I am using golan telecom on moto g5s. Whenever my phone switches from wifi to mobile data, internet gets disconnected although it is still connected to the network. I always have to reboot the phone to use mobile data. Please help.
Are you sure it's not just getting disconnected from the site or web app it was connected to? Switching internet connections make you a different user to web servers. If the data actually turns off (in settings), contact the place you got it from - it's probably a defect in the phone, and it should still be in warranty.
