MY new Iphone 6plus is using an excessive amount od data for the voicemail app. I have the cellular data turned on and the phone app set to not use cellular data. It sucked down 3.2GB in less than 24 hours. When I receive a voicemail the phone starts using data at a very high rate and doesn't stop until the phone is reset or the cellular data switch is turned off. Is this a verizon problem or is it an apple problem? Somebody owes me a refund of several GB of data.
