How to hack each other's short messages

How to blackmail the other party by SMS:

1. For Apple phones, first turn on the phone, find the setting options from the phone desktop and turn them on. After entering the settings page, find the information option. After opening, find the blacklist. Click Add in the blacklist page and enter the number to be blacklisted. So you won't receive any news from this number.

2. For some Android phones, the black screen only plays the function of harassment interception, and the other party's short message will still be received, but it will be displayed in the interception message and will not receive the message prompt.
