How to Enable Sync Over Mobile Data in Phone Link for Windows 11
Phone Link sync over mobile data lets your PC use your phone’s cellular data to access your phone’s content, like photos and messages. This means you can stay connected to your phone’s information anywhere you have a cell signal, without needing Wi-Fi.
By default, Phone Link only syncs when your PC is on Wi-Fi to save your mobile data. However, you can change this setting in Windows 11, starting with version 22H2.
This change ensures your phone and PC stay in sync even when you’re not near a Wi-Fi network.
Open Phone Link on your PC, go to Settings (gear icon), select General, and toggle “Allow my app to sync over mobile data” to On. Ensure “Allow background data usage” is enabled for Link to Windows on your phone.
Why use this feature?
Why would you use this feature? Imagine you’re at a park or traveling, and there’s no reliable Wi-Fi. This setting keeps your messages, photos, and apps synced between your devices. That way, you won’t miss an important notification while you’re working on your PC.
What happens when done?
Your PC will start using your phone’s cellular data to keep the connection alive. This is convenient, but it does use your monthly mobile data. Keep an eye on your usage to avoid extra charges from your mobile carrier.

Troubleshooting Phone Link Connectivity Issues
If your Phone Link mobile data sync isn’t working, the first step is to check common settings on both your phone and computer. Make sure the Link to Windows app has unrestricted battery usage (meaning the app can use as much battery as it needs), you’re signed into the same Microsoft account on both devices, and that the app has permission to access your phone’s photos and contacts.
- Battery Optimization: Go to your phone settings and set Link to Windows to “Unrestricted” battery usage.
- Microsoft Account: Ensure you are signed into the same account on both devices.
- Permissions: Verify that the app has permission to access photos and contacts.
