Much of a countryside tour has no signal, and 10 GB is plenty for maps and messages in the towns.
Two weeks, unlimited with no daily cap. Ringo Light, 2 weeks, $45.99, the cheapest two weeks of unlimited on the day. If you will use more than 10 GB, Airalo's 15 days at $59 costs less than our $91.98 with the top-up.
A month, working from Ulaanbaatar. Airalo 50 GB for 30 days at $49. For unlimited, Ringo Light 30 days at $87.99 is a dollar under Airalo's month at $89, and stays under it only if you do not need the top-up.
You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
What to do in Mongolia, and what your phone needs for it. Eight places most first trips include, from Ulaanbaatar and Terelj to Kharkhorin, Lake Khovsgol and the Gobi, with the one thing your data does for you at each. Ulaanbaatar has good 4G; much of the countryside has none, so plan ahead.
Sukhbaatar Square, Ulaanbaatar. The central square of the capital, with the Government Palace and its seated statue of Chinggis Khaan on the north side and the statue of Damdin Sukhbaatar in the middle. Street addresses are hard to use in Ulaanbaatar. Send drivers a map pin rather than an address.
Gandan Monastery, Ulaanbaatar. The largest working Buddhist monastery in Mongolia, with a standing statue of Avalokiteshvara more than 25 metres tall inside its main temple. Go in the morning, when the monks chant. Signs are in Mongolian Cyrillic. Translation by camera reads them.
Chinggis Khaan Equestrian Statue, Tsonjin Boldog, east of Ulaanbaatar. A 40 metre stainless steel Chinggis Khaan on horseback, standing on the steppe about an hour's drive from the city. A lift and stairs take you up to a platform on the horse's head. Most people go with a driver on the way to Terelj. Share your live location if you hire one on the day.
Turtle Rock, Gorkhi-Terelj, Gorkhi-Terelj National Park. A granite rock shaped like a turtle in a valley of larch forest and ger camps, the nearest national park to the capital. Stay a night in a ger and ride a horse in the morning. There is a signal in the main valley and not up the side valleys. Download the park in offline maps first.
Erdene Zuu Monastery, Kharkhorin, Ovorkhangai. Founded in 1585 next to the ruins of Karakorum, Chinggis Khaan's capital, it is the oldest surviving Buddhist monastery in Mongolia, inside a wall lined with 108 stupas. It is a long day's drive from Ulaanbaatar. Carry tögrög in cash: small shops and guesthouses on the way often do not take cards.
Lake Khovsgol, Khovsgol Province, near the Russian border. A deep, clear mountain lake that holds most of Mongolia's fresh water, reached by a flight to Moron and a drive to Khatgal. Best from June to August; it freezes solid in winter. There is a signal around Khatgal and little along most of the shore. Book your camp and save the route before you leave town.
Khongoryn Els, Gobi Gurvansaikhan National Park. The singing dunes of the Gobi, a line of sand dunes about 100 kilometres long under the mountains, with camel rides from the ger camps at their foot. Climb them in the late afternoon. Ger camps have little power and patchy signal. Bring a power bank and download what you need in Dalanzadgad.
Bayanzag, the Flaming Cliffs, Omnogovi, the Gobi. Red sandstone cliffs where Roy Chapman Andrews found the first known dinosaur eggs in the 1920s. The colour is strongest at sunset. Coverage out here is thin. Your offline map and your driver's plan matter more than your data.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Mongolia on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile, we could not read its own prices for this country on the day, so it stays out rather than being guessed.

For a bucket, Airalo: 10 GB for 30 days at $18, 20 GB at $29 and 50 GB at $49 on 28 September 2026. For 3 days of unlimited, Airalo at $18. For two weeks or a month of unlimited, Ringo Light at $45.99 for 2 weeks and $87.99 for 30 days, against $59 and $89 at Airalo; with a top-up, Airalo is cheaper.
Airalo, Holafly and Nomad ride Mobicom, and Ubigi Unitel. Saily does not name its network. All of them cover Ulaanbaatar and the provincial towns; out on the steppe, in the Gobi and around Lake Khovsgol there are long stretches with no signal on any network.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Ubigi's World plan after 60 GB a month. Saily and Nomad sell no unlimited here. Holafly states no daily cap for your own phone. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
You can, and it is often cheaper for a long stay. Mobicom and Unitel sell prepaid SIM cards against your passport in Ulaanbaatar, and a local number helps with tour operators and drivers who call or text. A travel eSIM skips the shop visit: you install it before you fly and it works when you land.
