Q: Do I have to use Skylight to manage the 4G Connection?

A: No it is not required as Windows can manage the connection just fine. Here are some steps when installing the drive that will help:

• Download Latest Driver from our driver page for your model
• Unzip the driver
• Right Click configuration file and go to properties
• Uncheck read-only if it is checked then hit OK
• Open Configuration file
• Change FWUpdate=OFF to FWUpdate=Auto (Updates 4G card firmware to the latest)
• Change AUTOFWSIMMATCH=0 to AUTOFWSIMMATCH=1 (Changes Carrier Firmware based on SIM)
• Save changes and Exit
• Make sure you're still on the internet for 4G Card firmware to download and install
• Run Driver Setup file that is in the same folder with the configuration file
• Walk through default steps of installing driver

This will allow you to have the driver installed without using skylight and the proper carrier will be chosen based on your SIM. Now you can manage the connection through Windows.
