Is it possible to change the phone number that is stored on the sim card using a WP7 Phone (specifically the Nokia Lumia 800). I know its possible with some android phones.
Reasoning behind this is that I transferred old number to a new sim, but the sim card still shows the old number. The mobile carrier (orange UK) tried and failed to change it.
I have got a replacement fixed Sim now, but was wondering WP7 is capable of this?
