Video: Mobile data not working in android device (Samsung)
in case if the mobile data in your android device is not working then the first thing what you need to check is you need to check the strength of the cellular signal in your android device. It should be strong. If you are out of coverage then you need to go to the area where you have coverage and the next thing what you need to check is you need to check how much of the data is left in your android device. If you have subscribed to the unlimited data then it is ok but if you have subscribe to the fix data plan then you need to check how much data is left in your android device and the last thing what you need to do is you need to go to the "Settings".
You need to go to "Connections". Go to "mobile networks". Then go to "Network mode" and then you can switch between this Network mode to check if the mobile data will work in your android device..
