It means the catalog draws live channels and on-demand content sourced from over 190 countries, not that every regional channel from every country is included in full. Coverage varies by country — some contribute a handful of channels, others contribute much more — so world is really a floor on breadth, not a promise that any specific country's full lineup is present. Checking a provider's stated country count against your own list of countries you actually want gives you a real answer; the word world on its own does not.

IPTV delivers over standard internet, so a line that works at home generally works anywhere you have a stable connection, including hotel Wi-Fi abroad — it doesn't check your physical location the way some geo-restricted streaming apps do. What changes while traveling isn't the subscription itself, it's your local network quality: 4K needs roughly 15-25 Mbps and 1080p needs about 5-8 Mbps, and hotel or public Wi-Fi often can't sustain that consistently across a whole evening, which shows up as buffering that has nothing to do with the subscription and everything to do with the local connection.

No. A VPN changes what your internet provider can see about your traffic — it doesn't change the underlying content licensing of any service you happen to be streaming through it. That question comes up directly for people searching international-TV options, and the honest answer is that a VPN is a privacy tool, not a legal one: it doesn't turn a service's catalog into something it wasn't already, and it doesn't answer questions about any individual provider's own terms, which depend on that specific provider, not on whether a VPN happens to sit in front of the connection.
