1 · The short answer

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.

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.

4 · 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.

5 · If you want unlimited for two weeks or a month: Ringo Light, narrowly

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 is unlimited data at full speed for the whole trip.

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.

6 · Which network works best in Mongolia

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.

7 · If you want a data bucket: Airalo

  • 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 is unlimited for $45.99 and our 30 days unlimited 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 if you want unlimited with no daily cap. We would rather you read that here than at checkout.

8 · What Ringo Light is

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 and 30 days at $87.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.

The card to buy it is further up this page, just after the side-by-side table.

9 · Pick by trip

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.

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.

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.

10 · Frequently asked questions

Which eSIM is cheapest for Mongolia?+
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.
Which Mongolian network will my travel eSIM use?+
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.
Is an unlimited eSIM really unlimited in Mongolia?+
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 is unlimited data at full speed.
Should I buy a local SIM in Ulaanbaatar instead?+
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.

11 · How we compared, and our sources

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.

Written and priced by the Ringo team. Prices change often; if you spot one that has moved, tell us through the contact page and we will update the table.
