I’ve been on Google Fi for 3 or 4 years and it’s been pretty much flawless. I’ve traveled to Mexico and Spain with it, and there’s a sort of calibration period of like 30 minutes before you have service in another country, but that’s literally the only time I’ve been without service for any period of time. My wife and I are on it and use very little data, so covering both phones is typically about $60/month. We usually have 5G service around our home in northern VA.
