Help making calls while tethered

[4tunesmiles]

Hi. Should I be able to make or answer phone calls on my non-rooted EVO while USB tethered to my pc without losing my internet connection on the pc?
It seems like I could at first, but now I cannot.
And ironically, we decided to drop our land line last month. Now its like I've been plunged back into the 90's dialup days of can't be on the phone and internet at the same time!
Is there a fix?
Thanks

i believe you can only do both on 4g. but i am not 100% sure because i don't have 4g in my area. but i do know for sure that you cannot on 3g.

you can not use 3g and make phone calls at the same time.

you can make phone calls while using 4g and wifi
