ドコモデータコピー

■ App overview
Docomo Data Copy makes data migration easy and speedy when changing models! Since it is a one-to-one direct connection, you can rest assured that you do not have to worry about the amount of communication even with a large amount of data. Furthermore, back up important data to an SD card in case of emergency! We recommend that you regularly back up necessary data such as phonebooks and images in case your smartphone breaks down or you accidentally delete data.

■ Target data
・ Direct data migration
Phonebook / media (images / videos / music)
・ Backup and restore (SD card)
Phonebook / media (images / videos / music) / call history

* Supported functions and data items differ depending on the model and OS.

■ Notes
･ When migrating data, make sure that the latest docomo Data Copy application is installed on both the migration source and migration destination terminals.
･ When migrating data on iPhone / iPad, disable the synchronization settings such as iCloud in advance.
