Yes - same coverage.
Actually the 3G plans still use 4G (LTE bands) but they cap the speed at 3mb/s, both up and down. So really many here consider it more of an LTE Lite plan as oppose to 3G. You get the benefit of LTE low latency even if you are on a PM "3G" plan.
It will drop to true 3G and use those band if it cannot connect to LTE, or if you use the settings on your phone to not use 4G LTE.
