While China and South Korea are already firing up 5G work in Asia, Thailand is still behind in 4G service deployment.
Local sources reported that Thai mobile operator True Move provides 4G commercial service in the country on a limited scale.
It was even mentioned that mobile operators in Cambodia were already providing 4G commercial service in 2012, the year when mobile operators in Thailand were only beginning to roll out 3G networks.
