eSIM (eUICC) usage with RC7630

IoT Modules
1

We are currently evaluating the RC7630 module for an IoT product and would like to clarify the supported options regarding eSIM (eUICC) usage and profile provisioning.

Specifically, we would like to understand the following points:

  1. eUICC Compatibility

    • Is it possible to use an independently purchased eSIM (eUICC) with the RC7630, or

    • Does the RC7630 require an eSIM provided or approved by Semtech/Sierra Wireless?

  2. Profile Provisioning Method

    • If a third-party eUICC is supported, can profiles be downloaded via GSMA IoT RSP (SGP.02) using an SM-DP+ server?

    • Are there any restrictions on SM-DP+ providers or eUICC vendors that can be used?

  3. LPA Support

    • Does the RC7630 firmware include a Local Profile Assistant (LPA) for eSIM profile download and management?

    • If so, is the LPA enabled by default, or does it require a specific SKU, firmware option, or license?

  4. Download vs. Activation Control

    • Is it possible to download a profile without immediately enabling or activating it (i.e., download-only, activate later)?

    • What event typically triggers billing/activation (profile download, enable, or first network attach)?

  5. Recommended Approach

    • For production deployments, do you recommend:

      • using a Semtech-provided eSIM,

      • selecting from a list of approved eUICC vendors, or

      • another provisioning approach?

Our intent is to determine whether we can source eSIMs independently, or if we should rely on vendor-supplied or vendor-approved eSIM solutions to ensure full compatibility and GSMA compliance.

Some discussion regarding internal esim of rc76

If you use your own eSIM, you might need to get a tool from distributor to disable the internal LPA inside module stack so that you can run your own external LPA on host platform

Based on your explanation, I would like to clarify the LPA architecture in more detail.

If the LPA is implemented externally (for example, on a Linux host OS or a PC application),
is it technically supported to:

• Run the LPA logic (SM-DP+ communication, profile management) outside the modem
• And then use AT commands or QMI only as a transport channel to send APDUs / profile data to the eUICC inside the RC7630?

In other words,
can the modem act purely as an APDU tunnel to the eUICC,
while the full LPA (per GSMA SGP.02 / SGP.32) runs on an external host?

Or is the LPA required to be integrated inside the modem firmware and tightly coupled with the eUICC interface, making an external LPA + AT/QMI approach unsupported?

Any clarification on the supported architecture would be appreciated.

I think the lpa can be run in external host platform and controlled by AT command
