A:AnswerIf you are asking whether there is a warranty on the unlocked Galaxy S8, then YES there is a warranty from Samsung (one year). The warranty is no different than if you bought a carrier specific cell phone (i.e one tied to Sprint, Verizon, AT&T, etc.).
A:AnswerUnlocked phones allow a wider access with the possibility of multiple carriers. Even so, it is important to remember that specific devices and setup are required. To serve you better, I have provided a link to the official Note 8 manual and the Xfinity apps that are allowed. http://downloadcenter.samsung.com/content/PM/201812/20181208032100234/EB/COM_N950U_EN_FINAL_180504/toc.html#xfinity_apps_tid1e11187 ^Thomas
