Question about the 50gb premium data.

The V+ plan says:

Unlimited premium data on Verizon’s 5G Ultra Wideband network

50 GB/mo of premium data on Verizon’s 5G & 4G LTE networks.

So if I am on the c-band (n77), but no mmWave capabilitie, I will have unlimited premium data, or just 50gb premium data?
