Android GSM free telephone WITHOUT SIM card (is it possible on WiFi?
A friend asked me because I have free phone lines (e.g., Sideline, Google Voice/Hangouts, etc.) but *all* my equipment already has a SIM card.
Is there a way to get free telephone on GSM Android (tablets or phones) WITHOUT putting a SIM card into the phone?
Does it work on WiFi without a SIM card?
