I am also trying to change my number as I wish to port my current number to another network due to better coverage. I wish to keep my Three account as a secondary one for at least the remainder of my 'in contract' period as I have to pay anyway. They tell me they can't do it but I know they can as I've done something similar in the past with another network when I changed. No skin off their nose, they get paid anyway. Not sure what to do to get them to do something so simple as changing the number.
