Airalo is my starting point for a Mongolia trip that needs a clear fixed-data budget: 5 GB for 30 days costs $21, 10 GB costs $34, and 20 GB costs $49. It lists Mobicom. If you want unlimited data, compare its daily fair-use limit with Holafly’s hotspot allowance before choosing. For a different named network, Ubigi lists Unitel.
The route matters. A few days in Ulaanbaatar, a Gobi circuit, a stay near Lake Khövsgöl and an expedition into the Altai create different opportunities to use mobile data. Buying a bigger bundle cannot solve a lack of signal. Start with your overnight stops, the data you need between them, and a plan for working offline.
This guide keeps five practical options: Airalo, Holafly, Ubigi, Jetpac and Saily. It compares their current plans without assuming that a shared carrier produces identical speeds, or that Unitel automatically wins in western Mongolia. For a longer regional trip: Asia 2026 · Uzbekistan 2026 · Thailand 2026.
Quick answer: choose by trip need
- Fixed data: start with Airalo’s $21 / 5 GB / 30 days or $34 / 10 GB / 30 days.
- Unlimited: Airalo is $39 for seven days, with 3 GB of high-speed data per day before slowing to 1 Mbps. Holafly is $40.90 for seven days and permits 1 GB per day of hotspot sharing.
- Another named network: Ubigi offers Unitel, with 1 GB / seven days at $16.
- Selected app benefits: Jetpac’s eligible 3 GB and larger packs keep certain apps available after the data allowance ends, where network coverage exists.
- Small plans and app features: Saily starts at $5.99 for 1 GB / seven days. Its optional US phone number is a separate paid service.
Install your Mongolia eSIM before you travel
Check that your exact phone model supports eSIM and is carrier-unlocked. Install the profile while you have a stable internet connection, keep the instructions available offline, and read the selected plan’s activation policy. Installation and the start of paid validity are not always the same event.
- Install the provider app and eSIM before departure, then label the line clearly.
- On arrival, select the travel eSIM for mobile data and enable roaming on that line if the provider requires it.
- Turn off data roaming and automatic data switching on your home line to avoid accidental roaming use.
- Test a map, message and browser page before leaving the airport or hotel Wi-Fi. Keep the eSIM installed if troubleshooting is needed.
You can keep your home SIM available for your normal number if your device supports both lines, but your home carrier may charge for calls, texts or roaming. For a fuller setup walkthrough, use How to Activate an eSIM. For a long stay or a Mongolian local number, compare a local operator’s current visitor offer and registration requirements instead of assuming a travel data plan includes voice service.
Mongolia eSIM prices: compare the same allowance and validity
The table uses current USD offers from the five providers. A seven-day 1 GB plan is not interchangeable with a three-day plan, and unlimited products have their own conditions. These are listed prices, not prices after reader codes.
Fixed-data plans
| Allowance | Airalo | Ubigi | Saily | Jetpac |
|---|---|---|---|---|
| 1 GB | $5 / 3 days | $16 / 7 days | $5.99 / 7 days | $7 / 4 days; $4 new-user offer shown |
| 3 GB | $13 / 3 days; $15 / 7 days | $32 / 15 days | $17.99 / 30 days | $14 / 7 days |
| 5 GB | $19 / 7 days; $20 / 15 days; $21 / 30 days | Not listed in country range | $29.99 / 30 days | $21 / 30 days |
| 10 GB | $27.50 / 7 days; $30.50 / 15 days; $34 / 30 days | $59 / 30 days | Not listed | $40 / 30 days, sale shown |
| 15 GB | Not listed | Not listed | Not listed | $52 / 30 days, sale shown |
| 20 GB | $47 / 15 days; $49 / 30 days | Not listed | Not listed | $72 / 30 days |
| 30 GB | Not listed | Not listed | Not listed | $85.50 / 30 days, sale shown |
| 40 GB | Not listed | Not listed | Not listed | $100 / 30 days |
Airalo’s current country catalog stops at 20 GB in the fixed-data view checked. The old 50 GB / $49 recommendation no longer matches that view. Jetpac’s $4 entry offer is shown with new-user conditions and its own promotion; do not assume it stacks with ANDREONDIGITAL. At 5 GB / 30 days, Airalo and Jetpac both list $21 before discounts.
