The issue is the import phones I want to buy don't suppprt those bands. An example phone I might want (Xperia 10 IV) supports 12 bands for LTE, my carrier (US T-Mobile) supports 6, but the intersection is only 2 bands (the old GSM bands) and I know my carrier doesn't always have coverage on those bands. I've got enough dead zones without throwing out 4 bands.
