Megabyte or Gigabyte?

I got a question. Im thinking of switching my internet provider but there's a limit capp on internet data. The spped I want is, 10GB download speed and 3 Upload speed, and 100GB download & upload i can spend a mouth. So how much data dose Final Fantasy XIV spend a mounth in gigabyte and megabytes?, 7 hours aday for 30 days?

you mean while connected to a server? less than 1 GB i am sure about that. probably around 50 MB a month

like data used connected to server like recive and sens data. im guessin its like 25 GB at 7 hrs aday for 30days

3gb only about 13-14 days for me 24/7 when im using.
