Hello! I see you’re having trouble with payment in the Дед ВПН app on your iPhone running iOS 18.7. Let’s figure this out together.

To help you better, could you please tell me:
- Are you trying to pay through the App Store or directly inside the Дед ВПН app?
- What exactly happens when you try to complete the payment? Any error messages or failed transaction notes?
- Have you already tried anything like restarting the app or your phone?

Once I have these details, I can guide you step-by-step on how to fix it. Meanwhile, here are some common fixes for payment issues on iPhone:

1. Check Your Apple ID Payment Method:
- Go to Settings > [your name] > Payment & Shipping.
- Confirm that your payment method is valid and up to date.

2. Sign Out and Back Into Your Apple ID:
- Open Settings > [your name] > Sign Out.
- Sign in again with your Apple credentials, then try payment.

3. Restart Your iPhone:
- Hold the side button and volume button, then slide to power off.
- Turn the device back on and try again.

4. Ensure App Store Region Matches Your Payment Method:
- Go to Settings > [your name] > Media & Purchases > View Account > Country/Region.
- Make sure your region is correct and matches your payment information.

5. Update the Дед ВПН app to the latest version from the App Store.

If payment is done inside the Дед ВПН app via a non-App Store gateway, check:
- Internet connection stability.
- If the app has any built-in error messages or instructions on payment failure steps.

Please let me know what you’ve tried or what error you see. This will help me provide more tailored advice!
