For most of the 2024 F1 season I was able to watch the practice sessions and the race live on True Visions ch 607 (Bein Sports). However, this season True Visions don't seem to be showing it and ch 607 is currently blank.
Thankfully, Bein Sports are offering the 129 baht deal again in 2025 as my plan B, although the annual subscription seems like good value.
