I am going to explain this only once. I have explained this in at least 2 other posts. Maybe even earlier in this post. I don't care to go searching for it. So pay attention.
The reason that your carry over data does get used first is because you aren't entitled to that left over data. For YEARS we never got to keep unused data and nobody every said anything until AT&T started with this thing. You ONLY ever purchased the ability to use whatever your data allotment was. That meant you purchased the ability to use up to say 12GB for $80 so that meant you got a discount and are paying 6.67 per GB. Data is usually charged at $15 per GB. We NEVER purchased the data as a lot to use whenever we wanted.
Now take that 12GB and say you use 8 of it. That means, the next month you'd start the next month with 12 plus 4 for a total of 16GB. If you were allowed to use the carried over data first the following would happen:
You'd start the second month with 16GB and if you used 8 of that then you'd carry over 8GB. This would start the third month with 20GB. Say you only use 8 of that. Then on the fourth month you would have 24GB. If you used only 8 of that then you start the fifth month with 28GB and so forth and so on. You do the math. By allowing customers to bank data like that, pretty soon people would be starting their months with data buckets in the hundreds of GBs all for paying a monthly fee for 12GBs.
Why does anyone need to save that much data?
If you are not using all or close to all of your allotment then you are paying too much for a plan that is too high. Instead of complaining, learn how to better manage your data plan by using wifi and curbing your usage when not on wifi.
