How to Enable Sync Over Mobile Data in Phone Link for Windows 11
Cellular data syncing in Phone Link lets your Windows 11 PC pull photos, text messages, and app notifications directly from your smartphone without a Wi-Fi connection. By default, Phone Link stops syncing over cellular networks to save your mobile data plan, but Windows 11 version 22H2 and newer lets you turn off this restriction.
You can easily override this setting to keep your devices fully connected when you are away from home and lack access to Wi-Fi .
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?
Field trips or travel often leave you without reliable Wi-Fi , making a cellular fallback essential for keeping messages and photos updated. Maintaining this link prevents missed notifications while working on desktop tasks.
What happens when done?
Turning this on allows your PC to maintain its connection over your cellular network, which consumes a portion of your monthly data plan. Monitoring usage prevents unexpected overage charges from your carrier.

Troubleshooting Phone Link Connectivity Issues
Troubleshooting connection failures starts by reviewing core configurations across both hardware pieces. Check that the Link to Windows app has unrestricted battery usage (meaning the app can use as much battery as it needs), verify identical Microsoft account logins, and confirm storage permissions for contacts and photos.
- 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.
