How to Enable Sync Over Mobile Data in Phone Link for Windows 11
You enable sync over mobile data in Phone Link for Windows 11 to allow your PC to access your phone’s content, such as photos and messages, using your cellular connection. This bypasses the need for a Wi-Fi network, keeping you connected to your device’s data from virtually any location with a mobile signal.
By default, Phone Link prioritizes Wi-Fi to conserve your mobile data allowance. However, you can easily switch this setting on Windows 11, specifically for version 22H2 and newer, to ensure continuous synchronization.
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 really convenient, but it will use up your monthly mobile data. You should monitor your usage to avoid extra charges from your mobile carrier.

Does syncing Phone Link over mobile data consume a lot of battery?
Yes, keeping a constant connection over cellular data requires more power than Wi-Fi. Your phone may drain faster because it must maintain a steady signal to the cellular tower while syncing data to your PC. We recommend keeping a charger nearby if you plan to sync for long periods.
Why is my Phone Link not syncing photos over cellular data?
This is usually caused by background data restrictions. Check your phone’s app settings to ensure “Allow background data usage” is enabled for the Link to Windows app. Also, verify that your mobile data plan is active and not currently in a low-data state or restricted by your carrier.
