Why Get an eSIM for Mongolia?
- Online from Ulaanbaatar Airport, ready for a ride, a transfer, or your rental car.
- Coordinate with drivers and tour guides, who often share plans by phone.
- Keep your number for bank codes and messages from home.
- Avoid expensive roaming with most home carriers.
How to Choose a Mongolia eSIM
Trip length
Pick a plan that covers your whole stay plus a spare day for flight times. egoViet plans can't be topped up, so it is better to size up than to run short. If your high-speed data does run out, you stay online at a basic speed of around 128 kbps, enough for messaging.
How much data you use
Maps and messages use little data. Uploading landscape videos uses much more. Here is a guide to how much data you need when you travel.
