Don't worry, it's a common mistake. Deleting the app cancels your access to your number, but it doesn't stop your subscription. To avoid future charges, you need to cancel your subscription directly through the App Store where you purchased it.
Here's how to cancel your subscription:
Open the App Store app on your iPhone or iPad.
Tap on your profile picture in the top right corner.
Select "Subscriptions".
Find the "2nd Phone Number" subscription and tap on it.
Tap "Cancel Subscription".
Important: You'll still be able to use your 2nd Phone Number and any remaining minutes or texts until the end of your current billing period. After that, your number will be deactivated, and you won't be charged again.
Here are some helpful tips:
If you're unsure which App Store account you used to buy the subscription, check your email receipts or contact Apple Support for help.
The 2nd Phone Number customer support team is also happy to assist you with any cancellation questions. Don't hesitate to reach out!
