We have been long term Sprint subscribers. I was a little surprised yet pleased with the Sprint and Google Voice integration.
The integration is just starting to become available, and if you are a Sprint user with a smartphone, you should seriously consider this.
You go to Google Voice, sign up with a Sprint number, and your phone magically turns into a Google Voice phone. Existing users can go into their list of phones and click a link to turn their Sprint phone into the magic phone.
By choosing to integrate Google Voice on your Sprint phone, you get the best of both worlds.
Voicemail is now naively handled by Google Voice, but the default voicemail app won’t show them. You’ll have to find them in the Google Voice app.
