Inside settings, if I select "Call settings", then either "Call forwarding" or "Additional settings", I am unable to change anything. As long as I stay on the "Call forwarding" or "Additional settings" screen, I just get the message "Reading settings..." and a perpetual spinning progress wheel.
My phone is the myTouch Q (with slide-out keyboard). I just got it a few weeks ago, and have it mostly set up how I want... but still need call waiting and caller id working. I'm fairly sure my plan supports these options ("Even More" plan).
If you are connected to wi-fi or wi-fi calling while you try to access these options, they may not work. You have the option to either disable wi-fi calling and then try to view these settings or see the chart below for short codes that will help you change these settings.
Enable CFNRc from dial pad (*62*DN#)
Disable CFNRc from dial pad (##62#)
Enable CFNRy from dial pad (*61*DN#)
Disable CFNRy from dial pad (##61#)
Enable CFB from dial pad (*67*DN#)
Disable CFB from dial pad (##67#)
Disable Call Waiting from dial pad (#43#)
Re-enable Call Waiting from dial pad (*43#)
Please let us know if this helps!
Thanks very much for your help! I have been able to activate call waiting using the code (*43#).
I'm still confused about setting up call forwarding, however: I've tried a few combinations, including *61*DN# (although the 'D' key seems to be disabled when the dialpad is active), *61* followed by the number I'm trying to forward calls to, *61* by itself, and a few other combinations...
The result in most cases is a window with the message "Call forwarding Connection problem or invalid MMI code".
In other cases, it makes a call, and I get a voice message: "We're sorry, all circuits are busy now... message CA84055"
I did also try both turning off wifi calling, and disabling wifi altogether, but in both cases I still have the same problem (eternal spinning progress wheel) when trying to change call waiting/call forwarding settings with the GUI.
Aha, one more follow-up: I found more explicit instructions on call forwarding here: http://wiki.howardforums.com/index.php/T-Mobile_Conditional_Call_Forwarding
To activate forwarding on no answer, **61*+<country_code><phone_number># [SEND[ (forward on no answer)
Cheers, and thanks again for your help!
Try these codes with wi-fi off:
