conditional Call forwarding on Nexus/GPE phones
I have htc one m8 GPE (Google play edition) Marshmellow. Before upgrading to M i was able to (conditional) call forward to my google voice number.
But recently I have not been able to (conditional) call forward to my google voice.
I have tried these dialing (considering my 10 digit phone number = 1234567890)
from my phone. I get following error.
Connection problem or invalid MMI code."
I have also tried phone app> setting > calls > Call forwarding > enter my number
I get following error
"Call settings error
Unexpected response from network"
