Question: do any phones support 5g?
Answer: The Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra are all available with 5G connectivity. However, the Galaxy S20 Ultra is the only device in the trio with 5G out of the box. If you're after either the Galaxy S20 or Galaxy S20+, you'll want to make sure you get the 5G model, rather than the standard 4G option.
