If you have an Android phone, you may have noticed when you turned on Filter Spam Calls that there's another option immediately below it, called Verified Calls.

Here, you can block categories like international calls, roaming calls, or all incoming calls. There’s also an option for fixed dialling numbers, which lets you whitelist only certain contacts.

Android has a similar setting that allows you to block calls from private or unidentified numbers, although you will still receive calls from numbers that aren’t stored in your contact list.

Tired of scam calls? NordVPN’s Android app now screens them for free – here’s why I think it’s a big win for subscribers.
