Belgium already has mobile number portability (Score 1)

If I recall correctly, it began in belgium 01/01/2003. Unfortunately, prices are sometimes higher when calling to another mobile network, and because we now can't see anymore by the number which network we are calling to, we have no certain idea of the price of our call. There is a number where you can request the provider for a certain phone number, but this is a serious hassle ofcourse.
