Hello! Let me ask you, how to send text messages to Mongolia with China mobile phone? Thank you.

The international area code of Mongolia is 976, and the number you sent should be 00976 plus the local mobile phone number. If you want to send a message to China people who are going to Mongolia, you can send it directly. If you are in Mongolia, send a text message to a domestic mobile phone and write 0086 in front of the mobile phone number.
