Since night time internet packages are cheaper, sometime costing half of the regular price, I subscribe to night time internet. Currently, I have subscribed to night time data package on my phone. The volume based service cost me $3, which otherwise would cost me $6. By paying $3 I was getting 6.5 GB internet volume, which other wise would be just 3GB on a regular data service. Since I have a day time job, I don't have internet surfing time on the day. Night Internet comes very handy.
