Hi here is how to change"my number" on a TELUS STORM 9530
Go to your phone key pad and type ##843881 a screen will come up that says" CDMA service edit screen",where it says" mobile directory number" you will see the old number you want to get rid of high light it and type in your 10 digit phone number then press the blackberry menu dingleberry and save what you have done. Go back to the main phone Page and you should see your number under the "my number". It worked for me I hope you have success too best of luck
