I bought a new phone this one from Apple, before that I had a Huawei. Now I would like to lose the CHATverläufe but not when I insert the Sim card in the new phone. Does anyone have ideas or experiences like they are not lost?
Can make a backup before the settings
Create a backup on the old device and upload it to a cloud.
Apple Backup on iCloud and Android on Google Drive. You can download the backup again with a new phone. But that does not work from Apple to Android and vice versa.
