I come to you because I have a problem with this module, I can not make it work, the UIFlow method does not work nor arduino. When I give him an AT command I have nothing in return. I don’t understand because I have a NB-IoT SIM card that works.
Can you help me, please?

which M5 core device are you using? M5Stack (Base, Fire, ...) or M5Core2 or M5CoreS3?
Also make sure your SIM card has the PIN disabled.

To read the reply from the module you could use something like this :
