If you change your device, you can transfer your premium pass benefits (subscription) and items at no additional cost by following these steps:
1. On your old device, link your premium pass subscription save data to your account.
Please see I want to link an account to Pokémon Trading Card Game Pocket. on how to link accounts.
2. On your new device, activate the Apple Account or Google Account with which you subscribed to the premium pass.
3. Link your new device with the account linked in step 1.
4. Tap Complete Purchase on the Premium Pass screen.
Changing platform accounts for automatic renewal
1. If your new device uses a different OS than your previous device (from iOS to Android or Android to iOS), your premium pass benefits and items will transfer, but automatic renewals will be charged to the platform account of your old device.
2. If you want to change your platform account for automatic renewals, please cancel your premium pass subscription with the platform account of your old device.
Note: If you try to cancel your premium pass subscription with your new device from the “Tap here to cancel subscription” option in-game, you may be redirected to the subscriptions screen of a platform different from the one you used to subscribe to the premium pass with.
Example: You changed to an Android, but your old device was an iOS device, so your premium pass subscription is with Apple’s App Store. You transfer your save data to the Android device and tap “Tap here to cancel subscription”, which may redirect you to Google Play’s subscriptions screen instead of Apple’s App Store where you are subscribed to the premium pass. In such cases, you would need to cancel your subscription by logging into Apple’s App Store from your old device or browser using your Apple Account with which you subscribed to the premium pass.
3. Once your premium pass expires, you can subscribe to it again using the platform account of your new device.
