SMARTY Call Forwarding Codes for OnePlus
Dial **21*[phone number]# and press Call. Replace [phone number] with the full UK number to forward to (e.g. **21*07911123456#). SMARTY will confirm when active.
Dial **61*[phone number]*11*30# and press Call. This forwards calls to voicemail or another number after 30 seconds of ringing on SMARTY.
Dial **67*[phone number]*11*30# and press Call. Calls diverted when your OnePlus is engaged go to the forwarding number on SMARTY.
Dial **62*[phone number]*11*30# and press Call. Activates forwarding when your OnePlus is switched off, in Airplane Mode, or out of SMARTY coverage.
Dial *#21# and press Call to check unconditional forwarding status. Dial *#61# to check conditional (unanswered) forwarding status on your SMARTY number.
Dial ##002# and press Call. This cancels all active call forwarding rules on your SMARTY number in a single command. Works from any OnePlus.
If GSM codes fail, ensure you have active SMARTY signal. Alternatively, use the SMARTY app or website to manage call forwarding settings — app-based forwarding does not require signal.
Common Causes of This Issue on SMARTY
| Cause | Likelihood | Fix |
|---|---|---|
| No signal for USSD | High | Try in better signal area |
| Code format wrong | Medium | Use exact format: **21*[number]# |
| Account restriction | Low | Use carrier app instead |
Frequently Asked Questions
What is the SMARTY call forwarding code?
To forward all calls on SMARTY, dial **21*[number]# and press Call. To cancel all forwarding, dial ##002#. To check forwarding status, dial *#21#. These are standard GSM codes that work on any OnePlus on SMARTY.
How do I forward SMARTY calls to voicemail?
Dial **61*SMARTY app → Voicemail*11*30# to forward unanswered calls to SMARTY voicemail. Dial **67*SMARTY app → Voicemail*11*30# for busy calls. Dial **62*SMARTY app → Voicemail*11*30# when your OnePlus is off or out of signal. All three together restore full voicemail functionality.
Why are SMARTY forwarding codes not working?
Forwarding codes require active SMARTY signal to process. If codes fail, try in an area with stronger signal. If the issue persists, contact smarty.co.uk live chat — some SMARTY account types restrict USSD code usage and require forwarding to be configured via the SMARTY app instead.
