If you changed to a device with the same OS (e.g. two iPhones, two Android devices), your LINE Stickers Premium information will also be transferred by transferring your LINE account.
If you change to a device with a different OS (iPhone to Android or vice versa), you need to change your subscription if you want to continue using LINE Stickers Premium.
You will not be able to change or update your plan from within the LINE app if the device you're currently using runs on a different OS than the one you used to subscribe to the plan. If you can use the Apple ID or Google account you subscribed to your plan with, see the following page for your device to cancel your subscription, then purchase a plan on your new device.
If you used an iPhone:
If you want to cancel a subscription from Apple
If you used an Android device:
