Windows用SIM/eSIMセットアップ ガイド

Cellular signal shows connected but no Internet access

If your cellular signal shows as connected but you have no Internet access, here are some steps that you can take to troubleshoot the issue:

• Ensure that you have an active subscription with your Carrier network. If your SIM or eSIM provides a link to the Carrier network account settings, you can check your subscription status as follows: Go to Start > Settings > Network & internet > Cellular.
• Select Connection settings > View my account.
  注:If you see the message Connect with a data plan, it indicates that you do not have an active subscription.
• Alternatively, you can call, message, or check the Carrier network website.
• There is a possibility that the Mobile Carrier Access Point Name (APN) that is necessary for connecting to the Internet over the Carrier network rather than the cellular radio network is not recognized by Windows. This issue frequently occurs with Private 5G networks and some Mobile Virtual Network Operators (MVNOs) that use eSIM but are not part of Microsoft Windows Mobile Plans.
• To add the APN manually, go to Start > Settings > Network & internet > Cellular, select Mobile operator settings and click Add APN.

  Contact your Carrier network, search their website, or search the web for APN Settings to obtain the necessary APN, username (if required), password (if required), and type of sign-in information (if needed), otherwise choose None.

  Choose the Profile name, and ensure that the APN type is set to Internet and attach.
