EG912U-GL eSIM EID not returned with AT+QESIM="eid"

IoT Modules LTE Standard Module

Hi,
I am using a Quectel EG912U-GL module with an ST4SIM_200M_VFDFPN8 eSIM. The module works normally with ICCID, IMEI, IMSI, etc., but when I try to query the EID with:

AT+QESIM="eid"

I get the following response:

+QESIM: "eid",8500000A,""
OK

The EID field is empty. Other AT commands for ICCID and network info work fine.

Module Info:

  • Firmware: EG912UGLAAR03A13M08
  • SIM: ST4SIM_200M_VFDFPN8
  • ICCID: 8944477200003118032F

Questions:

  1. Does this module/firmware version support reading EID from this eSIM?
  2. Are there any additional commands or configuration needed to enable EID reading?
  3. Could this be a limitation of the eSIM profile (ST4SIM_200M_VFDFPN8) or firmware?

Any guidance would be appreciated.

That is an SGP.02 eUICC, the LPA should not be able to query it. 6F00 is a generic “reject” command.

What can I do? I urgently need eSIM for my project—can you help me with it?

That is an eSIM (eUICC SGP.02) however it’s tied to some operator so you need to sign a contract with them specifically. Reach out to where you bought the eSIM and ask them which operator it is tied to, then reach out to them to sign a contract, get setup on their platform etc.

If you’re looking for the same eSIM that you have in your phone, that is an SGP.22 eUICC. (Google SGP.22 eUICC and you should find it)

Dear @EMPROTEK ,

Good Day,

Thank You for reaching out to us.

Based on the issue it seems the result code 8500000A in your response indicates an “APDU status error” . This means that while the module attempted to communicate with your eSIM to retrieve the EID, the low-level command (Application Protocol Data Unit) failed or returned an error status from the eSIM chip itself.

1.Does this module/firmware support reading EID?
For Esim, EG912U ,probably requires a specilized firmware for the LPA.

  1. Are additional commands or configurations needed?
    Not realy.But you may check the follwing first.
    SIM Slot Selection: If your hardware uses dual SIM interfaces, ensure the correct slot is selected using AT+QDSIM before querying the EID.

Initialization Status: The error may occur if the module’s kernel hasn’t finished initializing the eSIM stack. You can query the initialization status with AT+QINISTA

  1. Is this a limitation of the eSIM profile or firmware?
    This could be the potential issue, need speciliazed firmware.Could you query your current full version for us, kindly use AT+QGMR command

Thank You!
