How to buy mobile phone data in Mongolia when it runs out?

You can add a data package with the operator of your mobile phone.

Take mobile phone users as an example. Download the China Mobile "Wuyouxing" APP. This is an outbound travel communication service portal APP launched by China Mobile for outbound travel users, allowing users to obtain city information when they are abroad. Features, discounted tickets, practical strategy information search, as well as services such as free overseas voice calls and preferential Internet traffic. Apply for a Belt and Road traffic package on the APP, and you can choose the duration.

Of course, there is another way to apply for a local phone card with your passport after arriving in Mongolia, which is much cheaper. Mongolian mobile phones use GSM or CDMA systems, and Mongolian cards can directly purchase 10,000 Mongolian card recharge data.
