We recently changed my wife's mobile over from a Vodafone pre-paid chip to a Telstra pre-paid chip. She ported over her number, and eveyone has been able to contact her on that number. Except me. I'm on a Vodafone Cap plan, and when I ring her I get a message which says "number not in use". It doesn't even try and ring it. We can ring her from my daughter's "3" phone, from the land-line, from anywhere in the known universe, just not from my Vodafone mobile. And, of course, top of the list of numbers that I'm likely to call, ...... is her number :roll:.
