Generate the correct code to forward calls if unanswered after a set delay
🔔 Important Notice
Some networks may forward to voicemail instead of your number unless voicemail is fully turned off.
To disable voicemail: Dial 1760
and press Call
To turn it back on: Dial 1750
Must start with +44 (UK numbers only)
Use the tool above to generate your GSM forwarding code. Fill in your mobile provider, the phone number you want calls forwarded to, and your preferred delay (we recommend starting with 10 seconds).
Copy the generated code and dial it exactly as shown in your Phone app. Press Call and wait for a confirmation message from your network. This activates forwarding for unanswered calls after your chosen delay.
Call your mobile number from another phone (or ask a friend to call you). Let it ring for longer than your set delay without answering. The call should forward to your chosen number.
If the call successfully forwards to your chosen number, you're all set! If it goes to voicemail instead, proceed to step 5.
If calls still go to voicemail instead of forwarding, you'll need to temporarily disable voicemail:
To turn off voicemail: Dial 1760
and press Call
To turn it back on later: Dial 1750
After disabling voicemail, test the forwarding again (step 3).
If you're not enjoying the call forwarding or want to turn it off, simply dial ##002#
to cancel all forwarding settings instantly. No fuss, no fees.
GSM codes are standardised commands that have been built into mobile networks for decades. We didn't invent them—they're part of the original GSM (Global System for Mobile Communications) standard that's been around since the 1990s.
Think of GSM codes like secret shortcuts built into your phone's operating system. When you dial a specific combination of numbers, stars (*), and hashes (#), your phone sends a direct command to your mobile network's computer systems.
