How to find Mobile Service Provider?

    Hi , I've free calls to O2 phones in my inclusive minutes.
    But how can we verify if a particular phone number is with O2? since number porting is thr, we can't make use of first 4 digits too
    Is there any website or link to check a particular number belongs to O2 or other networks..?


    With number porting you can't tell any more what number is with which network.
    There was a range that each network had, but there's no way to tell if the number was ever ported to another network . . .

    Why don;t you just ask the person!
