Frequently asked questions
Do I need an account?
No. DenyCalls works with a permanent device code only — no logins, no user accounts.
Where do I find the device code?
The device code is shown in the DenyCalls app on the phone that should be protected.
Can someone else pay for my device?
Yes. A parent, child or relative can enter the device code here and pay for the device.
Will approved numbers still get through?
Yes. Approved contacts ring exactly as before. Only unknown numbers are blocked.
