I have tried multiple sims with the GL-E750 and none work. I get no internet connection. Does anyone know if there is a network compatibility issue with this device or a settings issue? Also it only seems to work with T-Mobile on the US. Verizon doesn’t work and I haven’t tried AT&T. For a Global device cellular compatible seems to be lacking.

Quick update: The error I get is -251 when using the connection wizard with a Smart Telecom sim.

GSM Error Code 251 isn’t standardized ☹  
Do the SIM work when you use them in a phone?

Yes. They work with no issues in 3 generations of iPhones: 10, 12 and 13.

Since I don’t own a Mudi I am just trying to bring light into the dark - so please don’t take me as an expert here:

Would it be possible to set up cellular manually without the connection wizard?
