Mongolia eSIM vs Local SIM vs Carrier Billing
For Aussie travellers, a HelloRoam eSIM is generally the most cost-effective way to get data abroad compared to local SIM cards or Australian carrier roaming add-ons.
| Category | HelloRoam eSIM from A$8.18 Recommended | Mongolia local SIM: MNT 10,000 to 30,000 (AUD 3 to 9) | Home carrier international billing: AUD 10 to 20 per day |
|---|---|---|---|
| Typical cost | From A$8.52 total | A$4.26–A$12.78 total | A$14.20–A$28.39/day |
| Details | Buy before you leave. Activate in Ulaanbaatar instantly. No registration at a local shop. Works from the moment you land at Chinggis Khaan Airport. | Local SIMs from MobiCom or Unitel are affordable at Ulaanbaatar shops. Registration requires a passport. The process takes 15 to 30 minutes. Local SIMs give the same coverage footprint as eSIM plans in remote areas, since coverage limitations are geographic, not carrier-specific. | US and European carriers charge high daily fees for Mongolia data. Coverage quality in remote areas does not improve with roaming compared to local networks. A HelloRoam eSIM gives you flat-rate data for Ulaanbaatar and covered road corridors. |
Prices approximate as of . Actual savings vary.
Best Time to Visit Mongolia
June to August is the main travel season. Naadam Festival in July is a major event. Winter temperatures drop to -40°C.
Network demand is higher in peak tourist periods. A HelloRoam eSIM means you are not competing for crowded public Wi-Fi at popular spots.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
