tl;dr: 1 minute of HD video = 1 MB. 1 hour of HD video every day = 17.6 GB of data in a month. Approximately.
This is my setup
I have a data sim in my iPad Pro, and i subscribe to a monthly internet package. I have tried various packages over the years. Sometimes it’s 60 GB/month, sometimes it’s 3 GB/month. Sometimes i max it out, sometimes i don’t.
I was curious to see how much data i actually need. The main factors are:
Time is an important factor because having the data doesn’t matter if i don’t have the time to use it. For example, if i work full time and only get 1 hour a day of entertainment, and say i spend that on watching Netflix, an hour watching high quality video would equate to apprx. 600 MB. One hour every day in a 30 day month would mean 18000 MB, which is 17.58 GB. My entire month’s data usage is then less than 18 GB.
As far as bandwidth goes, i do have a PTCL DSL connection (12mbps) as well, which works well most days. And i also have 1.5GB of data on my postpaid mobile plan, which can serve as emergency backup for Slack calls. The internet SIM is not the only connection i have, so it’s not the end of the world if i max out on data.. I can opt for a data plan that
All video content i watch has to be 720p minimum.
