Call Forwarding Codes for Vodacom, MTN, Cell C & Telkom

Conditional call forwarding isn't a per-network feature — it's part of the GSM standard every South African carrier runs on. That means the same dial codes work whether you're on Vodacom, MTN, Cell C, or Telkom. No app, no settings menu required, just dial the code from your phone's keypad like you're making a call.

Replace [number] below with the full number you want calls forwarded to, including the country code (e.g. +27821234567), then press call.

Divert calls you don't answer

This is "Call Forwarding on No Reply" — it only forwards a call after your phone rings for a while unanswered. Everything else about your line stays normal.

Divert calls when your line is busy

Divert calls when your phone is unreachable

Covers the phone being off or out of signal — relevant if you're somewhere with patchy coverage and don't want calls to just fail.

Turn off every forward at once

If you've lost track of what's active, this cancels all conditional forwarding in one go:

Why this matters for call screening

This is exactly the mechanism ZAVoiceAI runs on. Instead of forwarding unanswered calls to voicemail, you forward them to your ZAVoiceAI number using the "no reply" code above — set once, and the app tells you the precise number to use for your line. From then on, a call you don't pick up gets answered by your AI receptionist instead of going to voicemail, screened, and only rung through to you if it's worth taking.

Nothing about your number changes for the people calling you, and you can turn it off with ##61# at any time.

These are standard 3GPP/GSM supplementary service codes used across GSM networks, including all four major South African operators. If a code doesn't respond on your line, confirm call forwarding is enabled on your specific plan with your network's support channel.
