Their "fallback" is CDMA (which is more widely used in the US than elsewhere). The LTE bands for Verizon are pretty healthy in the coverage areas of larger cities - but even now I hit 3G in some areas around my little town.I had no idea Sprint and Verizon were still CDMA.
I have a background in mobile telecoms (Orange, T-Mobile, Nokia, Lucent, Nortel, etc.) so was aware they were back in the day, but figured they would have switched by now.
LTE is pretty much everywhere now (at least in partial locations in most cities) and usually the 3G fallback is good. If you are out in the rural areas then you will not likely have a signal, no matter if you are GSM or CDMA as the profit is not there for them to erect the towers.
Eventually CDMA will be a thing of the past and it will be all LTE - but there's the niggling issue of the cost to roll the towers out for great coverage over such a large area as the US is.
