Yes! You should also be able to do it in a 3G area with this phone. Although I have never tried surfing in 3G, I have received emails while on a call. This leads me to believe I had an active data connection while on the call.
I have also talked on the phone (using 3G or LTE) while tethered devices have been surfing on the internet, sending & receiving emails, streaming music and/or video etc. at the same time. Worked well for me.
