I’m going to die….

my father feels very enticed by the prospect of paying only $8 per month for internet and wants to terminate the home broadband to use the $8 plan..!!
This is my experience:
Local Data 297.63 GB of 588 GB
Malaysia Roaming Data 33.55 GB of 58 GB
APAC Roaming Data 12 GB of 12 GB
Intl Roaming Data 6 GB of 6 GB
Current Cycle Expiry: 08/11/2024
Started on 9th Oct. time now is 4am 27 Oct.
Router is Deco x50 5G
1. Streaming YouTube videos using Smartube on Android TV box at 720p 30fps 1-2 Mbps (at least 9 hours daily) or mixed with movie apps which consumes around 1 GB per hour and football on weekends (unable to select video resolution, mostly HD)
2. Another smarttube stream on another TV at 720p 30fps 1-2Mbps (at least 3 hours daily)
3. 2 laptops did large windows 11 updates
4. 12 things linked to Google (TV, lights, aircon etc) uses minimal data
2 nights in JB, so no local data used
In short, 17days 290GB.
720p might not be good enough on larger TVs without upscaling.
Have to sacrifice 4K resolution movies
Some movie apps pre-buffers, so if I rewind, it pre-buffers again and consume extra data.
