    I just bought a new Nokia Lumia on O2 Pay & Go. After inserting the new SIM i decided to retain my old number and got O2 to update the SIM. I notice however that the "My Number" setting in the Phone Settings section of the Lumia that it still shows the number that was supplied with the new SIM and there does not appear any way to edit this, can anyone help?

    I'm pretty sure you can't, as I have the same issue on my 930 and my wifes 630.
    the best you can do is go here:
    https://www.windowsphone.com/en-gb/my/account
    then click on 'update' next to your phone, and you can enter your new number in there.

    However, the phone reads the 'MDN' which seems to be hardcoded to the physical sim - this is frustratingly what is also used in the windowsphone app.

    I recall reading that you can get O2 to send you a replacement sim with the correct MDN, then the number will appear correct in all locations
