I understand that if you have activated the wifi signal or you do not have wifi, 3G enabled, but if you want to be active there any way to disable it in the settings, or so goes a line if you hire 3G or 4G, in my case I have not set it for now and use the sim only for wifi, but when I put a sim and not have wifi and not be hired if not voice, will activate the 3G, I say the bill.
Thank you very much.
