The only way it would not would be if the ISP only allowed TCP ports 80, 143, 443, 465, 587, 993, and 995. Many public hotspots in my area do this plus deep packet inspection. You would need OpenVPN or SSH for a TCP-based VPN and then a means to disguise your traffic to look like an https session, over say, port 443. It’s not easy to defeat but very doable.
