How to not use too much data on my ZTE Valet?

My daughter said I am using data just having all the apps in the Play Store and since I know nothing about this and this is my first Smart phone what do I do to not use so much data?

Thanks for any help you can give me! 

Hi Dolly. You can contact your carrier and maybe request that they put a limit on your data usage. Once limit has been reached, you can no longer use data. See if they have that kind of option or anything similar to that.

Not the answer you were looking for?

Are you on the best cell phone plan?
