[1st-mile-nm] T-Mobile

I believe my relatively inexpensive moto g5s plus supports 700 MHz B12, but
not 600 MHz B71. The nearest cell tower came online within the past year.
But, my phone was never able to talk to it until today.

Is there a good app that reports on the frequency capabilities of the phone
it's running on and the tower it's talking to?

I've found one called kimovil, but I believe it reports published specs not
diagnostic data from the phone.

“If this were my country,” Odile said, wrinkling her nose, “I would not be
angry.”

“No?” Hollis asked.

“I would drink all the time. Take pill. Anything.”
