Google Fi is genuinely solid especially for wifi-heavy users that model makes a lot of sense if you're mostly on wifi. The per-GB charging is smart for light users too.Where Infimobile wins for my situation is the annual flat rate. I'm paying $75 for the entire year regardless of usage no per-GB math, no monthly variability. For someone using a consistent 8-10GB monthly Fi could run $50-60/month depending on travel. That's $600-720/year vs $75. The gap is hard to ignore purely on cost .Fi's international coverage is genuinely better though that's a real advantage Infimobile doesn't match. If you travel internationally often Fi probably makes more sense. For domestic only users the prepaid vs postpaid mobile cost difference is significant enough to reconsider.
