How to cancel the stock SMS notification and telephone call of CBN?

If the service is not subscribed by the mobile communication service provider, it is usually difficult to cancel the service. My approach is: install 360 mobile guards, directly blacklist frequently received text messages and phone numbers, and refuse to receive them. If you have time, just remember to enter the software to clear it. As for the way to complain about something, you can try it if you are bored, but personally, it doesn't help much.

I hope you will get out of trouble as soon as possible.
