Sprint is currently pushing their "NK4" update; for (limited) details, see https://community.sprint.com/baw/thread/181264
I'm just one person with just one handset, so obviously, I might be an outlier - and your milage may vary drastically. I suspect, however, that I'm not an outlier, and with that in mind, note that (for me, anyway) this update included a Visual Voicemail "upgrade" which auto-enrolled me in a monthly subscription to their ad-free message transcription service. At the end of the free trial, the plan begins to automatically bill at $2.99/month.
Upon unsubscribing, I was given the option to opt out of future auto-enrollment - but I'm fairly confident I've checked that box before...
