Hello,
I want to develop a program or web site such that when the user enters the country code and his/her mobile phone number, the program/web site will display the mobile operator accurately. How can I do that? I want the result to be correct even for phone numbers that have been ported between operators.
Thanks.

The only way I can think of that this could work is almost certainly impractical. That would be to have the network operators (all of them) allow you to check whether a given number is currently under their control. I can't believe for a second that they will allow this. They know the numbers in their network, but they are very unlikely to let any external agency see them.
One solution that I found:
Refer to a phone number list, like http://www.visualtron.com/

This can't be done, specifically for the reason you've mentioned in your last sentence. If a number can be valid across several networks, then there is, by definition, no way to determine what network that number is on.
