Troubleshooting Airtel Call Forwarding

USSD says "Service Unavailable"

Use the Airtel Thanks app method instead. Some prepaid plans restrict USSD call forwarding activation via dialler.

Airtel 5G users

On Airtel 5G, USSD forwarding may require switching to 4G first. Go to Settings → Mobile Network → Preferred network type → 4G, set up forwarding, then switch back.

No confirmation received

Try restarting your phone after dialling. Verify status by dialling *#67#.

Contact Airtel care at 121 (free from Airtel) to verify international call forwarding is enabled on your plan before travelling.
