Cellular/SIM connection not available/disappearing

Hi,

A faulty cellular adapter is one of the possible reasons why the cellular connection is disappearing from the laptop. A disabled adapter in the Network Connections Settings can also be the cause of this issue. We suggest you to enable the cellular connection
in the Network Connections settings. You can follow the steps below:

• Press the Windows key.
• Type View Network Connections.
• Press the Enter key.
• Right-click on the cellular adapter and click Enable.

Should you need further assistance, don't hesitate to get back to us.

 

Manage cellular connections - choose roaming operator

Hi
Is there any way to manage cellular connections (mobile broadband) better in Windows 10? I would like to be able to see available operators and choose to which to connect. Maybe there is an app that gives you that level of control?
Thanks for any suggestions.

 

Cellular/SIM connection not available/disappearing

Hello Eric,

This problem has appeared again and I tried this but the cellular adapter was already enabled. The system still indicated there was no connection. This is the third Verizon SIM card we've sent to this user and I confirmed the card is active and there's nothing
wrong with our Verizon account. Also, it was working for a while the other day and then recently stopped again. It appears as if the laptop randomly stops detecting the card. This has happened to at least two other users over the past month as well. But for
this one user in particular, it seems to be an ongoing problem.

Hi,

Just to check, are you still having issues with your cellular/sim connection?

We're looking forward to your reply.

Hello,

Yes. The cellular adapter seems to disappear often.

Thank you for your reply.

Given that the network connection settings is properly configured and there's no problem with your internet service provider, it seems that the network adapter itself is having an issue. In this case, we suggest contacting the device manufacturer for a hardware
checking.

Please post back if you have any Windows concerns for further assistance.
