If you have installed the Ultima Farm app on your new smartphone and want to continue using your farm, you can restore it with a private key.

After authorization in the app and creating a PIN code, select "WITH PRIVATE KEY AND T-PIN"  as the import method.

This will bring up a screen to enter your private key or scan its QR code. Make sure you have inserted the key correctly and then click on "ОК":

The next screen will prompt you to enter your transport PIN. Enter it and then click on "ОК":
