The SMS on the mobile phone is backed up in the cloud, and the cloud is gone after being deleted on the mobile phone.

This visual inspection should be that you have turned on the automatic backup of SMS.

That is, if your mobile phone changes, it will automatically back up the changes to the cloud.

It is equivalent to always backing up your mobile phone.

So after you delete the text messages on your mobile phone, the ones in the cloud will also be deleted.

You just turn off the automatic backup.

Or you can back it up to your computer.

Just use the pc version of the application software and connect it to the toolbox.

Just find the data backup. This backup is once and for all.

It will not overlap, and it is more convenient to manage. I hope it can be adopted.
