You don't need the old device. Your subscription is linked to your Bunpo account, so log in on the new device with the same account and, if needed, use Profile > Settings > Restore purchase. See I upgraded my phone and want to continue my subscription.
However, restoring becomes impossible if you have also lost access to the account itself, for example the email address or inbox used to register the Bunpo account. For security reasons, we are unable to accommodate requests to manipulate user email addresses or passwords.
In these cases, automatic restoration of the subscription may not be possible, and a new subscription is necessary. We ask for your understanding.
