I have an iPhone 4S and I use a lot of data?

Is there apps that make me use more please tell me how I can use less!

Only use them on Wi-Fi

Use Wi-Fi when ever you can and don't use apps that would use a lot of data. But apps like pandora and Facebook don't use much but how much data you got and provider I got verizon iPhone 4S and 4 GB of data a month and barley use a 1GB and I use pandora all the time (not on Wi-Fi) and other apps like my jogging app uses GPS to track me and use pandora at the same time still don't use all my data a month.

All you can do is use Wi-Fi or join another company that allows unlimited data like solavei.www.solavei.com/rs87222
