Voicemail is a carrier service, not an iPhone feature. Your iPhone only displays what the carrier's voicemail platform delivers to it, so a message that never appears has usually failed on their side — an unprovisioned mailbox, a mailbox that was never set up with a greeting and password, or a full mailbox refusing new messages. The device-side causes are narrower: the voicemail number stored on the line pointing at the wrong platform, or a Visual Voicemail session that has not refreshed. On AT&T and T-Mobile you can read the stored number back with [*#5005*86#](/blog/check-your-voicemail-number-star-hash-5005-star-86-iphone/). A useful test is to call yourself from another phone, let it ring through, and leave a message. If the mailbox picks up and you still get nothing, the fault is in delivery rather than in the greeting or forwarding. ## What should I try, in order? - Press and hold 1 in the keypad, or dial *86, to call your mailbox. If it prompts you to set up a greeting and password, the mailbox was never initialised — do that now. - Have somebody call you and leave a message while you watch. If the call never rings, work through the straight-to-voicemail playbook first. - Delete old messages. A full mailbox silently rejects new ones on every US carrier. - Check the stored voicemail number with *#5005*86# on AT&T or T-Mobile. If it is blank or wrong, that alone breaks delivery. - Toggle Airplane Mode for 15 seconds, then restart the iPhone to force a fresh voicemail session. - If messages still do not arrive, ask the carrier to reset or reprovision the mailbox. This is a common and quick fix that only they can perform. ## Which carriers does this apply to? | Published for | any iPhone, Verizon, AT&T, T-Mobile and UScellular | | Type | iOS setting | | Good to know | Voicemail provisioning is entirely carrier controlled.
