Why do I receive text messages from other communities?

1. Others filled in the wrong contact phone number, resulting in a text message being sent to you.

2. If other people’s affairs involve your affairs, they will send you messages. You can call for consultation.

Because the devices are all logged in with the same appleid in icloud. You can click Settings-icloud-to turn off the document and data functions inside. If there is data that you don’t want to share, you can also turn off the switch separately.

Or if there is a device that is no longer needed, log out of the iCloud account directly, or log in to another Apple ID account.
