What I really love is that they do true cash-back for unused data, not rollovers, etc.
When I went home to India it worked very well, likely because it just hopped on to a good network. Coupled with really cheap roaming data, and automatically using google voice for all calls, its simply awesome.
- Customer service is exactly what it should be, accessible, excellent, quick, friendly and timely. It feels a bit like stepping back in time 40 years.
- The service works very well considering it's combining the coverage of 4 different networks (3 mobile + wifi)
- call quality on the mobile providers is about what you'd expect from them, not as good as AT&T or Verizon
- call quality on wifi is great
- the additional built in services and integration into the phone are really well done: simple website to service the account, reasonable pricing, automatic voice transcription of messages
I'm pretty impressed with how consumer friendly it is.
(The brand protectionism is really starting to hurt their ability to be scrappy.)
