Pros: Great rate, no problem changing, no problem with service so far, no unpleasant surprises on bill.
Cons: None we know of yet.
Summary: I've switched our previous three lines many times over the last 10 years and had problems with every switch and with previous companies eventually charging services undisclosed at offering, and terrible customer service in many cases resolving difficulties. We haven't made any international calls nor many long distance calls yet to really evaluate, nor have we had occassion to use customer service, but so far NO PROBLEMS or FUNKY BILLING. Only reason I can't endorse voice quality as excellent is because we haven't made enough calls to be sure it never drops out.
