Why do you want to change the Number ????.
You will need a cable if you are gonna use software from the net. but don't use wintesla, I don't know of any software from the net that will do this without killing the phone.
The best way I have found is to use an eprom programmer. I alway do it this way if customers insist on having the number changed,
but if it's just barred from the Orange network it will still work on all the others so just unlock it and use it on Vodaphone or swap it with somone on another network |
