Can I upgrade or downgrade my plan at anytime?
Yes, of course. Although you're able to upgrade at any time, downgrading will mean losing certain features. If you choose to downgrade, you will disable those features before the downgrade occur. Also, anything you've pre-paid for can neither be refunded nor credited to your account.
