I'm not sure if it's something I am doing, something I have failed to do, or something Slingshot (my carrier) has/hasn't done, but I cannot get the voicemail speed-dial to work on my Desire. (Manually dialing the voicemail number works though).
I cannot hold the 1 key and conntect to voicemail. Instead it dials a strange number - +6421700700 - which i never put in there - and fails.
If I go into the "settings/call/voicemail settings/" menu on the Desire, and edit the voicemail number - the Desire refuses to take it, giving me a 'voicemail number change unsuccessful. Please contact your carrier if this problem persists." error.
Is this a Desire problem, or a Slingshot problem? Any one know how to fix it ?
