After changing devices I can't use LINE on my previous device. toggle
If you register to LINE using the same phone number or email address as you did on the previous device, the LINE account on the previous device will be automatically deleted, and you will not be able to start LINE on that device.

We are sorry to say that if you have already verified your account on the new device, there is no way to recover the previous account.

*If you want to use LINE on multiple devices, you will need a different phone number for each device.
