Someone received a short message with a number.

No, I suggest you change your new mobile phone number immediately.

1. If you are already bound to this unused mobile phone number, such as Alipay account, I suggest you change the new mobile phone number you are using immediately. Then the old mobile phone number can't be published on your account.

Your information should not be leaked. I have two unused mobile phone numbers, and I have bound some accounts before. I didn't find anything unusual.
