How many mb / gb internet does an online game cost me?

Let's say I want to play fortnite on my ps

i take the internet but from my cellphone i say i make a hotspot

how much internet does it cost me to play eg per hour

Between 45MB - 100MB

I had this experience with Leauge of Legends. Could end a match (40-50min) with about 1-2gb haha. However, I do not know exactly how it is with Fortnite. However, I guess about the same.

According to the Epic Games forum, around 45-100 MB per hour.

It's best to just gamble for an hour and then check it out yourself.

It always depends on where you are. (I in a village, away from the city → cost more!)
