Welcome! What do you mean by pairing your phone to the tablet? Are you trying to use your phone as a wifi tether, so that you can use your tablet to access wifi without finding a public hotspot? If so, then are you paying extra to your wireless provider to allow wifi tethering? If so, then all you need to do is activate your phone as a wifi hotspot (the phone should have come with an app for that), turn on your tablet's wifi, and connect to that hotspot.
If you aren't paying the wireless provider extra, then there are a few 3rd party apps you can download that allow you to tether. The popular is Foxfi--give it a try.
