There is not much difference between 4G Internet Speed Test,and practical speed. Previously I had a 4G Internet Speed network. Its test speed was around 80 Mbps. But when I downloaded something, the speed was about 60–70 Mbps.TMIS, That's not a great difference though. But after the introduction of 5G Speed my practical 4G Internet speed test was the same. if your speed is below 100 Mbps or 50 Mbps then you should opt for a better connection. https://intrenetspeed.livejournal.com/375.html
