A:AnswerThe Samsung Tab S2 9.7" does has a 4G LTE option. It runs for 100 dollars more than the regular Wi-Fi one. You just have to make sure that your phone carrier will be compatible.
A:AnswerIt only has 8GB built in (about 5GB available to the user), one of the few downsides of the unit. You can put an SD card in (32GB max) and decide whether to use it as "portable" memory (for things like pictures and video files) or "internal" memory (for things like apps). If you do it as "portable" then other machines (like a windows computer) will recognize a separate SD card memory area for you to put things like pictures and video files. If you do it as "internal" then another device (like a windows computer) won't see the extra memory (only the tablet will recognize the extra memory) so you first have to put your files to the small built-in memory, then move them over to the additional "internal memory" that the SD card creates. A bit of a hassle, but doable. If having a lot of memory for a ton of apps is important to you, this may not be the tablet for you. But if you can get by with what you get (or using the above methods with an SD card) the tablet has a really nice, sharp, bright 1280x800 screen and very good battery life. To each his own.
A:AnswerBasically both
But honestly you can find more options in bestbuy.com .
I love browsing in the bestbuy store and I have checked that sometimes you can see the same open-box product in the store with cheaper price and the same condition
