What happens when you don't use all the 250MB in 30 days? Does it keep going beyond 30 days until you use it all up? Or will AT&T ask you to update your data plan to another 250MB or unlimited? If you opt for another 250MB, would your unused MB be added?
I ask this because I use Wi-Fi most of the time and have my 3G off until needed.
