Mongolia's verified eSIM floor is $0.98 a gigabyte, but its unlimited plans cost far more than its neighbours'
Airalo's 50 GB Mongolia plan is $49, the same as in four other markets priced the same day. Its 30-day unlimited plan is $89, against $69 in China. Eighteen prices, read off the checkout on 17 August 2026.
One seller, eighteen prices, one date
We hold plan data for exactly one eSIM provider in Mongolia: Airalo. Eighteen plans, all verified, read off airalo.com on 17 August 2026. That is the whole of our Mongolia coverage, and it is not a market survey. Saily, Holafly, Nomad, eSIMCard and eSIM Go all sell travel eSIMs; none has been priced here yet, so none appears below with a figure beside it.
Airalo lists these plans as Mongo Mobile & Fiber. That is Airalo's own retail product name, not a carrier. Airalo publishes no host network for Mongolia, and none for any other country, so we cannot tell you which operator the eSIM attaches to.
The metered ladder
| Data | Days | Price | Per GB |
|---|---|---|---|
| 1 GB | 3 | $4 | $4 |
| 3 GB | 3 | $7 | $2.33 |
| 3 GB | 7 | $7.50 | $2.50 |
| 5 GB | 7 | $9.50 | $1.90 |
| 5 GB | 15 | $10 | $2 |
| 5 GB | 30 | $11 | $2.20 |
| 10 GB | 7 | $15 | $1.50 |
| 10 GB | 15 | $16.50 | $1.65 |
| 10 GB | 30 | $18 | $1.80 |
| 20 GB | 15 | $26 | $1.30 |
| 20 GB | 30 | $29 | $1.45 |
| 50 GB | 30 | $49 | $0.98 |
Twelve metered plans, from 1 GB to 50 GB, with nothing above. The rate falls steadily: $4.00 a gigabyte at 1 GB, $1.50 at 10 GB, $0.98 at 50 GB. Stepping up a rung is always the cheapest data on the page — 20 GB over 30 days is $29 and 50 GB over 30 days is $49, so the last thirty gigabytes cost $20, about 67 cents each.
The metered plans are regional; the unlimited ones are not
Four other markets were priced the same afternoon — China, Hong Kong, Macau and Kazakhstan. All five carry the same 50 GB plan at the same $49 and the same 1 GB plan at the same $4, and Mongolia's metered ladder tracks the group closely in between: its 10 GB over 30 days is $18, exactly Hong Kong's, and its 20 GB over 30 days is $29, again exactly Hong Kong's.
The unlimited plans behave completely differently. Mongolia is the outlier of the five, and by a wide margin.
| Unlimited | Mongolia | China | Hong Kong |
|---|---|---|---|
| 3 days | $18 | $11.50 | $12.50 |
| 7 days | $35 | $27 | $29.50 |
| 15 days | $59 | $49 | $49 |
| 30 days | $89 | $69 | $71 |
Mongolia's 7-day unlimited costs $35, which is what ten days of unlimited costs in each of the other four. Its 30-day plan is $89 against $69 in China. And it is the only one of the five whose 15-day unlimited is not $49.
That contrast is the most interesting thing in the data. The metered ladder is pinned at both ends to the same figures as four unrelated markets — Airalo charges $49 for 50 GB over 30 days in 18 of the 56 countries where we hold a 50 GB price at all, from Iceland to Bangladesh. The unlimited ladder is not pinned to anything, and Mongolia's is dear. We do not know why, and Airalo does not publish how it sets country prices, so we are not going to explain it for them.
As a floor, $0.98 is mid-table on this site: Thailand's verified floor is $0.55 a gigabyte and Austria's $0.58, while Kenya reaches $4.60 and Fiji $4.70 among the 94 countries covered.
Skip unlimited here
The practical consequence is easy. In Mongolia the metered plans beat the unlimited ones at almost every duration.
- 50 GB over 30 days is $49. Unlimited over 30 days is $89 — $40 more for whatever you use beyond 50 GB.
- Unlimited over 15 days is $59, which is $10 more than the 50 GB plan that runs twice as long.
- Unlimited over 3 days is $18, against $7 for 3 GB over the same 3 days and $15 for 10 GB over 7.
Unless you are genuinely likely to clear 50 GB in a month, the metered column is where the value is.
Which plan for which trip
- A few days in Ulaanbaatar. 3 GB over 3 days at $7, or 5 GB over 7 days at $9.50 for slack.
- A week. 10 GB over 7 days at $15, the point where the rate first drops to $1.50.
- Two weeks. 20 GB over 15 days at $26, at $1.30 a gigabyte.
- A month, or a phone feeding a laptop. 50 GB over 30 days at $49, the only plan here under a dollar a gigabyte.
What this page does not cover
The obvious question about Mongolia is coverage — whether a travel eSIM is any use outside the capital, on the road, or in the Gobi. We hold no data on that at all. Nobody here has tested a connection in Mongolia, we have no coverage measurements, and since Airalo publishes no host network we cannot even tell you whose footprint to look up. If that matters for your trip, treat it as an open question rather than trusting a page that answers it confidently without having measured anything.
We hold no local SIM data either: no counter prices, no shop advice, no registration rules, no operator names. And nothing for the other five sellers — if one of them beats $0.98 a gigabyte here, we would not know it, and neither would a page listing all six with figures nobody read. That distinction is the whole of how we test. Our Airalo page covers the company across every country we hold, and the cheapest eSIM plans puts this $0.98 beside every other rate on the site.
Common questions
Which eSIM is cheapest in Mongolia?
Airalo's 50 GB plan over 30 days at $49 is the lowest rate we hold, at $0.98 a gigabyte. Airalo is also the only provider whose Mongolian prices anyone here has read — Saily, Holafly, Nomad, eSIMCard and eSIM Go have not been priced in Mongolia, so we cannot tell you whether one of them is cheaper.
Are the unlimited plans worth it in Mongolia?
Rarely. Unlimited over 30 days is $89 against $49 for 50 GB over the same period, and unlimited over 15 days is $59 — $10 more than the 50 GB plan that lasts twice as long. Mongolia's unlimited prices are the highest of the five markets we read that day, so unless you expect to pass 50 GB, the metered plans are better value.
Will an eSIM work outside Ulaanbaatar?
We do not know. Nobody here has tested a connection anywhere in Mongolia, we hold no coverage data, and Airalo publishes no host network for the country, so we cannot even point you at an operator's coverage map. It is a real question for travel outside the capital and we would rather say we have not measured it than guess.
Why is 50 GB the same $49 in Mongolia as in Hong Kong?
Because it is not a Mongolian price. Airalo charges $49 for 50 GB over 30 days in 18 of the 56 countries where we hold a 50 GB figure, including Iceland, Colombia and Bangladesh. A single number spanning that range of markets reflects the seller's pricing policy rather than what capacity costs in any one of them.