Unlimited plans
| Duration | Airalo | Holafly |
|---|---|---|
| 1 day | Not listed | $9.50 |
| 3 days | $19.50 | $20.90 |
| 5 days | $30.50 | $31.50 |
| 7 days | $39 | $40.90 |
| 10 days | $46.50 | $47.90 |
| 15 days | $63 | $64.90 |
| 30 days | $99 | $115.50 |
Read the limits before choosing unlimited. Airalo’s Mongolia details specify 3 GB of high-speed data per day, followed by 1 Mbps. Holafly permits 1 GB per day of sharing with other devices; its fair-use terms can reduce speed, so do not treat unlimited as a promise of unrestricted high-speed laptop use. Jetpac also lists a 30-day unlimited option at $351, with 3 GB per 24 hours at normal speed and then up to 1 Mbps. Compare those conditions and your actual usage before spending that much.

Mobicom, Unitel and what a network listing tells you
| Provider | Official Mongolia network information | How to use it |
|---|---|---|
| Airalo | Mobicom | Compare the selected package, validity and limits. |
| Holafly | Mobicom Corporation | The same named carrier does not establish equal roaming speed or priority. |
| Ubigi | Unitel | A different listed network can be useful to investigate for your route. |
| Jetpac | MobiCom in the selected country-plan panel | Recheck if switching to a regional or global product. |
| Saily | Carrier not named on the checked country page | Ask support before buying if a specific network is essential. |
Do not read this table as a test of Mongolia’s operators. A roaming product can differ in routing, allowed radio technology, network selection and traffic management even when it names the same carrier. Nor does Ubigi’s Unitel listing make it the only eSIM on that network across the whole market. The official information checked does not establish a winner for Bayan-Ölgii, Khovd or the Altai.
If your guide recommends a particular operator for specific camps, confirm that the exact eSIM package can use it. A second line on a different network can add an option when one network is unavailable, but two lines cannot guarantee service in a place with no reachable coverage. Ubigi’s official partner list is a useful cross-check.
The five providers in detail
1. Airalo: a practical fixed-data starting point
I would start here for a trip where maps, messages and occasional uploads are the priority. Choose the validity that covers your whole stay: its 10 GB plan is $27.50 for seven days, $30.50 for 15 days or $34 for 30 days. A shorter plan saves money only if it will not expire while you still need it.
At 20 GB / 30 days, $49 is lower than Jetpac’s listed $72 for the same allowance and validity. At 5 GB / 30 days, however, the two tie at $21. This is a useful package comparison, not a claim that Airalo is the cheapest provider everywhere.
The selected Mongolia plan is data-only, starts when it connects in the destination, and allows up to 365 days to activate according to the checked panel. The unlimited version has the 3 GB daily high-speed allowance explained above. Check tethering and top-up details for the pack you select. I have used Airalo in Portugal, not Mongolia. More context: Airalo Review 2026 · Airalo vs Nomad.

This retained video is a general setup reference. Use it to understand installation and the app; it is not a Mongolia field test and does not validate current package prices.
2. Holafly: unlimited data with flexible duration
Holafly suits travelers who prefer choosing a number of days instead of managing a fixed allowance. Its one-day option is $9.50, seven days costs $40.90 and 30 days costs $115.50. Compare the checkout total after any eligible reader discount, especially on a short trip where the difference from Airalo is small.
The detail that matters for a laptop or travel companion is the 1 GB per day hotspot allowance. Phone data and shared data are not the same allowance. Fair-use terms still apply to unlimited use. Holafly also advertises Always On backup data, with its own coverage and conditions, and 24/7 support. Check whether that benefit covers your next destination rather than assuming it does.
I have used Holafly in Portugal, Turkey and Thailand. Those experiences do not demonstrate Mongolian coverage. Its own Mongolia page warns about weak or absent signal on remote steppe, desert and mountain routes. Full review: Holafly Review 2026.

The existing video helps explain the service and setup. The Mongolia product terms in this article take priority over older prices or broader marketing claims in a video.
3. Ubigi: a named Unitel option
Ubigi is useful to consider when you specifically want a plan listing Unitel. Its country range includes 1 GB for seven days at $16, 3 GB for 15 days at $32, and 10 GB for 30 days at $59. The 10 GB tier means the older description of only two small Mongolia plans is no longer accurate.
Its value here is a different named network, not a proven western coverage advantage. Ask your guide or accommodation about actual stops before paying extra for a second profile. A small backup bundle can expire before a long tour ends, so validity needs to fit when you will use it.
