When I look at Data Delivery options under Data Management under the phone's main settings, there are 2 options - Background data and Data Roaming. I have them both checked. Under Data Roaming, when I check it, it gives a warning that significant roaming charges could occur if acquiring data while roaming. Does that apply to folks that have the $30 data plan, or does the plan cover us whether or not we are roaming? In my local area I'm never roaming, but could be in some areas when traveling. Any clarification would be appreciated.
