Call forwarding isn't working

Last updated: April 3, 2026

Use this when call forwarding isn't saving, isn't taking effect, or stops working unexpectedly.

Step 1 — Use an MMI code instead of the settings menu

Device settings for call forwarding can behave inconsistently across OS versions. Try setting forwarding directly from your dial pad:

  • Forward all calls: **21*[number]#
  • Forward when unanswered: **61*[number]#
  • Cancel all forwarding: ##004#

Step 2 — Restart your device after making a change

Step 3 — Check you're not roaming

Call forwarding behaviour can change when you're abroad. Some roaming configurations restrict forwarding to numbers in a different country. If forwarding stopped when you travelled, raise it through the app.

MMI code returns an error or no response

Call forwarding may not be provisioned on your plan. Raise it through the app.
