I hate voicemail on mobiles, since it seems to kick in after only 4 or 5 rings, but everytime I disable it in the settings menu, it turns itself back on
I hate voicemail too, considering we have to pay to pick up the messages people leave and it doesn't come off our montly call allowance. The only thing to do is to call T-Mobile and ask them to turn off voicemail for you, they might not like the idea as they rake in money for you answering missed calls but they can't deny you the right to have it removed.
I'm not paying for my voicemail in T-mobile. But thats just because i had temp number for 3 days with T-mobile before O2 send me my PAC number and now my voicemail is at that temp number whith im paying for but when im calling old number from O2 that im using its free for me :O
