Cheapest eSIM for Mongolia: the numbers
As of 31 August 2026, 15:21 GMT, the cheapest eSIM for Mongolia is Connect Me Guru with 10 GB for 1 Day at $30.40. That is $3.04 per GB, the best rate of the 90 plans we compare from 9 providers. 33 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which mobile networks does Mongolia have?
MobiCom claims 95% population coverage and Unitel about 88%, but Mongolia is the least densely populated country on earth and large areas between towns have no signal at all. All provincial capitals have at least 3G.
- MobiCom: MobiCom is Mongolia's biggest operator, founded in 1996 with Japan's KDDI, holding over a third of the market and claiming network coverage of 95% of the population.
- Unitel: Unitel is the second operator with about a third of the market, covers roughly 88% of the population, and ran the country's first 5G test station on Sukhbaatar Square in 2022.
- Skytel: Skytel is a smaller operator that historically ran 3G in Ulaanbaatar plus a CDMA network in the countryside, and it was included in the 5G licence handout.
- G-Mobile: G-Mobile is the smallest operator, built on CDMA to serve remote countryside areas, and holds only a minor market share together with Skytel.
Mongolia has no notable MVNOs, so travel eSIMs connect through the main networks, usually MobiCom or Unitel.

Is 5G available in Mongolia?
Mongolia officially launched 5G in May 2025 after the regulator distributed licences to MobiCom, Unitel and Skytel, with a target of 70% population coverage by 2027. For now 5G works mainly in Ulaanbaatar.
How much data do you need in Mongolia?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Mongolia right now:
Are unlimited eSIMs for Mongolia really unlimited?
Not always. 19 of the plans above are sold as unlimited. Most unlimited travel plans have a fair use rule. You get full speed for a daily amount, often 1 to 5 GB, then the speed drops to around 1 Mbps until the next day. That is fine for messages and maps but slow for video. If you know how much data you use, a fixed plan with a low price per GB is usually the better deal. That is why we rank by price per GB and not by labels.
eSIM or a local SIM at the airport in Mongolia?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Mongolia starts at $30.40 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Mongolia eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Mongolia
SIM registration is mandatory, so you need your passport or another ID at the point of purchase.
MobiCom, Unitel and Skytel all run counters in the arrivals area at Chinggis Khaan International Airport, with tourist packages roughly 5 to 20 US dollars. Counters close in the evening, so late arrivals may find them shut.
For Gobi trips and countryside tours expect long stretches with zero signal between towns, so download offline maps before leaving Ulaanbaatar. MobiCom sells tourist combo bundles with data and calling credit that can be extended up to 90 days.
Mongolia Travel eSIM FAQ
Everything you need to know about using an eSIM in Mongolia
What is the cheapest eSIM for Mongolia?
Right now the cheapest option ranked by price per GB is Connect Me Guru with 10 GB for 1 Day at $30.40. That works out to $3.04 per GB. Prices change often, so the table above always shows the current order.
Which networks will my eSIM connect to in Mongolia?
The plans we compare connect to Mobicom. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Mongolia eSIMs support 5G?
The networks our plans use in Mongolia currently run on 4G. That is enough for maps, messaging, video calls, and streaming in most cases.
Can I top up my Mongolia eSIM if I run out?
Yes. 33 of the 90 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
How many GB do I need for a week in Mongolia?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is Connect Me Guru at $16.56.
