The number that is displayed in the phone settings page is not my number. This is on a Nokia Lumia 620 running Windows Phone 8 (8.0.10211.204).

Where does the phone get this number from? Is there a way it can be changed? What are the implications of it being wrong?

    Out of curiosity, are you able to temporarily put another sim card into the phone and see what happens?

  • Yes, I can try this but I will have to wait until the weekend to get hold of another micro SIM. Apr 18, 2013 at 7:07

    Try it out and append to your question the results of doing so.

My phone is exactly the same and there is nothing you can do….

It usually happens when you want to keep your existing number and put it on a new SIM. In my case I went from a standard SIM to a Micro SIM.

As far as I’m aware there are no implications. It’s just the original number which the Phone has found on the card- before your settings were transferred.


Sign in to windowsphone.com with your authorized email account. Go to account settings and under your phone you need to update your new number.
