Rollover data

Can someone help me out, I am not sure as to how rollover data works....
If I use 0.5 out of the 2GB I have for the month, and 1.5 gets rolled over, how much will be rolled over to the next month if I only use 1GB of the now 3.5GB I have?
What happens if I don’t go back down below the 2GB mark?

Here, you can see that unused data is rolled over for 2 more monthly cycles. You use the oldest data first, so unless you have way too much data in your plan, you are unlikely to have any expire, but you can easily build up a lot of extra data.8

Each monthly data allowance is good for ~90 days.
 Month 1: 2GB, expiry ~90 days, used 0.5GB
 3.5GB at the beginning of Month 2: Rollover 1.5GB, expiry ~60 days, new data 2GB expiry ~90 days, used 1GB
 4.5GB at the beginning of Month 3: Rollover 0.5GB, expiry ~30 days, rollover 2GB expiry ~60 days, new data 2GB ~90 days
Essentially, your data is good for 3 cycles or until it is used up.

It's basically like each month the unused data you have left will be saved for 90 days. So the first month since you only used 0.5 the remaining 1.5 will be "rolled over" meaning saved for 90days. Then the second month you used 1gb so the remaining 1gb gets saved for 90days while the 1.5 of the first month will now have 60days left. And you're "rolled over" data with the least amount of days "left" will always gets used first. So in the third month if you don't use up all the rolled over data of the previous months (which in your case is 2.5gb) then the 2gb of the third month will just get "rolled over" saved.
If let's say you don't use data at all then the maximum amount of data you can "stack up" with "roll over" would be 6GB considering you only have 2gb/month. That does not include "data gift or upgrades".7
