We are in the process of developing our own “Safe calling” feature where the parents will be able to allow/block contacts and all unknown calls will be blocked. The current ETA to launch is 4-6 weeks (mid-July 2023). Till that time, you can use the workaround mentioned in this article.
The default phone dialing app on Teracube Thrive is the “Google Phone” app. While it has pretty good anti-spam features, one feature it does not have is to block all unknown calls.
Warning: Once you block all unknown calls, your child may not receive calls from emergency services like Police calls. Also - you may not be able to reach your child from other phones (if you do not have access to your own phone).
Note: As noted by @Flashcoach - this process will only limit incoming calls.
If you would like to block all unknown calls (callers who are not in your contacts), then please do the following (3rd party app - costs $1.59):
On the Thrive phone, Install the “Simple Dialer” app from Play store.
Open the Simple Dialer app. Make it the default calling app when asked for.
Tap the 3-dots on top-right > Settings > Manage Blocked Numbers (Locked)
Pay $1.59 to get their paid feature
Once you have paid (installed their paid thank you app), open Simple Dialer > 3-dot menu > Settings > Manage Blocked Numbers
Check the setting at the top “Block calls from not stored contacts”. The app will guide you to make it the default Spam handling app.
Remove the shortcut for the old phone app from home screen. Drag the Simple Dialer to your homescreen so that your kid uses simple dialer all the time.
You should be all set now. All unknown calls will get blocked.
We are working on implementing this as a built-in feature in Thrive in the near future.
