Two iPhone5s phones, one for texting and the other for displaying. What's going on?

This is logging into the same icloud account, and both devices can send and receive text messages.

First, the solution to the problem.

Turn off iCloud cloud synchronization in settings.

One of the devices was replaced with a new iCloud account.

Turn off iCloud cloud synchronization settings and electrical equipment settings -iCloud, and turn off the option of synchronizing information in iCloud, so that the information in iCloud will not be uploaded or downloaded synchronously.

Changing a new iCloud account will also prevent the same information from synchronizing with each other.
