I've worked for Sprint Corp retail for 5 years and now at an indirect agent. Here's my take. We have a service department and we see every issue known to phone. With sprint protection plan you get so much more that's not mentioned in the brochure. Start with the Total Equipment Protection app in the market. Its free. It backs up, restores and wipes contacts, Shows you were the phone is if its lost, makes it ring even if on silent and shows you were the phone has been every hour for the past five hours. Its super non-intrusive.
Service and repair options if you have TEP with Sprint - We replace completely shattered screens for free, batteries a lot of the time if a cell bursts or other issues for free, if we have them in stock. Can replace housings etc. Replace speakers and buttons and keys. I could go on and on. I see first hand from behind the counter how hard our guys work to do what ever they have to to get your phone working again. It may mean raping and pillaging another phone for a button or housing. It never hurts to go in and introduce yourself to the tech, ask for the lead tech and get to know him. just say you wanna meet the guy servicing the phone and it always makes it more personable to him and he'll do the repair with a little more urgency and diligence. Don't be the guy who gets all up in his face or he may be more inclined to make you wait while he orders a new one or insists it needs a wipe. Don't bite the hands that can fix your phone or make you spend days re-customizing
Best Buy is OK i guess but Sprints options are much better. If a replacement has to be ordered and is ordered before 2pm you get it next business day. If you must go thru Assurion, if its ordered before 7pm or 8pm cant remember then you get over-nighted the next day for free
