ST4SIM-300M Getting the same ICCID

[mackzswe]

Hi! We have two custom boards that we have soldered the ST4SIM-300M eSim to. We have earlier been using the ST4SIM-200M and followed this activiation procedure:

https://www.st.com/resource/en/application_note/an5740-st4sim-with-truphone-connectivity--activation-procedure-stmicroelectronics.pdf

to get them working with truphone.

Now when i try to do the same thing with our new eSim i get the same ICCID from both, this is what i get:

at AT%XICCID 

%XICCID: 89019990001234567893

When i try to enter it on truphones activation page it says that the device is not found.

Am i doing something wrong or missing anything?

Hello Mackzswe,
The current ST4SIM-300M sample does not have any real preloaded profile like Truphone; it is empty. The ICCID you read has been set to satisfy some cellular modules that reject the eSIM if no profile is preloaded.
