Why can't my mobile phone number receive the SMS verification code of individual apps?

If it's not a terminal problem, it's usually that you send their SP an unsubscribe instruction similar to' 0000', such as 1065xxxx, and they are not allowed to send you a short message, otherwise they will be investigated for violation. This instruction is very depressing for rejecting spam messages sent by SP (this problem is not serious in recent years, especially SP), but it is not easy to receive verification code.

The solution is to look at their short message number, 106 xxxxx, and then guess their special service number, which is the prefix of the short message number. Yes, I guessed, because no one knows whether it is 8 digits or 1 1 digits, but it is a prefix anyway, and it is sent to 1 165438+.
