After ten years of using AT&T, I switched to Google Fi and here are my thoughts. Before I start my review, here’re some details you might be interested in. I use Google Fi on an unlocked iPhone XS. I knew very well about the limitations before I signed up for the service. So, here is my review of Google Fi on iPhone.
I’ve been a Google Voice (GV) user since the past ten years. I love the service. I’ve used it for my voicemail and for making international calls to India. I liked the voicemail transcription feature too. This is a pretty common feature now, but, GV pioneered it.
Anyway, I was able to sign up for Google Fi online from this page here https://fi.google.com/signup and apply for the SIM card installation kit.
