That should work, but with NAT in your ISPs network. The address is
part of the "Shared Address Space" for carrier grade NAT. See
If it doesn't work for you then there is something else wrong. Your
operator has assigned that address to your link, so we must assume it is
intended to work. But maybe not for Internet? Are there other APNs you
can use? Can you verify that the APN you are using works (for Internet
access) on e.g. a phone?
