When using Google Voice for texting, do the numbers you text / call appear on a t-mobile cell phone bill?

I am looking into using Google Voice to for some texting / calls. My only concern, is that these transactions will be viewable on the cell phone bill. Does using Google Voice bypass your cell phone carrier, or does something still appear on the bill?|||texting will not appear on the bill, since GV uses data/internet to send/receive SMS. no numbers you call will appear on your bill either, unless you (or the bill payer) has specifically requested to see each call made on the phone
