How to Enable or Disable Cellular Data Roaming in Windows 10
Some Windows 10 devices have a SIM card and/or eSIM in them that lets you connect to a cellular data network (aka: LTE or Broadband), so you can get online in more places by using a cellular signal.
If your Windows 10 device doesn’t have a SIM card or eSIM, you can still connect to a cellular network by plugging in an external cellular device (also called a cellular modem or mobile broadband device). However, these external cellular devices will often have their own settings instead of being able to use the built-in Settings > Network & Internet > Cellular settings in Windows 10.
Users can choose if your cellular data connection stays on when your Windows 10 device is outside your mobile operator's network. Selecting Don't roam will prevent data roaming charges by automatically turning off your cellular data connection when entering a roaming area. If you do allow roaming, you can use cellular data when your Windows 10 device is in a roaming area. Depending on your data plan, you might pay more for data you use when roaming.

This tutorial will show you how to enable or disable cellular data roaming in Windows 10.
If you turn off cellular, you will be disconnected from all cellular data networks.
If you turn on airplane mode, it will automatically turn off all cellular, Wi-Fi, and Bluetooth wireless communication. However, you will still be able to turn on or off your individual Wi-Fi and Bluetooth communications.
You must have a data plan from a mobile operator to connect to a cellular data network.
