I want to change my number - ZTE Cell Phones

Depends on who your cellphone service provider is. I only have experience with the Canadian cell phone providers. If you want to change your existing cell phone number permanently, call your service provider to change it for you. You can choose the area code, the first 3 digits of your phone number, or the last 4 digits of your phone number (depending on what your provider has available). For Canadian providers, there's usually a $20 fee per change.
