see signal-to-noise…

You can still do that. It’s called a “field test”. From your phone app dial

*3001#12345#*

And it’ll bring up a menu of all that information. I used to use it a lot back in the Nokia 2G days and it’s still around.

My issue though isn’t signal strength to the tower. That is good and would show as much. My issue ends up from the tower to the telco is so saturated you can’t get anything effective. It’s like being connected to your WiFi, but your gateway is offline.
