How to send a red rice mobile phone without a calling card, free online news.

This is a function that users who use MIUI system can use free network messages with each other. As long as it is a new machine or the MIUI system is started after three factory cleanings, you will be required to send a short message to the MIUI server to activate this network short message function. MIUI free SMS is a bit like Apple's FACETIME, and SMS between Apple's IOS is based on network traffic. The reason why the system requires users to send short messages for active activation can be understood as "I agree to open network short messages". In addition, you will be charged for sending this activation message. Please pay attention to this.

After activation, if the other party also uses miui system, turn on the free network short message function in the short message setting, and then turn on the data switch when sending the short message, so that the network short message can be sent for free at that time, and the "free network short message" will appear in the small box where the information is input.

I hope I can help you and take my answer. Thank you.
