Trueroots vs RelianceIndiaCall vs AirtelCallHome

[mypath2usa]

Hi All,

I'm starting this thread to compare these three calling card companies & add more if you wish. I'm specially interested in knowing about trueroots. I used to use Reliance and then moved to Airtel (when they started nice deal in starting) but their services sucked badly. I then moved to Pingo. Now, I see Trueroots' ad all the time in international channel and it's backed by TATA also.

Please share your experiences !
