Do the data remain next month？

[timchow]

I am new user this month. I purchased the plan which is 15gb per month. If I didn’t use them all, would I remain to next month? For instance, if I still have 3gb less, would I have 18gb next month.

Only purchased add-on for minutes and data (but NOT for USA) are carried over from one month to the next.

Plan's data(minutes for $15 plan) are use it or lose it. And after you use your monthly allowance of data Internet will just Stop until next renewal.

Unfortunately, remaining data on your account does not carry over to the next cycle.

If you go over within the current cycle, you will need to purchase additional Add-On. 
Here are the fees for Add-Ons:

@timchow   No, regular data on each cycle will reset whether you used them or not and WON'T carry over to the next cycle

Only addon you purchased or bonus addons like those you got from Christmas will remain until all used up without expiry date
