  • 😂 scams in Ottawa market place FB, pay attention to the email that I provided
    Hiya.com - it comes default with most Samsung phones. Otherwise, you have to download it. It compares the incoming call and SMS telephone numbers against a database of known scammers, spammers and fraudsters. You can set it to auto block... Source: about 4 years ago
  • How to have my name show on all other phones I call?
    It turns out it's via a service called Hiya. Haven't looked fully into how you go about adding your name and phone number to that, but obviously it would only work on compatible phones. Source: almost 5 years ago
  • Already got three calls today.... all local numbers
    But you're right - most of the time it's a local number (even though it really isn't)! You can get the hiya.com app, which is really helpful. Source: over 5 years ago
