Get rid of your cell phone company, keep your cell phone: Google Voice Calls Through (Your Own) Yate server w/Internet CallingSubmitted by AnAppealToHeavenWash on Mon, 01/28/2013 - 09:08
This works well over WIFI and also over any decent CHEAP no contract data plan without the need to pay for minutes used.
I use a prepaid SIM card that I can activate by the day ($2-$3) or by the month ($30) when I am not near WIFI.
Even if the SIM card is not active the Android phone can still make emergency 911 calls when I'm not within range of WIFI so its perfect even in emergencies, even for those like me who prefer to carry a gun and have not much use for 911.
Google voice manages all my texts and messages for free, transcribes voice mail to text and blocks call spammers. It acts as my personal secretary for FREE.
