I can only connect to the internet when I turn on my data. I cannot browse even tho I am connected to my wifi connection ONLY. Will I be charged for data use when I have a wifi connection?
You shouldn't have to turn on data to access Wi-Fi. As Robert mentioned, if we knew what device you are using, we could troubleshoot the problem further. A word of caution, if you forget to turn off data, or get out of range of the Wi-Fi signal, even for a few minutes, your device will automatically revert to data and you will get charged for data usage.
