What does CRBT mean or stand for ?
We all know what CRBT is but we do not know it as that name.We all all it as a caller tune,you know that peppy song or lyrics that you hear when you call your friend and wait for him/her to pickup.Instead of hearing the “beep beep” the receiver can hear a customized song.
There are many apps and websites that allow you to download,set and choose a ringtone of your choice and this will play for everyone that calls you.
