A:Answer Actually since I went to Best Buy to get my phone instead of the service provider store, I was able to lower my billing but not lose any of my data plan. I have the lowest data plan (3GB) and it's plenty for me. Everyone is different and requires different amounts of data. I use my WI FI at home and at work to save my data usage too. I don't recommend using free public WI FI. Data plans cost just depends on how much streaming, downloading and playing on the phone that you will be using AND of course your provider. I use mine, for watching videos, playing games, social media, research, GPS, sending photos, plus updates for my malware/antivirus (which you can get free at the Google Store).
