After brushing the mobile phone, Unicom has a lot of spam messages. Did they send it through the internet or by number?

This should be sent by the internet. You can install a Tencent mobile phone housekeeper to intercept it. It can intelligently identify received harassing calls and spam messages, and intercept them according to the number. In addition, it also has a unique information reporting function. If you receive harassing calls and spam, you can report them directly through the housekeeper's one-click method, and you can also blacklist all the numbers that have sent text messages and incoming calls, so as to prevent these numbers from calling and texting again.
