Like Taoman, I also signed up for the lite package last April and I am also going to renew in a few months.
I personally feel it's the best deal going for lite usage customers. I don't think any other provider offers this good of deal for basic simple service. Free incoming calls, and 300 minutes of free outgoing calls, and then $0.010/min after that if you go over 300 minutes. Lots of other features and options to play with as well. Did I mention that E911 is included?
Unlike Taoman, I needed to change my outgoing caller ID after signing up, and with a quick call to support, it was changed to what I wanted. I believe there was supposed to be a charge for doing this after signing up, but I never was charged for the change.
The few times I had to contact support they were very helpful. Not any major issues, but at what they're charging for service, it's a wonder that you get any support at all. Some providers charge extra for support. I believe Anveo charges after so many support tickets.
My only gripe, and I'm really nitpicking, is that this lite plan is strictly to be used with the Obi ATA and no other device. I couldn't even use PP's own Android phone app. It would never register.
Any hoo, as far as call quality goes, I really am a lite user but I haven't run into any problems with call quality.
I'd say to give em a shot, heck for less than $3.00 a month for what they're offering, it's a no brainer.
Good luck!
