Replacement of a device is done with the same device or one with comparable features The EVO 3d is a 4g Wimax device the HTC EVO LTE has different features and is a more expensive device. It is very unlikely that Asurion would replace with the newer phone with different capabilities
Is Total Equipment Protection called Asurion or is it a different insurance thing?
Asurion is the insurance company that does the processing for Sprint's Total Equipment Protection, they honor the Lost/Stolen/Liquid damaged/Physically damaged devices. If it is something that is mechanical or electrical failure, like a blown speaker, screen black, mic out, etc. then that may be fixable or exchanged in a Service and Repair store without a deductible through TEP.
Sprint's protection plans are not upgrade programs. Phones are repaired if possible, exchanged for the same model if it can't be fixed in store, and only if an exact model replacement is not available is a roughly comparable model offered instead.
Oh and I would like to add:
Almost 99.99% of the times, it's a refurbished phone, and with what I've read around here is correct, most of the times those refurbished phones are just not refurbished at all but just an used phone that was returned because of a problem and they send it right out to you again
Sorry about the necropost. But, I'm really digging the faulty EVO3d you guys sent. Do they even check these things? The one that was sent has a blown earpiece and a touchscreen that bugs out like somebody is touching it on the upper edge. The one I just sent back for a touchscreen that bugs out on the lower edge. Also gotta love that cheap glue/double sided tape that lets go around the trim... That's one bunk replacement so far. Considering that the replacement has the same issue as the one that's replaced plus one I have serious doubts I'll get a working one in return. The tech at the store was able to verify the bunk replacement and another EVO3d is on the way.... Urgh. To think that I would've been better off keeping the original one and not bothering trying to get it replaced and tried fixing it myself because as my luck would have it the replacements will be worse. Merry Christmas.
