Mobile data for Mongolia, delivered by email, plus the 30-day Trip Assistant — practical local guidance for getting around, staying connected, and staying safe. It's included with every plan, whichever one you choose.

Standard plans give you one set amount of data to use throughout your plan. For example, 5GB for 30 days. They offer better value per GB and are a good choice if you know roughly how much data you'll need.

Daily plans give you a fresh amount of data every 24 hours. For example, 1GB every day for 7 days. They're ideal if you want a reliable amount of data available each day.

In short: Choose Standard for better value and flexible usage. Choose Daily when you want fresh data every day.

Both include the same 30-day Trip Assistant.

Practical, bite-sized guidance included with every eSIM for 30 days — quick answers for common situations while you're traveling, from getting connected and getting around to handling money, local customs, and staying safe.

Built for on-the-go use, so you can find what you need in seconds instead of digging through a long travel guide.

Ulaanbaatar, Erdenet, and Darkhan have strong coverage, and aimag (provincial) centers are strong too. Our eSIMs run on Mongolia's largest mobile network, but remote countryside coverage still varies — some areas are well covered, while others have limited or no signal simply because of how vast and sparsely populated Mongolia is. See our mobile coverage guide for details and what to do if you lose signal.

This is usually caused by one of three things: your Mongolia eSIM line is turned off, it isn't selected for Cellular (or Mobile) Data, or Data Roaming is off for the eSIM. First, make sure the Mongolia eSIM line is turned on, then select it for mobile data and turn on Data Roaming — see the exact steps for your phone.

Already done all three? Give it a minute or two. Still nothing? Turn Airplane Mode on for about 10 seconds, then turn it off again. This forces your phone to re-register with the network.

If you're using the Trip Assistant, tap the Check your usage link in the top row.

You can also check your phone’s built-in mobile data usage in Settings, although the menu and usage information vary by phone and OS.

Nothing is charged and no plan is created — just try again whenever you're ready.
