ZingoTel went out of business in May 2009. Please continue to post reviews, though — knowing the history of VoIP will help other consumers make better choices.
UPDATE
I wrote the following and now must re-cant... I like most of the other folks on here have now fallen prey to Zingo's tactics. I made a my phone has not worked in over two weeks... NO one at customer service (I knew that) I will now switch... IT was good for a year now is garbage... I used to be their biggest fan... Now I caution you to stay away...
Original review: (I apologize for leading anyone to this service)
Can't beat it
Anonymous from says: I've had Zingo tel for over a year. I have an Oakland phone number and an ALabama phone number close to where I move. I have had ABSOLUTELY no problems using this service. I rarely use the phone $14.95 for unlimited ( I may go back to the $9.95 for 400 minutes.) is unbeatable. Sound quality from cordless phones in and around the house is clear as Ma Bell. I had Vonage but could never get it to work and is $10 more and the customer service was lacking. Zingo's customer service is hard to contact for some reason, but if you reach them, they'll take good care of you. Zingo... best kept service.
