As long as you have an existing valid subscription on one device, a second device can access this same subscription plan.
Perform a MySudo VPN account import/export transfer via QR code scan from one device to the other. Once the transfer is complete, the two devices will share the same account and the same subscription plan.
If you cancel the subscription on the first device, you will need to re-subscribe on the second device so you don’t miss out on all the benefits of a subscription plan.
For example, if you have a subscription for MySudo VPN on iOS, and then you do a QR code transfer to an Android device, the Android device will share the same subscription plan as the iOS device. If you stop using MySudo VPN on iOS, cancel the subscription with the Apple App Store and re-subscribe in the Google Play Store so you can continue using the same plan.
Note: If your subscription has expired, you can’t restore it on another device. You will need to purchase a new subscription.
