pc phone tethering

[eastyy]

my current usb wireless dongle broke ...so for the moment i have my phone set up to act as a tether (using the wireless option to connect to my router) someone said to me some phone companies charge it ...but is that only if you are using the data via 3g? is there any charge for just using as a wifi spot

If it's transferring data on wifi it should be free.
