Hi,
We are evaluating the EG800 as a replacement for the currently used lte-m in our products. I’m using the evaluation board (EG800QEULC-N03-TA0AA) with motherboard (UMTS<EEVB-Kit) and everything went fine.
All of the sudden the SIM card is not functioning anymore but the card is working in other modules. If I check the VDD on the sim card holder then I see that the voltage is not there.
Is there any setting for this? Did I changed something accidentally? Are there schematics of that motherboard.
I also noticed that some SIM cards were working flawlessly and others needed several power cycles to start, before everything started to fail.
This is a kind of a show stopper.
