I know that Port Fowarding and Firewalls can cause issues and confusion, so I've written the below instuctions to try and help.
UDP PORT 9988 STILL NEEDS TO BE OPENED IN YOUR ROUTER FOR SIMCOM X TO WORK CORRECTLY. is the best site I know of, with instructions on how to forward a port in your specific router.

The below instructions only show how to remove the Simcom X Server from the Windows 10 Defender firewall and then add it again.
This is incase you weren't sure if you'd added it correctly the first time.
The instructions should be SIMILAR for most firewalls.
