How to block iPhone number
Blocking numbers on iPhone is simple, and there are several ways to operate:

- Block via call history : Open the Phone app, find the number you want to block, click the "i" icon on the right, and select "Block this caller". This not only blocks the phone, but also filters out text messages and FaceTime for this number.
- Blocking through information : If harassment comes from a text message, you can click on the conversation in the message, click the number at the top, and then enter the details page to block it.
- Unified management in settings : Go to "Settings> Phone/Information/FaceTime", you can see the list of blocked numbers, or add new numbers here.
Note: When you call the number you blocked, you will be hung up silently, and the other party will not know that you have blocked him.
How to block numbers on Android phones
Because there are more brands of Android, the operations of different manufacturers are slightly different, but the general process is similar:

- Use the built-in functions of the phone app : Open the phone app, enter "Recent Calls" or "Contacts", press and hold the number you want to block, and select "Block" or "Add to Blacklist".
- SMS can also be blocked : open harassment text messages in the message application, click the menu in the upper right corner, and select "Block contacts" or similar options.
- Third-party application assistance : If you feel that the native functions are not enough, you can use applications such as Truecaller and Blacklist to enhance interception capabilities and identify unfamiliar calls.
Some Android phones also support the settings of "automatic rejection" and "no notification", which can be adjusted according to your needs.
Some things to note
Although blocking numbers may seem simple, there are several details that are easily overlooked:
- The blocked history will not be deleted automatically, you need to clean it manually.
- If the other party changes the number and continues to harass you, you may need to update your blacklist regularly.
- Some old models or low-end Androids may have incomplete blocking functions. It is recommended to upgrade the system or use security apps.
- When roaming abroad, the blocking function may be limited, depending on the support status of the local operator.
In addition, some operators also provide paid anti-harassment services, which are suitable for people who often receive sales calls.
Basically these are the operations. It's not particularly complicated, but sometimes when you really encounter annoying numbers, setting up a block in advance can really save you a lot of trouble.
