What you get with Yesim in Mongolia

Set up before you fly
Buy in the Yesim app and install your QR code at home. Your plan activates automatically when you first connect to a local tower in Mongolia.
📱
Keep your existing number
Yesim runs as a second line alongside your home SIM. Your usual number stays active for calls and texts — Yesim handles data only.
🔥
Hotspot included
All Yesim Mongolia plans include hotspot sharing, so you can connect a laptop or tablet from the same data allowance with no extra fee.
📊
Real-time data usage
Track exactly how much data you've used at any time in the Yesim app, so you never get caught short before your next refill.
☎️
Travel beyond Mongolia
If your Mongolia trip is part of a wider journey, Yesim covers many other destinations from the same app — manage everything in one place.
📅
Flexible up to 30 days
Yesim Mongolia plans run up to 30 days from first use. Buy in advance so you're ready the moment you land.

Which Yesim plan should you pick?

For a short city break of 3–5 days, the cheapest plan at £4.39 will cover Maps, WhatsApp, and casual browsing. If you're spending one to two weeks travelling around Mongolia, step up to a mid-tier plan — usually the strongest value option on a per-GB basis in Yesim's Mongolia lineup.

If you plan to work remotely, stream video daily, or use your phone as a hotspot for a laptop, lean towards a larger bundle — the 10 GB option is the safer choice. The unlimited plans are priced at a premium but make sense for heavy users who don't want to track usage.

One thing to note: Yesim Mongolia plans are data-only. You won't get a local number, but your existing SIM handles calls and texts as normal. iMessage, WhatsApp, and FaceTime all work over data.

Yesim eSIM for Mongolia 2026 — what you need to know

Yesim is a well-regarded eSIM provider with solid Mongolia coverage. Plans range from short-break options to longer-stay packages, making Yesim a flexible choice whether you're spending a long weekend or travelling for a month.

Mongolia has four operators: Mobicom (the biggest, the incumbent), Unitel, Skytel and G-Mobile. Mobicom and Unitel both have 4G across Ulaanbaatar and most provincial capitals, and 5G has launched commercially in Ulaanbaatar. The big challenge here is the country itself, it's massive and mostly empty. Coverage exists along the main roads and in the soum (district) centres but the steppe in between is largely off-grid. The Gobi Desert tours, the Khövsgöl Lake area and the Altai mountains have signal in towns and at some ger camps but expect long stretches of nothing. Local guides usually carry sat phones for serious trips.

Is Yesim good in Mongolia?

In our testing, Yesim connected reliably across major cities and travel routes in Mongolia. Plug is type C/E (230V) and the currency is the tögrög. Ulaanbaatar gets seriously cold in winter (down to minus 30s), and air pollution in the city is among the worst in the world from December to February.
