Truecaller is a good application and I really like this application because this application verified the phone number and all the phone number which are coming from the other side which you don’t know on which is don’t save on your contact list they can verify them and know the name but I think for verification and security of person and the interface of the application is also very good the app is user friendly and but one thing and one disadvantage of this app is that you have to only free jio for G Internet then you can verify the number into Zinta and you cannot verify the number only three G 4th gen WiFi can WiFi the number so it is the disadvantage of this app because if you are out of the home and if you have a 2G Internet I don’t have Internet so you cannot verify the number you want it is necessary to connect the Internet when you can verify the number the switch on the function of this app is awesome and it is very good for everyone who are new in this app you can also know the everything because the interface and functions and features available of this app I don’t know about the service support of the Truecaller because I don’t try the service of the Truecaller but according to the app services also good according to me personally.!
