Vodafone Germany: Voicemal notification via SMS works with Vodafone visual mailbox
Vodafone Germany offers a service called "visual mailbox", it's based on MMS.
I know that the iPhone is not MMS capable, but after I switch this service on, the SMS notification works on my iPhone :)
If you live in Germany,
- dial 12051 from your iPhone
- press 1 for switch visual mailbox on
- hang up
during the next 2 hours you will receive a SMS that visual mailbox is now working
All existent voicemails stays on the system and you can call your voicebox as usual.
Hope this helps, but unfortunally only for iPhone user in Germany
my 2 cents
