well, if they can do 1GB then their website is wrong. It could be for business customers.
125$ a month is a lot though (to me). 80MB (for me) is overkill. So doing the math 8% of 1G is overkill and overkill only is 40$ a month. I have no computer skills. I do have google skills

35MB download is needed for 4K Netflix. 83MB is more than double.
Now, if you need 1GB, GB you. Are you going to do it, I would love to know how much better it feels. Maybe I'll change my mind.
