"Three" Mobile network charging

[NiceCupOfTea]

Can anybody tell me what is covered in their inclusive minutes? I found a bit in their Ts&Cs that implies that all land lines and voicemail are NOT included:

Do a ctrl-F "voicemail" and look at the 3rd search result:

"Inclusive voice units in any price plans or Add-ons are for voice calls made either from the
UK or while in a Feel At Home destination to any other standard UK mobile (beginning 07
but excluding certain numbers – see page 8 for details) landlines (beginning 01, 02 and 03)
and voicemail (retrieved by calling 123 from your mobile in the UK)."

Currently on Orange on a 30 day rolling contract but just rang them to find out why I am paying 3x what they quoted to see various bundles I have been opted into but crudically voicemail seems to be 50p/min or something! This is a big add on with a £13 monthly contract!

Hmmm, I'm looking at the 4GB / 600 mins contracts, either on a 30 day or 12 month contract. It seems really hard to work out what's what.
