i'm having this problem now too, but in a weird way - i can send but not receive. this is a huge problem, as i need to be able to get 2FA codes to this number...the weird thing is that it was working until today. i moved the router to a new location, but signal seems fine here. speeds still 200-300+ mbps on 5G SA.
did you ever get this working? i'm seeing the exact same symptoms...this worked from the time i first installed the sim until about a week ago, now i can send SMS but can't receive anything. nothing comes through. trying to lock to LTE bands only or 5G NSA don't work either, still can't receive any SMS.
They collected the module logs and have sent them to the manufacturer now. No update yet.. Once they update me I will let you know here..
it seems this may be related to either band locking or removing power from the router to move it to another location.
i normally have the router up at home acting as backup internet for our fios connection, but occasionally take it on trips with me...today after SMS had been working again for a while i moved it to the car for a bit and disabled band masking (as i want it to be able to use all bands while we're on the road), then moved it back to the house...now SMS isn't coming through again. this is the same pattern as the last time this happened, when i was testing the signal at another location in the house. the question is why does it happen when removing power but then all of a sudden start working again after plugged in for an extended period of time?
i've sent the router to tech support, i guess we'll see if they can find anything. it's frustrating and annoying to have this continue to happen, to say the least.
after many research and test by me and GL staff they also accept that SMS working until firmware version 4.4.9. SMS not working with all firmware after 4.4.9.
so, this is problem with GL firmware.
