Number blocking how to i stop a number from calling me on my samsung tocco lite, i want to block it?

I think you can have a try with LEO Privacy. It can help you completely block spam phones, and many other features to secure mobile.

Go to the call register, touch the number you want to block. On the bottom right you will see the MORE tab. Touch that and the option to add the number to reject list will be found. Hit it and there you go, number automatically rejected

You cannot stop somebody calling your number. But you can configure your in such a way that you will not get the notification like ringing or vibration when they call you. For that, goto call log and select the number-->select-->Add to reject list....
thats it.
