Or you can do the following:

  1. Tap the phone icon on your Android, which is usually at the bottom of the home screen.

  2. Tap the three dots at the top of the Phone app screen.

  3. Tap “Settings” in the dropdown menu.

  4. Tap “Block numbers” and then toggle the button beside “Block unknown callers” to green.

  5. Enjoy peace of mind!

Hi @Cedro - thank you for the tip. However, the method you have mentioned does not block calls from all unknown numbers (not in your contacts). Goal of this article is to block calls from anyone who is not in Contacts.

Your approach only blocks calls that are unknown in nature (caller id missing maybe). Here is some information about the default Phone app and Block unknown calls - Block or unblock a phone number - Phone app Help

That’s weird, because that’s not what it says on my phone

Usually “unidentified callers” refers to callers that have declined or blocked their CallerID from being sent. These usually show up as “Unknown Caller” or similar, depending upon the Dialer app.

The functionality in Simple Mobile Tools Dialer is more akin to a FDN (but working in the other direction) from older GSM/SIM phones where you could store a fixed allow-list of numbers on the SIM (password-protected) that prevented the phone from dialing out to anything but those.

On Simple Mobile Tools Dialer, enabling the restricted mode prevents any phone call not stored in your Contacts list, which would include things like Blocked numbers and Unknown Callers, so it is even more restrictive than Google’s Dialer.

So with this, you can setup a really limited Contacts list of say Home phone, Mom, Dad, School, etc, and nothing inbound or outbound will connect that is not in that list of Contacts.

Have followed installation directions for simple mobile tools but app doesn’t restrict inbound and outbound calls to contacts list.

Inbound numbers not on contact list go to voicemail. Outbound numbers not on contact list still allow outbound calls to those numbers.

Welcome!

It sounds like using the FDN function might be more what you want.

Have you looked into that?

Hi @Flashcoach - thanks for the feedback. It seems their feature set might be incomplete.
