To change subscription terms (for example, switching from 1 month to 6 months), you must first disable automatic renewal of the current plan and then sign up for a new one after the paid period expires.

In the App Store

1. Open the App Store application and tap the profile icon in the upper-right corner.
2. Go to Payments & Subscriptions.
3. Select NumBuster and tap Cancel Subscription.
4. After the current plan expires, go to the Paid Features section and subscribe for the desired period.

WEB Dashboard

1. Open app.numbuster.com in your browser and authorize with your account.
2. Go to Paid Features (wallet icon).
3. Click the Disable Renewal button. If the Payment Management button appears instead, click it and select Cancel Plan.
4. After the current plan expires, sign up for a new subscription in the Paid Features section.

Important: If you currently have an active paid period, there is no need to start a new subscription immediately. Wait until the current term ends before changing the type or period.
