Fortunately, there is a way of knowing the exact number of decibels (dB) you're getting, for a more precise reading. More bars do usually mean more signal, but there’s no real standard. It's totally arbitrary, and this is true for both 5G and 4G. One bar on AT&T could mean full bars on T-Mobile, which could be two bars on Verizon.
