Payment per data amount
Sometimes I use Golden Frog a lot, otherwise not. And I pay the same every month. I would appreciate the option to pay per amount of data downloaded.
希望有流量套餐，我不是一直用，但是用的时候可能大量，包月套餐很不划算Hope to have a data plan, I am not used, but the traffic is very big, and use it every time you monthly pa
I think it will be great idea that user can choose how much data plan that they want to purchased with no expiration date.
Example. I prefer to purchased 5GB data plan because i use it to read an article with a few graphic.
Sometimes I download a lot in a month, sometimes nothing in a month.
