Why can I not set up my voicemail on my iPhone?

Answer: A: You don’t setup voicemail yourself on the phone. Voicemail is a carrier feature, and they are the ones that set it up. The carrier decides if they support visual voicemail, or standard voicemail, and your account has to be provisioned by the carrier for it.
