I use WIFI on my phone whenever I can. However, there are times I have no connection and I do turn the data on. For about a week now the data will NOT come on. I turn the Mobile Date to "ON" but the H+ symbol that tells me I am connected does not appear. When I try to go on a website (like Facebook) it tells me I have no internet connection. Is it possible that I might have accidentally deactivated something elsewhere? What settings can I check to see if everything is turned on and accurate for my data to turn on.
