If you use call diverting often but don't want to go through the Pocket PC Phone Edition or Smartphone 2002 menu, you can also use the USSD short codes. This feature is available since the first GSM networks were launched and the phone menu doesn't do anything different than sending these codes. However, this gives you a faster access to your settings and in addition it offers you one feature which isn't available through most mobile phone menus (defining after which time a call should be forwarded if you don't reply). Please remember that this information is stored on the GSM network, not on your GSM device. So doesn't matter if you change your SIM card to another terminal, the settings are stored as long as you don't change it.

USSD codes works in the same way on all networks and GSM phone. USSD codes always looks like:


  • Activate: *USSD_Code# @

  • Deactivate: #USSD_Code # @

  • Delete: ##USSD_Code # @

  • Check Status: *#USSD_Code# @


USSD_Code = the feature code the mobile phone should send to the network

@ = Send (green) phone button

Configuring Call Diverts


Divert all Calls (21)

All your incoming calls will be forwarded, doesn't matter if your phone is switched on or not. The USSD
code is "21".


  • Forwarding: **21*DESTINATION_NUMBER# @

  • Activate: *21# @

  • Deactivate: #21# @

  • Delete: ##21# @

  • Check Status: *#21# @



Divert if no Reply (61)

All the incoming calls will be forwarded if not taken within a defined time. The USSD code is "61".


  • Forwarding: **61*DESTINATION_NUMBER# @

  • Activate: *61# @

  • Deactivate: #61# @

  • Delete: ##61# @

  • Check Status: *#61# @



In addition you can tell the network after which time the call should be diverted. Here the GSM specifications
define a time between 5 to 30 seconds:


  • Forwarding: **61*DESTINATION_NUMBER*DELAY# @



The DELAY time can be 5, 10, 15, 20, 25 or 30 seconds.


Divert if Unavailable (62)

All the incoming calls will be forwarded if the phone is switched off or out of network coverage. The USSD
code is "62".


  • Forwarding: **62*DESTINATION_NUMBER# @

  • Activate: *62# @

  • Deactivate: #62# @

  • Delete: ##62# @

  • Check Status: *#62# @



Divert if Busy (67)

All the incoming calls will be forwarded if another call is in progress. The USSD code is "67".


  • Forwarding: **67*DESTINATION_NUMBER# @

  • Activate: *67# @

  • Deactivate: #67# @

  • Delete: ##67# @

  • Check Status: *#67# @



All Conditional Diverts (004)

You can also activate, switch on/off, check or delete all conditional forwards (61, 62 and 67) with just
one USSD code. The USSD code is "004".


  • Forwarding: **004*DESTINATION_NUMBER# @

  • Activate: *004# @

  • Deactivate: #004# @

  • Delete: ##004# @

  • Check Status: *#004# @



Deactivate all Diverts (002)


This USSD code deactivates all call forwardings with one single command. The USSD code is "002"


  • ##002# @



Please note that using the unconditional "Divert all Calls (21)" overwrites all conditional call forwarding!

Codes will work but have you tried to put the codes into speed dial or using them from a contact entry.  Doesn't work!! You have to enter this long string each time you want to divert...what a kludge. The phone is not a phone!!  :-(

Useful info!

I'm sure these specs are correct but the 004 combined code doesn't seem to work on my T68 (on UK's Vodafone network). I get Unknown Command. Wouldn't be the first time a company's not stuck to standards!

On AT&T's network here in Phoenix, AZ I get that the call is restricted when I try on my t68.

The forwarding menus do the same. So if you odn't like entering these codes you can use the menus.

Thanks for putting these codes online.

I tried the 61 code to increase the delay before forwarding unanswered calls to voicemail.  On T-Mobile Pay-as-you-Go I had to add an extra * before the delay time.

These are not called USSD codes, they're called Supplementary Service codes.  USSD is Unstructured Supplementary Service Data, which is a very specific service.  Above, the article uses various Supp. Services like Call Diversion.  Other services such as Call Barring, Call Forwarding, Multiparty, etc. have similar codes.

@Cellular Guy: Doesn't matter how you call it - it's based on GSM's USSD!
