Question: I have not used bluetooth before, only wifi.  Do you have to have bluetooth service in the area for the keyboard to work?
Document: We are new to tablets, apps & etc. & etc. so this has been a real trial period. We could not get the keyboard to work at first. Finally got a call through to Customer Service and within a few minutes he walked us through the procedure.It would have been much easier with a few pages of legible print instructions that I suspect would cost the vendor 5 cents.
Great keyboard and case work great definitely worth the buy very durableAnd great customer service thank you for the
My Spouse ordered the Case with Bluetooth Keyboard for her Samsung Tab 3 present to me. This is a great combination. With her help I was able to marry the products without error or sparks and smoke!! I got adjusted in just a short time. This is my first Tab and I am VERY HAPPY. My Notebook is no longer my anchor to my bedroom / office. Thanks for a great product and Great Service.
I combined this with a bluetooth mouse and I am able to use my tablet just like a laptop.I docked one star off my review due to the poor customer service I received from the vendor. The first keyboard I received was defective and would not pair with my tablet. It took me two weeks of them not responding to my emails and when they did respond saying that they were waiting on the factory before they would send me out a replacement.
excellent service arrived on time in a perfect package works great connects to  the samsung galaxy note 8 perfectly by bluetooth. the keyboard detaches from four very strong magnets very easily leaving just the case you can use it either way works great very very happy with it.
Setup was very easy as all you need to do is turn on the BT switch and the blue light will turn on (assuming it is charged). Next go to the dropdown configuration menu on the SGN (where you can turn on Wifi, BT, Screen Rotation, etc) and select Bluetooth. The SGN will  scan for all BT units in the proximity and it should be able to detect your keyboard.
Not a bad case, durable and decent leather style material. Keyboard isn't to bad, personally it doesn't work for me because I type so fast and it takes some getting used to due to size.
This keyboard is okay if you're going to keep it on a desk or table, but if you're carrying it to/from school/work like I am, then spend the extra cash for a good one. I used this for one day before the keys started falling off. The case itself isn't snug around the tablet at all. Not a good investment.
For example, in the last case for the word usually I typed the s and it appeared as an s, then the band of fo&#341;eign letters showed up. As the keyboard didn't work I watched the Greek letter Beta take the place of the s. I have no idea why this happens. It has worked this way since the first day I used it.
This is the best keyboard I have ever used before. It reads all of the letters that I type in fact Iam using the keyboard right now. When it shipped in I thought there would be no way that it would  would work because it was so light weight, but after about an hour and a half of charging I got it all set up for my tab 3  and it works perfectly fine for me. Now to the case. It is awesome.
Answer: Bluetooth is a wireless communication system built in to the tablet and the keyboard.  On the tablet you just have to turn it on in the Settings page and pair the tablet and the keyboard.  The first time, if I remember correctly, you probably have to push the Bluetooth button on the keyboard to pair them up, after that they will automatically pair when the keyboard is turned on.
