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.

Hi @mackzswe ,

I’m currently working with the ST4SIM-300M as well and I noticed that I’m getting exactly the same ICCID:

89019990001234567893

From what I understand now, this seems to be a placeholder ICCID and the eSIM does not have a real preloaded profile.

I wanted to ask if you were able to make progress with this setup. Did you manage to download a profile or get the eSIM working with any provider?

Any insights from your side would be really helpful.

Thanks in advance!

Hi @saharhaghdadi 
We have not been able to progress any further since we are working with the nrf9160 chip which we have since discovered does not support communicating with SIMs without an active profile.

thank you for your fast respond @mackzswe

Hello, is there any news on the activation of the st4sim-300m? Is it correct that there is no bootstrap profile on it and the activation code from the operator does not activate this esim?
