I switched a monthly Tmobile plan several months ago and absolutely hate the voicemail "service". I previously had all my VM's sent to my email via YouMail (kind of like Google Voice).
Today while looking through settings I noticed there are three Voicemail Forwarding numbers in the Phone Settings menu. Each for a different scenario (busy, unavailable, unreachable). All numbers are currently set to Tmobile's VM handling number.
Has anyone with a TMobile monthly plan had success in changing these numbers to use a third party VM service such as Google Voice or other?