Ubigi is data-only and allows data sharing. SmartStart begins the plan on connection in a covered destination; the cited product terms give six months to activate. Top-ups are available through the app. I have not personally tested Ubigi. Read Ubigi Review 2026 for wider context and Ubigi’s current plan details for the terms.

This is a general installation and app reference. It does not prove that Unitel is stronger at a particular western stop or that Ubigi has exclusive access to it.
4. Jetpac: selected app benefits on eligible packs
Jetpac ties Airalo at $21 for 5 GB / 30 days before discounts. Larger listed packs include 10 GB at a $40 sale price and 20 GB at $72. The 1 GB / four-day entry is shown at $7 with a $4 new-user promotion, so treat the lower number as conditional.
On eligible purchases of 3 GB or more, Jetpac says WhatsApp chat, Google Maps navigation, Uber and Grab remain accessible after the general allowance is exhausted. That still requires mobile coverage. It cannot restore a signal on a remote road, and it does not mean unlimited access to every feature in those apps.
Jetpac permits hotspot sharing, sells voice packs through its app and does not include SMS in its data service. SmartDelay requires flight registration and eligibility; verify current rules before relying on lounge access. Unactivated packs are available for three months from purchase. I have not personally tested Jetpac. Use ANDREONDIGITAL at checkout to check eligibility; no universal discount percentage or stacking is assumed.
Jetpac installation video
The retained setup video gives context for the app and installation. Current Mongolia allowances, offer conditions and network information are listed above; a benefit after data exhaustion is not a coverage guarantee.
5. Saily: small data plans and app security features
Saily offers 1 GB for seven days at $5.99, 3 GB for 30 days at $17.99, and 5 GB for 30 days at $29.99. The 3 GB package can be useful for light use across a longer trip because its validity is longer than the seven-day 3 GB Airalo and Jetpac options.
The Mongolia page permits hotspot sharing without an additional hotspot cap and describes automatic activation on arrival with the line and roaming enabled. It gives a 180-day activation period. Security features include controls such as ad blocking and virtual location, but do not treat them as evidence of faster or broader Mongolian coverage.
The optional phone number is a US +1 number, not a Mongolian +976 number. It requires a separate subscription and a suitable calls/text plan. Saily’s Mongolia page lists calls and SMS options, while its help pages explain that callers may pay international rates to reach the US number and some verification services may not accept it. Confirm destination support, calling direction and charges before using it for drivers or camps. I have not personally tested Saily. More detail: Saily eSIM Review 2026 and Saily’s phone-number help page.

This existing video is a general app and setup reference. The optional number is a separate product with its own charges and eligibility, and the video is not evidence of Mongolia coverage.
Plan for the steppe, Gobi and remote overnight stops
Holafly’s official Mongolia coverage guidance distinguishes populated places from desert, mountain and remote-road areas where service may weaken or disappear. That is a reason to prepare offline, not a basis for drawing exact dead zones on a map. No provider page checked here establishes reliable service at every ger camp, trail or scenic stop.
- Before leaving Ulaanbaatar: download the full route, translation tools, bookings, tickets and your guide’s contact details.
- For the Gobi circuit: ask your guide which stops have usable mobile service or Wi-Fi and when you should expect to be unreachable.
- For Lake Khövsgöl and mountain routes: check the particular accommodation and road, not just the nearest town name.
- At camps: ask whether Wi-Fi exists, where it works and whether large uploads are practical. Do not assume satellite Wi-Fi is standard.
- For remote work: schedule demanding calls from a confirmed connection and carry local copies of essential files.
Western Mongolia, Naadam and the Trans-Mongolian route
For Bayan-Ölgii, Khovd and the Altai, ask a guide with current knowledge of your itinerary which operator is useful at each overnight stop. Ubigi’s Unitel listing is a concrete option to investigate. It is not proof that Unitel always beats Mobicom in the west. Keep meeting arrangements and your route usable without a live signal.
For Naadam or another busy event, agree on meeting places beforehand, keep a charged power bank and save tickets locally. Mobile service can be affected by crowds, but buying an unlimited plan does not buy priority access to congested towers.
On a cross-border journey, a Mongolia-only plan covers Mongolia. Confirm the exact countries in any regional or global alternative, especially China and Russia, and install the next plan while reliable internet is available. A product called Asia does not necessarily include Mongolia. Do not assume a train connection or border service is operating solely because an eSIM covers the country.
