Any recommendation for apps that actually block spam calls? I've tried Hiya and CallerSmart with little to no success. I would block all incoming calls except contacts, but I can't do this since I use my phone for business calls.

Also interested in something like this. I am not a tech saavy guy though.

Was looking around at services offered by a company called Cloaked. Services offered included below. Not really sure if this is any good or what. $140 for the year for my wife and I.
Mobile VPN
Data removal & dark web monitoring
Unlimited aliases & password manager
Call Guard instant spam protection
$1 million identity theft insurance
Call, text and email in one place
Custom password manager fields
2FA login support
Identity sharing
One-on-one customer support

No. There is no way, only partial methods, but they get around them in various ways.
