Because when I set in dead placs at home where I don't have carrier signal, internet stop working. Also, when I switch off my Mobile Network, I became not able to use the internet. Also, people told me that the WiFi signal will be colored when it's used so, it's using the data package and it's really too slow in surfing. I want to use the Wifi because my wifi internet speed is broadband 8 MB.
Any help
?
