Pull down the notification bar and ensure Mobile data is on. If not, turn it on by touching that option.
In addition, you won't automatically be connected to other WiFi networks unless there is no challenge or TOS agreement screens, etc. You may need to confirm agreement on a webpage to connect to some free WiFi networks.
I wish it were as easy as me being an idiot! Mobile data is on and WIFI is working as well when I have the issue. I downloaded the Hotmail app and it is working. Just wish it would work like it is supposed to. I read another forum where there was a problem with the sim card. I will have to go to the store when I get a chance. Thanks for trying!
