Searching for a Profile using a Discovery (SM-DS) Server

A Carrier network can place a notification that an eSIM is ready to download on a Discovery (SM-DS) Server. When Windows starts up for the first time, it automatically:

  1. Lists out the common Discovery Servers at the Let’s connect you to a network page.
  2. If an eSIM profile exists, Windows downloads the eSIM Profile and uses the eSIM Profile to connect to the Carrier network.

For more information about how to connect the eSIM profile, see Use an eSIM to get a cellular data connection on your Windows PC.

Follow the steps to search for a profile using the Discovery (SM-DS) Server:

  1. Select Start > Settings > Network & internet > Cellular to check the connection to the Carrier network.
  2. Ensure Cellular is On and Use this SIM for cellular data is set to eSIM.
  3. Scroll down and click eSIM profiles.
  4. Click Add profile.
  5. Select Search for available profiles.
    注:
    • If no profiles are found, a generic error message Something went wrong is shown. While it instructs you to contact your mobile operator, it could also be that you do not have connectivity to the Discovery Server.
    • If a profile is found, then it gets downloaded.
  6. If you have downloaded multiple eSIM profiles, then you must choose which one to use.

    Go to Start > Settings > Network & internet > Cellular and click eSIM profiles.

  7. Select the name of the eSIM profile and click Use.
    注:A message is displayed: This uses cellular data from your data plan and incur charges. Do you want to continue?”
  8. Click Yes to continue.
  9. Select Start > Settings > Network & internet > Cellular to check connection to the Carrier network.
注:A firmware update of the computer's WWAN module may be required to ensure compatibility with the Carrier network. If this happens, you see notification similar to that shown below – Do not reboot, restart, or turn off the computer while the firmware is being downloaded or installed.

Windows is configured by default to use the GSMA Discovery Server that is internationally recognized and independent of any specific Carrier network. Dell Technologies, in addition, configures some additional well-known Discovery servers.

However, some Carriers or private network operators use their own Discovery (SM-DS) Servers, and in such cases, you have to manually change the address.

To manually change the address, go to Start > Settings > Network & internet > Cellular. Then select eSIM Profiles > Default SM-DP server address and then click Edit.

The address can be a DNS name or an IP address. You can also delete the address by clicking the X in the dialog box and click Save .

You then have to manually follow the Steps 1 to 9 to check the new Discovery (SM-DS) server address for an eSIM profile.

注:You can also use Start > Settings > Network & internet > Cellular. Then select eSIM Profiles > Default SM-DP server address to manually search an SM-DP+ for your eSIM profile too.
