I had a galaxy s3 for about two years and I had the unlimited data plan. I used about 13 gb about month because I stream a lot of Netflix and YouTube videos, and use social media websites and the Internet never slowed down. I recently purchased a galaxy note 3 about 4 weeks ago. My Internet plan wasn't change at all, but now my Internet slows down after 5gb or less. I callled Tmobile and asked them what was going on and they told me I've reached my limit, but I explained that my Internet has never slowed down even after using more than 10gb, and that I've always had the unlimited data plan. I don't understand what's going on. How is it that I never had this issue and now with a new phone, I can't use my Internet as much as before? How did my Internet never slow down after 13gb, but with 5gb on my note 3 , it does?
