I am looking to buy the 4G note 10.1 and use my current verizon 4g phone sim with unlimited data in the tablet. I know I will need a micro sim adapter but what else will I need to do to buy this tablet and make it work without losing my unlimited data? I tried to go through the purchase on vzw.com and add a line but it was going to force me in to a share everything plan. Can i but the tablet somewhere else or get it without service through verizon? Can I use the tablet then to send and receive calls?
