GL-M2 No Sim


I have recently purchase a GL-M2 with 5G chip however when connecting it to a Slate AX no matter the sim or settings used I get an error that no sim has been detected and to check it has been inserted correctly which it seems to be. The sim works in any other device I try just not the GL-M2 board

Does anyone know of something I can try or if there is a common fault that can be fixed?

Try another sim card, any network. Preferably NOT THE SAME network but otherwise anything is better than nothing.

Given that a go and no luck, one of the ones tried was actually a Three Mobile sim the same as in their unboxing guide. I have also noticed three parallel lines scuffed on the cards suggesting they have been making good contact.
