I watch netflix around 1h a day
and write very little enough because 5GB of data volume at home I have Wi-Fi but trz
With 1h Netflix a day, that should be enough for a week.
Download your series and films in the Wi-Fi.
5GB is not as much as you think. The thick, short videos are enough for surfing. However, if you watch Netflix for an hour, you can get a lot of data.
1 hour of high quality Netflix consumes approximately 3 GB of data.
