Question

I got a call from a prank caller, on my mobile how can i see their number?

Answer 1

if they use *67 before the number....then there is no way!!! but you can use*77 ACR so they can call in without leaving there number!!

Answer 2

If this is a cellular phone it can't be done.   THe call that originates goes through the network of your carrier and it is being blocked before the call reaches their network.  The best thing to do is change your number.   If its with AT&T they will change it w/o a fee if you request them to do so ( provided you pay your bill on time).  Most carriers charge $36.00 to make this change.
