In which country 7G network is available?

The statement that 7G networks are available in countries like the Netherlands, Hungary, and Norway is incorrect. As of 2023, 7G technology does not exist commercially anywhere in the world.

We are currently transitioning to 5G networks globally, with South Korea being a leader in its deployment. While research and development are ongoing for future generations of mobile networks (6G and beyond), we are still several years away from any concrete standards or commercial implementations of these technologies.

The Netherlands, Hungary, and Norway are indeed considered advanced in terms of their internet infrastructure and digitalization. They have high adoption rates of current technologies like 4G and 5G, and are actively involved in research and development of future networks. However, attributing 7G availability to them is factually inaccurate.
