SIM7080G can't find any networks.

Beyond this, I checked CBC and it returns somewhere along these values:

0, 2, 3038 ~ lowest
0, 22, 3295 ~ middle
0, 43, 3565 ~ highest

I read that the SIM7080G runs at the minimum of 2.7 V, typical 3.8 V, and maximum of 4.8 V. With the USB connected between the module and my PC, it provides 3.3-3.5 V. Could the power supply be the problem? Because as I said, it’s operating within the rating, however it falls between 2.7 and 3.8, but never 3.8 and beyond.
(2.7 < V < 3.8)
