A:AnswerYes, my co-worker bought the 256gb 6gb RAM unlocked LTE version from S. Korea and it works with his Verizon SIM. It is unlocked and has ALL LTE bands. Also works with T-Mobile as I used my SIM in it too to check it out.
A:AnswerNo, as long as you purchase it unlocked (aka buy it with 1 payment). I used my Tmobile SIM card and it recognized it right away and works 100% perfectly.
A:AnswerIt is not possible to use your old SIM on this tablet because it is contracted with Verizon for the customers who purchase the tablet with new line or new account. If you want to use your old Verizon SIM, you need to purchase the tablet for outright price of $749.99 and contact Verizon so that they will make it unlock and use can use any carrier in it.
