Can anyone explain why I can't access a new voicemail via the appropriate phone key?
I always have to dial 443, which is chargeable.
Plus, is it common practice to have to pay to access voicemails anyway?
Certain phones/os make assumptions about the voicemail number by identifying the network (wrongly) and therefore setting up the voicemail key wrong. Certain versions of android (2.1?) do this for gg.
Just to clarify this point to you - if you have a goodybag, a call to voicemail will only be charged for 1 minute regardless of the number of minutes actually spent listening to voicemail.
