No scope of error
If you want to find out who prank called you, then there are various ways to find so. You can simply type in the number on any search engine or consult government directories or yellow pages. Out here chances are very rare that you will get information about the number and especially mobile numbers. In this case spend a little money and hire paid private reverse phone lookup services. Their information is reliable as well as latest. These lookup services are in collaboration with different phone companies and thus have access to all their databases. So you see there is not a slightest scope of error in it.
