How to restore txt format SMS backup for Android phone

It can be realized by software backup, taking QQ synchronization assistant as an example. Download the Android version of QQ synchronization assistant on the mobile phone that needs to be backed up, install it, enter the synchronization assistant, find the SMS backup, log in to QQ number, and synchronize the SMS content to the cloud. Open another Android phone, download QQ synchronization assistant, log in to the same QQ number, and you can synchronize SMS from the cloud to this phone. Other backup software is similar. The basic principle is to back up the data to the cloud first, and then restore the data through the cloud on the new mobile phone.
