Why do some strange numbers from other places always call me?

Many strange numbers are fraudulent phone calls, and there are many ways for personal phone numbers to be leaked, such as handling credit cards, SMS notification of utilities, etc. Individuals will disclose customer information to fraudulent companies to obtain illegal income. It is suggested that you install a phone interception software on your mobile phone, such as "incoming call". Fraudulent calls reported or identified by many people will be automatically intercepted, which can reduce unnecessary interference.
