Carl,
As Carol wrote most smart phones can be set up as a Hotspot. I don't use our smartphones that way because we have a dedicated Hotspot.
Our Hotspot has an unlimited data plan and is no longer available from Verizon. The plans now available charge by the gigabyte, at least from Verizon.
It was easy to set up.
