I've been on the same plan since 2011. The old $15/month basic plan + Data Saver. Here's a sample from my history of what I've been charged for data according to my bill history: 262MB : $10 + $5 base = $15 240MB : $15 + $5 base = $20 249MB : $10 + $5 base = $15 Any explanation? Either way, those older rates seem to be better than the new ones???
