Unlimited Data services connection issues-

I found a possible solution to this same connection issue problem, I to have been having. On your phone settings go-to Data Usage, under Data graph bar, click on Your phone apps, such as YouTube, click on the box Data restriction, check box. Google play services uncheck data restrictions.

Android OS make sure box for data restrictions are unchecked.

Facebook check data restrictions, Twitter check restrictions. If it has to do with your phone services; Google or Android etc. Uncheck data restrictions. If it's social media or games check data restrictions. If your not sure go-to a Verizon work shop or store for further Help. This may not apply to all phones I have Android Droid Maxx
