Hello,

After purchased a  B-L462E-CELL1 and find ICCID and active on Truphone....
below is my tera term output

I want to configure this board in STMCubeIDE  but I'm very new to this  ( I tried send AT command manually but I didn't get any response )
I also tried to install X-CUBE-CELLULAR in STMCubeIDE   but It's showing error (refer attached image)

Can anyone help me on this ?

Hello @Mayank2 ,

Try follow the steps in this FAQ: How to install and import an X-CUBE Expansion Pack... - STMicroelectronics Community

Hello @Imen.D 

I attempted the approach you provided, but I'm still unable to integrate the X-Cube-Cellular packages into my project. For the error, see the screenshot attached.

This board is what I intend to use to carry out AT commands. I've tried using the "Tera term" for that as well. However, the AT command is not receiving any answer. I don't understand the processes involved in board configuration. Could you please assist with configuring this board and sending the AT command ?

'Registration Denied' means that the Network specifically refused to allow the device to register.

This means that your device is successfully communicating with the Network, but the Network is refusing to register it.

So there is some problem with your subscription - you would need to talk to the Service Provider (Truphone?) about that...

Hello,
I want to configure my already existing phone eSim with this board. So, Can I ? If yes, then can you please help me to configure eSim.

[Andrew Neil]

An eSIM is a hardware chip embedded in the phone - you can't take it out and put it into a different device.

Whether your service provider will allow you to transfer your credentials from your phone to another device is something you would have to discuss with the service provider. However, almost certainly, a subscription for telephone service won't be transferrable to an embedded data-only device - especially for LTE-M/NB-IoT
