How to Enable or Disable Cellular Use in Windows 11
Cellular data in Windows 11 lets your laptop or tablet connect to mobile phone networks using a physical SIM card or a digital eSIM. This mobile internet connection acts as a reliable backup when Wi-Fi is down or out of reach.
Windows 11 switches to your mobile network automatically if your Wi-Fi drops, keeping you online without breaks. You can turn this mobile data feature on or off at any time in your network settings.
Open Settings , go to Network & internet, then Cellular. Toggle “Use cellular whenever Wi-Fi is poor” to On to enable or Off to disable. You may also need a mobile data plan and SIM or eSIM.
How to Check if Your PC Supports Cellular Data
Not all laptops include a built-in cellular modem. Open Device Manager by right-clicking the Start button to check hardware capabilities. Expand the Network adapters section. Look for a device labeled Mobile Broadband, LTE, or 5G to confirm readiness.
Enable or Disable Cellular in Settings
Managing mobile data prevents unexpected carrier charges when Wi-Fi drops out. The Settings app gives total control over whether the PC uses cellular networks.
- Open the Windows Settings app by pressing the Win+I.
- Click on Network & internet in the left-hand menu.
- Click the Cellular tile on the right side of the screen.
- Find the option labeled Use cellular whenever Wi-Fi is poor.
- Toggle the switch to On to enable it, or Off to disable it.
Setting Up Your Mobile Data Plan
Establishing a mobile data plan with a carrier is required before using cellular features on Windows 11. Physical SIM cards and eSIM profiles configure similarly to phone networks.
Enable or Disable via Registry Editor
The Registry Editor offers a direct way to disable cellular features. Administrator privileges are required to make these changes.
- Press the Windows key, type
regedit, and press Enter. - Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WcmSvc\CellularFailover - If the folder is missing, right-click

Troubleshooting Connectivity
Hardware detection failures usually point to an incorrectly seated SIM card. Check APN settings under Cellular > Advanced options to verify carrier requirements. The official Microsoft cellular support page provides additional troubleshooting resources.
Summary
This guide covered hardware checks, eSIM setup, and registry tweaks for enabling cellular data on Windows 11. These steps keep devices online during Wi-Fi outages.
Can I use both Wi-Fi and cellular data at the same time?
Windows 11 maintains both connections simultaneously. Wi-Fi takes priority for data traffic. Cellular data acts as a failover connection when Wi-Fi signals weaken or drop entirely, preserving internet access without manual intervention.
