Change a currently valid subscription plan

Q: I have a valid subscription, but now I want to upgrade to Premium / Pro / Elite Plan. Or I want to downgrade to Basic? What should I do?

A: You can covert your current plan’s remaining data and days to credit and resubscribe another plan using this credit. This can be done here:

User Center => Payments => Subscription Record.

On the Payment page, you can scroll down to the bottom of the page, and there you can find a Subscription Record tab and at the end of tab, there is a button to convert your current plan to credit.

Once you have converted, you can go subscribe another plan with the credit you have.
