So for plans with the double data and minutes promotion, does this include double data when going over the monthly limit? (e.g. 300mb/month with the double data promotion, so 600mb/month. If I go over 600mb/month, my account shows "Nationwide Tier 2 Data - ##/200mb $5"). I noticed the standard rate for my plan is $5 per 100mb extra, but since I have the double data promotion from a while back does the double data include when you go over? Will the cost jump once I hit 100Mb? Or is it safe to use all 200mb since I'm paying the $5 anyways?
