Expansion,

First of all, connect the old mobile phone to the computer with a data cable, and connect it to the computer with a mobile assistant instead of wifi.

Open the mobile assistant, click on SMS, export all SMS, and select the export and storage location.

Disconnect the old mobile phone after successful export. Then connect the new mobile phone to the computer in the same way.

Open the mobile assistant and select "Import/Export" to import the SMS file we exported into the new mobile phone.

Import may take a long time due to the increase of file ratio. After waiting patiently, you can wait until the computer prompts you to import successfully.

Disconnect the new mobile phone from the computer. When we open the SMS on the mobile phone, we can find that the SMS in the old mobile phone has appeared in the new mobile phone one by one, and it's over!
