This service used to be fairly accurate years ago but I guess someone is paying them off now because even when my Internet is so slow I struggle to load web pages which happened with my previous carrier visible and now is happening again with cricket but ookla speedtest shows 15mbps and my last test showed 40mbps and that's absolutely impossible considering my Internet is slower than 256kbps and with visible my Internet got so bad it took over 5 minutes to load web pages and it wasn't even worth using because it was just too slow and speedtest showed 25mbps so either they need to fix their service or they need to stop working for the phone carriers there's something fishy about this service now
