The bad reviews...

...are unjustified in my opinion. I needed a second number for my small business and got one for no charge. It came with unlimited domestic calls and messaging plus voicemail transcription. The app is fully functional and works better with the service than Hangouts, which is little more than yet-another social media grab fest. I have not had one problem to this point.
