If your old phone is a Windows Phone, the easiest way to transfer your contacts, calendar, and text messages to your new Nokia Lumia is your Microsoft account.

If you don't have a Microsoft account set up on your new Nokia Lumia yet, on the start screen, swipe down from the top of the screen, tap ALL SETTINGS > email+‎accounts > add an account, and create a Microsoft account following the instructions shown on the screen.

  1. To select what you want to back up to your Microsoft account, on your previous Windows Phone device, on the start screen, swipe left, and tap settings iconSettings > backup.

    Your contacts and calendar are backed up automatically to your Microsoft account.

  2. On your new Nokia Lumia, sign in to your Microsoft account. Your contacts, calendar, and text messages are automatically transferred to your new Nokia Lumia.
