Does someone know how to change your nimber on a cell phone?

i want to be able to change my number so when i call someone i can make the number appear to be a different numberDoes someone know how to change your nimber on a cell phone?Its not possible...your phone number is stored on your SIM card, which isn't able to be altered. Your best bet is to use *67 before dialing the number so it shows as %26quot;private%26quot;
