Is there a charge for mainland users of China Mobile roaming to send messages to 10086? Or is it free?

Hello, call 10086 when the mobile phone number roams to Hong Kong. The normal charge is based on the charge for sending Chinese mainland number when roaming to Hong Kong. If you are the number of Beijing Mobile, and you are a GSM, M-Zone or 5 yuan card, you can send 10086 short messages in Hong Kong, with a charge of 0.39 yuan each; If you are an upgraded standard card, listening card or home card of China Bank, you can send 10086 short messages in Hong Kong at a charge of 0.44 yuan each. Thank you for your support to China Mobile, and wish you a happy life!
