Which cellular module do you have in the units? Which operator did you see from serial output when you using hologram sim card?

Which operator did you see from serial output when you using hologram sim card? optus au

I assume you have SIM7600E-H in your units which works on Optus network. I use Optus myself and never had an issue. Please show me the serial output when you use Optus sim cards.

Above is the serial output,

Regarding installation of the sim card & sd card is the same in the guide = https://freematics.com/pages/products/f ... art-guide/

APN: connect

Wondering how is the sd card failing, it's brand new it came with the order?

another round of serial ouput.

SIM card not inserted correctly or you are using a not very proper SIM adapter.

Using a new sim, with the Freematics ONE tracker. that's it.

I'm 100% sure its inserted correctly, like in the guide https://freematics.com/pages/products/f ... art-guide/

Images of how the sim card & sd card is installed
