The Hidden Problem Costing Tradies Jobs If you’re using call forwarding or an AI receptionist service like TradieDesk, Telstra MessageBank can be your worst enemy. When MessageBank picks up calls before your forwarding kicks in, you lose potential customers to voicemail - and 75% never call back.

Why ##21# Sometimes Fails to Disable MessageBank

The standard code ##21# is supposed to disable all call forwarding, including MessageBank. However, many Telstra users report that MessageBank remains active even after dialing this code. This happens because:

  • MessageBank settings are stored separately in Telstra’s system
  • Network updates can reset your preferences
  • Some plans have MessageBank as a “sticky” feature
  • Regional network differences affect code functionality

The Solution: Use the My Telstra app for guaranteed results.

Before You Start: Download the My Telstra App

If you don’t already have the My Telstra app installed:

  1. iPhone users: Download from the Apple App Store
  2. Android users: Download from Google Play Store
  3. Log in with your Telstra account credentials

Step-by-Step Guide: Disable MessageBank via My Telstra App

Step 1: Select Your Phone Service

Open the My Telstra app and navigate to your mobile service. You’ll see your phone number and plan details.
