Hello
I have been using Truecaller app since one year. I found it very informative. Actually I installed this app to know about the unsaved phone number identity. It is working very good in indentifying phone numbers. It is very beneficial for the number which come through companies because they deduct balance to receive them. In these circumstances this app help me a lot. I highly recommend to other people if they are searching for this type of app. It is awsome product, use it .
Thank you
Have a nice day
