I have a Verizon Tab, not sure of the name (or how to check that) but here's my problem. My tablet works fine when on WiFi, but when using data. I cannot stream videos, download apps , or use most Google services. But I can still browse the web, Skype, video chat and download pictures, videos, and music. So why can't a stream videos like on YouTube, or download apps, why won't my emails update. I know I have the data, since it works for other things. So why isn't it working for everything ??
