It depends on the location. In Ulaanbaatar and major provincial centers (Aimag centers), you will have excellent 4G/LTE speeds. However, the Gobi Desert and the vast steppes are extremely remote. While our eSIM connects to the best available towers, signal can be intermittent or non-existent in deep desert areas (like the Khongor Sand Dunes). Most tourist Ger camps are located near signal towers, but we strongly recommend downloading offline maps before leaving the city.
Reliability is everything in Mongolia. Our eSIM connects to the country's leading providers, typically Unitel or Mobicom. These operators have the most extensive infrastructure across the country, giving you the best possible chance of staying connected whether you are at the Eagle Festival in Bayan-Ölgii or visiting Lake Khövsgöl.
This specific plan is valid only within Mongolia. The Trans-Mongolian Railway is a popular journey connecting Russia, Mongolia, and China. Once the train crosses the border into Russia (Siberia) or China (Inner Mongolia), your connection will stop. For this legendary train trip, we highly recommend checking our Asia Regional or Global eSIM plans to stay connected across all three countries.
Yes. GPS is essential for navigating Mongolia’s unmarked dirt tracks. Our eSIM allows you to use Google Maps or Maps.me. While you might lose signal in between destinations, having an active connection when you reach higher ground or settlements is crucial for safety and communication with your tour operator or rental agency.
Yes. Most traditional Ger camps do not have Wi-Fi, or it is very slow. Personal Hotspot (Tethering) is fully supported on our eSIM. This means you can turn your phone into a router and share your data with your laptop or friends inside your Ger to upload your starry night photos or check emails before sleep.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
No, Uber does not operate in Mongolia. You need reliable data to use UBCab, the most popular local taxi app, to get around Ulaanbaatar safely and avoid language barriers with drivers.
You will generally have strong signal in the gateway villages of Khatgal and Hankh, allowing you to share photos of the "Blue Pearl of Asia," but coverage drops significantly if you venture onto the water or remote shores.
Yes. Coverage is reliable at the massive Genghis Khan Equestrian Statue in Tsonjin Boldog, allowing you to live-stream the panoramic view from the observation deck on the horse's head.
Absolutely. If you are visiting in July for Naadam, reliable data is essential to check the real-time schedules for wrestling, archery, and horse racing events at the National Sports Stadium or Khui Doloon Khudag.
