Just to clear this all up:
I work in Best Buy Mobile currently and have been for three years. The protection plan used for the Triumph (and any prepaid phone sold through Best Buy) uses a GSBTP-R, also known as a PRP (Product Replacement Plan). If you were to redeem the protection at a Best Buy location the associate would give you a brand new phone. There is absolutely NO repairing of prepaid phones and there has never been. If the phone is no longer carried (lets say, in a year theoretically) you would be offered a phone of comparable value. Lets say the new device they offer you is $250, you would get the brand new device as well as a $50 credit being that the Triumph is $300.
As for what the plan covers, it's pretty vague. Best Buy is the kind of place where what is written on paper is generally not always followed to deliver a customer experience. Physical damage is not technically covered by the protection plan. However, customers get fulfillments on damaged prepaids all the time. Same goes for water damage, its not covered, but I'd be surprised if you didn't get a replacement. The reason for this variation is because Best Buy employees are told about many different policies and it really varies by specific district and territory. For example, one district may see an overflow of prepaid PRP fulfillments and get strict about it, while others might not give a shit if you exchange a soaking wet, deformed device. Like I said, its vague. But what most don't realize is that Best Buy really tries to take care of the customer, so if someone tries to deny you physical damage coverage, just speak to a manager. 9 times out of 10 they'll get you a new one.
Lastly, a few people in this thread are confusing the PRP with the GSBTP or PSP (Product Service Plan). In Best Buy Mobile it's reserved only for contract devices. It's either a monthly or outright price and varies by retail phone cost. Like I said, nothing about this plan has anything to do with the Triumph. Some people have had bad experiences with the PSP in the past which is why you'll hear a lot of people complain about it. Best Buy has used different repair companies and policies throughout the years. As recently as last year it was taking over a month for phones to be repaired. The system that's now used implements a "rapid exchange" which takes about three days. There's also never a deductible and an unlimited amount of "rapid exchanges".
Not every protection plan is worth it at Best Buy. However, on the prepaids you get the best deal. They are super cheap (even for a $300 phone) and have the least amount of hassle involved. Why go with Virgin's insurance? It's $50 for the year and you pay a deductible. Hope I cleared some things up!
