I get two text messages every three days.

1. If it is a smart phone, you can download some auxiliary software. There are many mobile phone housekeepers on the Internet. Many mobile phones have their own harassment interception, and mobile phone short messages have blacklist options. Add unwanted numbers to the blacklist and block them automatically in the future.

2. You can consult the manual station 10086 and ask the manual station to cancel some mobile newspapers, which will secretly deduct money.

For reference!
