Provide SMS for mobile phone activities.

As long as it is 10086, promotional messages are credible. Judging from the short message, this is an activity made by Xiamen Mobile to expand its customer base.

In order to avoid your worries, it is suggested that you dial 10086 and press the 0 key to check the brand of mobile phone and the way to give away the phone bill, and then go to the local mobile communication service hall 100 to participate in the activities.

I hope I can help you!
