So I just got a Samsung galaxy s3 last week, this is my third galaxy s phone from the series I love it.. About a few days ago I started having issues with the mobile data, after I reached 2gb of my data I wasn't able to view pictures on Facebook or Instagram or watch videos on YouTube. My data had completely slowed down. I have 6gb of data and on 4gLte. I thought the phone was messed up I did troubleshooting with a Verizon representative and couldn't fix it. I got a phone exchange and still having the same issue... Can anyone help??
