Subscriber services on ipad

in the reset menu in settings, it shows "subscriber services" and has the options to either reprovision account or reset authentication key. but i dont have a cellular ipad, its wifi only. so exactly what account does it want to reprovision? also i keep noticing new features showing up on a daily basis in the "experimental features" menu in the advanced section of the safari settings (as seen in the pics). im not sure if these come standard and are included in apple updates but i know that i didnt install them, nor do i own or have ever owned a mac, but under my devices in my google account it shows my ipad as being a mac without an ip address. is this reason for concern?
