Which is the best: 1GB valid for 1 day, 1GB valid for 30 days, or 10GB valid for 30 days?

I don't care if it's expensive as long as I get the best plan in terms of data usage. I don't know anything about computer science, so which one we be the best I get from my Internet service provider?

10GB for 30 days will give you the most for your money, provided the pricing is the same.
but it's just basic math, nothing like Computer Science...

total usable data 1gb per day is best (30 gb total) BUT if you dont use the data per day it goes away
1GB per 30 days is a joke (super low data)
10GB for 30 days is the next best
