Hi there! I am using iconia w4 with 3g support. 3g data connection works fine. But, I was wondering if it was possible to make voice calls as well, or at least was able to use some keypad to dial numbers for balance inquiry, package subscription information etc. I tried to use skype keypad but no luck. I tried to make call to this sim from other phone. Ringtone is heard from other side but nothing happens on w4 tab. I think I need to install some software with phone kypad function which can access the huawei 3g module on board to make voice calls. is it possible?
