Apple's mobile phone always receives a lot of advertising messages. How to turn it off?

Closing mode: Settings-Notification-Message. Set the "Repeat Reminder" to "Never", and the messages you receive in the future will only ring once.

Do you feel that the advertisements recommended by iPhone are particularly targeted? As soon as I arrived at a place on May 1, I received all kinds of strange hotel advertisements. In fact, this is the advertisement tracking function of iPhone, which can display more targeted advertisements according to the user's location, content and usage habits. The setting mode is Settings-Privacy-Advertising, and "Restrict Advertising Tracking" is turned on.
