The last couple of days I have noticed that my phone has been very slow when I open Instagram or even reading articles on the interet. When I'm at home I can connect to the wifi there but once I leave I don't get anything. I have a data plan so I know that's not the problem. I just got the phone about 5 months ago.I have rebooted it several times, no change. I have checked the "Settings - General - Cellular - Cellular Data", and it is turned on. I have also tried "Settings - General - Reset - Reset Network Settings" and there has been no change. Does anyone know what is causing this to happen and a solution to fix it? Thanks, I appreciate any help.
