When I got this job I have so many things I just learned about phones. And one of these is if your Wifi is on, you should turn the Data Network off. If your Data Network is on then turn your Data Network Off. This is because if you turn on these two, it would just clash and will make your Internet connection slow.
When your WiFi is on, turn your Data Network off so that your mobile network will not consume the Data usage. So when you feel like you’re not getting enough Internet connection check one of these tools. Make sure that only of it is turn on.
