Pros: Great rates, especially to Asia
Quick setup, no fuss, easy to use
Registered phone numbers mean no hassle with calling card numbers, passwords, etc.
Cons: Occasionally spotty service (ie call is slow to go through, or doesn't go through)
Occasional poor quality connections
Summary: I didn't know what to expect from a discount service, so I was more than pleased with TCI. Sure, there was the occasional long wait for a connection, or failure of a call to go through. And sometimes the call quality was so-so.
But the savings are so huge that it's definitely worth it. Also, I had one occasion to call customer service, and my call was answered promptly.
I had two phone numbers "registered" to use the service -- my home phone and my cell -- which meant that if I called TCI from those numbers, I didn't have to provide a PIN. This was very convenient.
I'm now using Skype when I can call from my computer, but otherwise TCI is hard to beat.
