After three attempts, I finally received the correct SIM from Sprint today. As mentioned above, the UPC is 019962040146. On each request, they mailed me one at no charge. Two of the three were even sent overnight.
My Pure is now active on Sprint's network. I did extensive testing, and found that does indeed access all three of Sprint's LTE bands (25, 26, 41). I ran speed tests on each, here in central Florida. Band 41 is by far the fastest, at least in this area.
So, once you get past the hurdle of getting the right SIM, the phone will work like any other Sprint phone, on all of their available resources.
