EM05-G eSIM support

IoT Modules LTE Standard Module

I am using a Quectel EM05-G LTE module on an NVIDIA Jetson (Linux) platform.

Module details:

  • Model: EM05-G (global)
  • Firmware: EM05GFAR07A07M1G
  • IMEI: 869283051101303

The module works correctly with a physical SIM, but I am unable to use eSIM features.

During testing:

  • eSIM AT commands (e.g. AT+QESIM? ) return ERROR
  • ModemManager does not detect any eSIM capability

According to the datasheet, EM05-G supports eSIM, so I would like to ask:

  • Is eSIM support enabled only on specific firmware versions? and does firmware EM05GFAR07A07M1G support eSIM?
  • Are special Quectel tools required for eSIM profile installation and management?

Hi,

To further assist you on the eSIM issue, you could do the following:

If possible to access the module physically, please check the OC name:

  • EM05GFA-128-SGNSNE: without built-in eSIM chip
  • EM05GFA-128-SGNS: with built-in eSIM chip

Although the EM05-G supports eSIM in its design, not all physical sub-variants include the necessary eUICC (embedded SIM) chip.
It is possible that the NVIDIA Jetson is using the variant without the built-in eSIM chip

Hello, i confirm you it is the EM05GFA-128-SGNS

Hi dzonit,

Thank you for confirming that the module variant is EM05GFA-128-SGNS, which includes the built-in eSIM (eUICC).

Since the EM05-G module is embedded and supplied as part of the NVIDIA Jetson platform, the eSIM functionality (including eUICC access, profile provisioning, and enablement) can also depend on NVIDIA’s platform integration, such as:

  • Hardware routing and power control for the eUICC

  • BSP / kernel configuration on the Jetson

  • Any platform-level restrictions or customizations applied by NVIDIA

From the Quectel side, the module itself supports eSIM on supported firmware, but we do not have visibility or control over how the module is integrated and initialized on the Jetson carrier/platform.

Therefore, we kindly recommend contacting NVIDIA support to confirm:

  • Whether eSIM functionality is enabled on their Jetson platform
  • If any additional BSP configuration or drivers are required for eSIM access
  • Whether eSIM-related AT commands are supported or restricted in their implementation

Once NVIDIA confirms the platform-level support, we’ll be happy to continue assisting from the module and firmware perspective if needed.

Thank you and have a nice day
