Just a heads up, I'm on tmobile's $30 prepaid plan, and I was able to use wifi calling and it didn't use any minutes. I was also able to use google voice as my voicemail. Everything's running good so far.
EDIT: I guess there was a lag on the tmobile website, they did deduct minutes from me. Sorry for posting wrong information! I can confirm google voice working on this plan.
