Call Forwarding on iPhone

  1. 1

    Settings → Phone → Call Forwarding

    Open Settings. Tap Phone. Tap Call Forwarding. Toggle Call Forwarding on. Tap Forward To and enter the phone number to forward calls to. Calls will now forward to that number when your iPhone cannot answer (based on the forwarding type set by your carrier — usually forwards when no answer, busy or unreachable).

  1. 2

    Phone app → Settings → Calls → Call Forwarding

    Open the Phone dialler app. Tap the three-dot menu → Settings. Look for Calls or Supplementary Services → Call Forwarding. Options appear: Always forward (all calls redirect), Forward when busy, Forward when unanswered, Forward when unreachable. Tap each and enter the destination number.

Using Carrier Shortcodes (Works on Any Phone)

Dial these codes in the phone dialler:

  • *21*[number]# — Forward all calls to [number]. Example: *21*0412345678#
  • #21# — Cancel all call forwarding
  • *61*[number]# — Forward when unanswered
  • *67*[number]# — Forward when busy
  • *62*[number]# — Forward when unreachable

These shortcodes work on Telstra, Optus and Vodafone networks in Australia.

Call forwarding costsForwarded calls are typically billed as outgoing calls from your number to the forwarding destination — they use your call allowance or are charged at your standard call rate. Check with your carrier before setting up forwarding if you are on a limited-call plan. Most modern plans with unlimited calls include forwarded calls in the unlimited allowance.

Yes — call forwarding remains active when you travel internationally unless you turn it off. Calls forwarded internationally are charged at international call rates, which can be expensive. Disable call forwarding before travelling overseas unless you specifically want it active (and are prepared for the costs). Voicemail is a better option for missed calls when travelling.
