Hi, please provide the link to the code or share the code here. Not everyone know the title :)

Not all GSM modem have the same protocol, so it is not compatible.
Also, the crystal is the core to generate baudrate to send data, once that changes, the speed changes, baudrate changes, so it cannot communicate.

I guess sample source code is for you to refer and modify, not plug and play.
