I looked thru the FAQ section and didn't see this, and I'm terrible at searching forums, so I apologize if this has been covered.

I am about out of data and still have about 10 days left in my month. Normally this wouldn't be a problem, I would just turn off 3G and only use it when absolute necessary. However on Monday I will be out of town for 3 days and will have limited wifi access so I will need to use my 3G quite a bit. My question is, if I add data now, will I have to use it all before the end of my current month, or will I start a new month cycle and have a month to use the added data?

And as long as I'm here, I just downloaded Tapatalk, but am having trouble finding this forum in the list. Is it named differently there?

If you buy more data, it will reset your date and you'll have 30 more days from the time of purchase.

Cool, that's what I thought it would probably do.

I just had a thought. Since I'm "adding" data, I would think it would keep the data I have now and add some to it. So if I have 23mb left and add 250mb I would now have 273mb. If I did this on the last day of each month I would effectively keep all of my "rollover data" and get to use it all.

No. The new plan begins immediately. There is no rollover data.

So absolutely no point to the popups and emails that say you only have X% left, until it reaches 0.

Except to warn you that your are about to run out of data for the month. Some people might want to know that before it cuts you off without notice.

Yeah, I guess if you knew that you were going to be in the middle of something critical when it ran out you could renew early.
