Sprint Google Voice integration ends June 1, 2018 (productforums.google.com)

This is an end of an era. So much of my call/text workflow revolved around seamlessly using my real phone vs Google Voice VOIP and SMS in apps/extensions across many devices, not to mention the device-independent history of all texts, calls and voicemails. It's also the biggest reason I've stuck with Sprint for over a decade.

This service was a big help to anyone who spent long portions of the day in reception-less areas.
