Do you have your mobile data switched on? You can check this easily by dragging the notification bar down from the top of the screen and selecting mobile data. This icon should be green.
If your mobile data is turned on and it still isn’t working, you can do an automatic search for available networks. To do this, go to Settings > More networks > Network operators > Select relevant operator.
If this is not successful, try using a different network SIM card to establish if the issue is with the device or the network. If another SIM doesn’t work, please check out this link to find your nearest walk in service centre: http://www.samsung.com/uk/support/servicelocation/
However, if another SIM card does work fine in the device, I recommend contacting your network provider for more information regarding their mobile network connectivity.
I hope this helps.
