Does TickTalk block calls and messages from strangers?

Yes, TickTalk 4 can block calls and messages from unknown numbers, allowing only parent-approved contacts to contact the watch directly. To activate this feature, you will need to enable the Firewall through the free TickTalk App. Once you've turned on your smartwatch, which we suggest you do as soon as you've added in your Phone Book Contacts, no unknown callers will be able to contact your child.
