Call Protect is a free robocall blocker with Caller ID tool that safeguards you against known telemarketers, robo callers, scammers, spammers, and other unwanted callers. With Call Protect, you can have a peace of mind whilst it silently works for you to reduce the number of unsolicited phone calls you receive. Call Protect maintains the latest database of active spam and robo callers. This list is monitored and updated in real-time. When you activate the Call Protect extension, the list of suspicious phone numbers is periodically updated onto your device. The highly-risky phone numbers that have been identified as harmful with our sophisticated algorithms are automatically blocked; while the other numbers, which may potentially be harmful, but have not been identified as such with full confidence yet, are added onto your phone with their caller ID information containing a warning message. This will alert you when you receive a phone call from such suspicious callers. These features work alongside each other to protect you against ever-evolving spammers. Beside Call Blocking and automatic Caller ID, this app also has a Caller ID lookup feature. You may use this feature to perform a reverse phone number lookup for free on any phone number from the US and Canada.
