The mobile phone watch received many verification code messages. What happened?

It may be that someone bombarded your mobile phone with text messages with software, or that you accidentally leaked your mobile phone number in other places, resulting in a large number of advertising text messages. I suggest you check whether automatic interception is set.

Turning on automatic interception can filter some short messages, but it can't solve the problem from the root. It's best not to disclose your mobile phone number.
