From an electronic point of view that module would be relatively simple to repair, however if the ESP32 module needs to be replaced then it would need to be reprogrammed. Best ask miEnergi if they will sell you a replacement module.

 

Did you try just reseating the module a few times.
It's been know for laptops to not boot with anything from a CD drive to the HDD itself being the culprit, WiFi cards and RAM which works perfectly well when tested have also been a cause.

I always found reseating everything as the first thing to try is usually worth the time even if it just confirms the first suspicions.

The connecters don't look pristine so reseating might help.

Yeah tried that a few times, it lights up ok without it plugged in. I was going to see if it was able to connect to a hub but probably won't

 

Someone wrote this back in '22

It looks like your board has come lose in transit, and simply needs reinserting back in the GSM slot.

For those who are interested, the module uses an ESP32-VRover module with an external antenna option, it’s a very good choice.

GSM is an interesting nomenclature as that would typically mean it could accept a GSM module aka a Mobile Phone.
