I've been working with one of these shields... SIM7600CE-T_4G(LTE)_Shield_V1.0_SKU_TEL0124-DFRobot In particular the module is receiving an SMS... but I don't seem to be able to display the whole message on the Arduino. I've cut it back to a very basic sketch as follows #include <SoftwareSerial.h>…

SoftwareSerial is very unnlikely to operate at 57600 with any other activity on the processor. I'd be surprised if it was any good over 19200 or even 9600 in most applications. Get a MEGA or other processor which has multiple hardware serial ports, Problem solved

Yup, the ESP will be much better, but I wouldn’t trust SS with anything over 19200 on any hardware.

Plus, it just eats cpu cycles for no benefit.