Practical Mongolia eSIM tips
Choose validity for the full period you need data, including an extra transfer day if appropriate. Estimate the allowance from your habits: messaging and occasional maps differ from tethering a laptop, cloud backups or uploading video. Disable automatic photo backups and large app updates on cellular data if the plan is small.
Save the provider’s setup instructions and support channel. If a connection fails, check the selected data line and roaming settings, then follow the provider’s network/APN instructions. Avoid deleting the profile while traveling unless support directs you to do so.
Keep a backup way to contact your guide and discuss communications for any remote expedition. An eSIM is ordinary mobile service. For broader trip planning: Asia 2026 · International Travel eSIM Guide · Uzbekistan 2026 · Thailand 2026 · Vietnam 2026.
FAQ: best eSIM for Mongolia
What is the best eSIM for Mongolia in 2026?
Airalo is a useful starting point for fixed data: 5 GB / 30 days is $21, 10 GB is $34 and 20 GB is $49. Holafly offers unlimited by the day, Ubigi lists Unitel, Jetpac has selected app benefits on eligible packs, and Saily has small plans with optional paid phone-number service. Choose using route, validity and usage rather than a universal coverage ranking.
Which networks do these Mongolia eSIMs use?
Airalo and Holafly list Mobicom, Jetpac lists MobiCom for the selected Mongolia plan, and Ubigi lists Unitel. Saily does not name its carrier on the checked country page. A listed network does not prove exclusive access, identical performance or coverage at a particular camp.
Will an eSIM work in the Gobi and the Mongolian countryside?
Service can be weak or unavailable on remote desert, steppe and mountain routes. Ask your guide and accommodation about exact stops, download maps and bookings, and agree on expected periods offline. The illustrations are planning aids, not measured coverage maps.
Which unlimited Mongolia eSIM is cheaper?
Before discounts, Airalo is $39 for seven days and $99 for 30 days; Holafly is $40.90 and $115.50 for those durations. Airalo slows to 1 Mbps after 3 GB of high-speed data per day. Holafly permits 1 GB per day of hotspot sharing and fair-use terms apply. Compare the eligible checkout price and conditions.
Should I choose a Mongolia eSIM because it advertises 5G?
Check the exact package and network details rather than assuming a general 5G badge guarantees access on your route. Device support, roaming permissions and local coverage all matter. For trips outside populated areas, route preparation and offline access are more useful buying criteria than a headline speed label.
Can I get a phone number with a Mongolia travel eSIM?
Saily offers an optional US +1 number with a separate subscription and call/text plans; its Mongolia page lists calls and SMS options. It is not a local Mongolian +976 number. Confirm destination support and charges, including what callers pay to reach it. Ordinary data plans use internet calling and messaging apps rather than supplying a local number.
Can I use the same eSIM in Mongolia, China and Russia?
Only if the exact purchased package lists every country you need. A Mongolia-only package does not provide data in China or Russia. Check each country and activation rules before buying a regional or global product, and install additional profiles while you have reliable internet.
Final Verdict: choose for your route and data budget
For a typical trip with modest mobile use, I would compare Airalo’s fixed packages first. The 10 GB / 30-day plan at $34 is a straightforward budget, while the $21 / 5 GB plan suits lighter use. Jetpac ties that 5 GB price and is worth comparing if its eligible app benefits matter to you. Neither choice guarantees connectivity on an isolated road.
For unlimited use, compare Airalo and Holafly at your exact duration. Seven days costs $39 versus $40.90 before discounts, but the daily high-speed and hotspot rules are different. Someone working from a laptop should treat those limits as central to the decision.
Choose Ubigi when Unitel access has a clear purpose on your itinerary. A guide’s current route advice can make a second network worth considering. Saily is another practical option for a small allowance lasting 30 days, its app features or its separate US-number service. The right plan is the one whose allowance, validity and conditions fit the trip you actually booked.
Reader codes: Airalo ANDRE15: 15%; Holafly ANDREONDIGITAL: 5%; Ubigi ANDREONDIGITAL: 10%; Saily ANDREONDIGITAL: 10%. Jetpac ANDREONDIGITAL is retained for checking eligibility at checkout, with no unverified percentage. Offers may have customer, package or promotion exclusions; compare the final total and do not assume codes stack.
