Are there any provisioning steps required to begin using the EHS5-US with a SIM Card installed? | Thales IoT Developer Community

Modules

In our application, the SIM card is installed at assembly but it is NOT activated with our MVNO. Once our product is shipped, the user enters in some information to our website which then sends a command to our MVNO to activate the SIM card. (Q1)Once the SIM card is activated - are there any AT commands required to be sent to the module before we can begin using data connections? I am aware that we must wait for the PBReady to be displayed, but that happens automatically. I have a concept board, and I was able to simply activate the SIM card using my MVNO's portal. After inserting the SIM card and waiting for PBReady, everything simply started working (I was able to send text messages and establish data conenctions). (Q2) Is this the correct procedure and can this be repeated in mass production?

Hi, A1) Of course you should provide APN etc to have data connections working. Besides that no special activation procedure are needed. However consider following scenario: - starting module with not activated SIM card - network rejects the module - SIM card activation by MVNO operator In such case the module will not register untill rebooted. A2) This procedure should work, however take above scenario into consideration. Just to clarify - you get +PBREADY informing that the SIM has been read and phonebooks has been scanned. It doesn't mean that the module is registered to the network. Regards Jedrzej

Hi, I guest the described steps are rigth. If the module start up and the SIM is not provisioned the HLR of the carrier will not accept the subcription in the network. You can observe this case with AT+COPS? and the answer will show 3 Operator forbidden Or with at^moni --> Limited services in your home carrier In this case you need to wait until the subcription will be activated and reset the SIM interface with AT+CFUN=1,1 or just reset the module. Under my experience the time beetwen the activation in the software tool to allow this subcription in the network can take some seconds until some hours. It's depend of the carrier Regards ALopez
