Nokia Lumia 822 - What happens to any credit or subscriptions I have with MixRadio if I update my Nokia Account country settings?

If you update your country settings for your Nokia Account, you will no longer have access to any MixRadio credit or MixRadio+ subscriptions belonging to the original country. To regain access you will need to change back again. 

Note that you may continue to get charged for any MixRadio+ subscriptions you have unless you cancel them before updating your country settings. You can go back and change your settings back to the original country.
