PINE64

The other thread was closed before I had a chance to respond, so I'm just going to leave this here instead.
This works on the PinePhone Pro (Explorer). I have not tested on other devices. This works on the Quectel EG25-G modem.

FYI, I'm using Mobian, so you have to stop the modem-manager first or it will cause a conflict with minicom (terminal suddenly stops responding).
This feature is NOT documented in the PDF from Quectel, but it still works.

In a console:

Code:
systemctl stop ModemManager.service

Now you can run minicom without it hanging.

Code:
minicom -b 115200 -D /dev/ttyUSB2

Inside minicom, to get your current IMEI:

Code:
AT+CGSN

860195057712345

To change your IMEI:

Code:
AT+EGMR=1,7,"860195057754321"

OK

You can confirm it changed by running:

Code:
AT+CGSN

860195057754321

That's it.
