TrueCaller is supported by more than 100 devices and runs in the background and activates on incoming phone calls and text messages (SMS).
This is how TrueCaller works
- You receive a phone call from a number that is not saved in your phone book
- TrueCaller searches for the number in our databases
- If TrueCaller finds the number it will be displayed on your screen. If number is not found you will be prompted, "No matches found..."
- When phone call has ended TrueCaller will ask you if you want to save the caller to your phone book (if the caller is found)
