10658112210002 SMS

When I came back from abroad last month, I found more than a dozen international short messages, each 1. 19 yuan, half of which were106581221002, and 447537410287,992. They insisted that it was sent automatically by the mobile phone. At first, it was said that it was sent automatically by a smartphone. Later, it was said that the mainland version of Apple's mobile phone would happen abroad. I told me that it was the American version of the mobile phone, and the customer service said that this would happen when using the American version of the mobile phone in mainland China. This is sheer nonsense! Now the money has been withheld, but how can we stop it in the future?
