I have had the same mobile phone number for about 15 years and would like to keep it forever. So does number portability mean that you can move your 021 number from Vodafone to 2 degrees, and back again if it doesn't work out with 2 degrees?
Does number portability rely on goodwill from the telco, or is it a neutral, accepted way of doing things between telcos?
By number portabilty I mean keeping the 021 part of the number as well.
