Yes you can. You might be behind NAT what this means is your public IP address is being shared with 100s of other users so for the outside world there's no way to reach you.

If you are on IPV6 you most probably will have public unique IP and should be able to access a website hosted on phone without any issue. ISP might not be explicitly blocking incoming packets. NAT was a necessary evil that we needed when we had limited address space. We should move to Ipv6 as early as possible and kill NAT. I think that will open up tonne of opportunities.
