ONE OF THE WORST VOIP PHONE SERVICES OUT THERE, AVOID!
At first (like 10 years ago) they were good, responsive, and fair. But their service has steadily declined over the years, and it has gotten to a place that is abysmal, to put it mildly.
Customer service is non-existent and when they do pick up the phone it's all attitude and no willingness to help at all. It's like they are doing you a favor.
Got charged $4/minute for some international calls!
STAY AWAY. TRUST ME.
