Microsoft Phone Link App for Windows: What It Does

The Microsoft Phone Link app (formerly known as “Your Phone”) is a built-in Windows utility that connects your Android phone or iPhone to your PC, letting you view notifications, send texts, make calls, see photos, and even run mobile apps directly from your desktop. You set it up by pairing your phone with your Windows PC via Bluetooth and Wi-Fi, and after a one-time QR code scan, the two devices stay in sync. This article explains exactly what Phone Link does, how it works, what you need to use it, and where it falls short.

Background: From “Your Phone” to “Phone Link”

Microsoft introduced the “Your Phone” app with Windows 10 in 2018 as a way to bridge the gap between Android phones and Windows PCs. The original version only mirrored notifications and allowed photo transfer. Over time, Microsoft added messaging, calling, and screen mirroring. In 2022, the app was renamed “Phone Link” to match the companion app on Android, which is called “Link to Windows.” The iPhone version, which arrived later, is more limited because Apple restricts deep system access. The name change also reflected a shift in focus: instead of just mirroring your phone, the app now aims to make the phone and PC feel like one workspace.

What Phone Link Actually Does

Phone Link is not a remote desktop tool—it’s a synchronization and mirroring service. Here’s what you can do with it:

Send and receive text messages from your PC, using your phone’s number and cellular connection.
View and dismiss notifications from your phone on your PC, including app alerts and calendar reminders.
Make and receive calls through your PC’s microphone and speakers, with your phone acting as the relay.
See recent photos from your phone’s gallery and drag them into documents or emails.
Mirror your Android screen and interact with any app on your phone using your mouse and keyboard (Android only).
Use mobile apps side-by-side with Windows apps, thanks to a feature called “Apps” that lets you pin Android apps to the taskbar.
Copy and paste text and images between your phone and PC, as long as both devices are signed into the same Microsoft account.

For iPhone users, Phone Link supports messaging (via iMessage), notifications, and calls, but not screen mirroring or app access. That’s because Apple doesn’t allow third-party apps to access the iOS screen or run background processes as freely as Android does.

How Phone Link Works: The Technical Side

Phone Link relies on a combination of Bluetooth, Wi-Fi, and Microsoft’s cloud services. When you first set it up, you scan a QR code on your PC screen with your phone’s camera. That code links the two devices through your Microsoft account and establishes an encrypted connection. After that, the app uses Bluetooth for low-power tasks like detecting proximity and sending notifications, and Wi-Fi for data-heavy tasks like photo transfer and screen mirroring.

The Android companion app, “Link to Windows,” is pre-installed on many Samsung, Honor, and Surface Duo devices. On other Android phones, you download it from the Google Play Store. The app runs in the background and sends data to the Phone Link app on Windows. For the connection to stay active, both devices need to be on the same Wi-Fi network, or at least have internet access. Bluetooth must be enabled on both devices, and the Phone Link app must be allowed to run in the background.

One important detail: Phone Link does not use your phone’s data plan for the connection. It uses your home or office Wi-Fi, or your PC’s internet connection. If your PC is offline, the app won’t work, even if your phone has cellular data.

System Requirements and How to Set It Up

Before you install Phone Link, check that your devices meet the minimum requirements:

Windows 10 or Windows 11 (the app is pre-installed on Windows 11, but on Windows 10 you may need to download it from the Microsoft Store).
Android 7.0 or later, or iOS 14 or later for iPhone.
Bluetooth 4.0 or later on both devices.
Both devices signed into the same Microsoft account.
Phone Link app on Windows and Link to Windows on Android (or the built-in iOS integration).

To set it up:

Open the Phone Link app on your PC (search for “Phone Link” in the Start menu).
Click “Get started” and sign in with your Microsoft account if prompted.
On your phone, open the Link to Windows app (or go to Settings > Connected devices > Link to Windows on Samsung devices).
Scan the QR code displayed on your PC screen with your phone’s camera.
Follow the on-screen prompts to grant permissions: notifications, contacts, phone calls, and media access.
Once paired, you’ll see your phone’s status in the Phone Link window.

If you have an iPhone, the setup is similar, but you’ll use the built-in iOS integration: go to Settings > Phone on your iPhone, then tap “Link to Windows” and scan the QR code. The iPhone version does not require a separate app.

Common Problems and How to Fix Them

Phone Link is generally reliable, but users often run into a few recurring issues:

“Phone not connected” error: This usually means Bluetooth is off, or the devices are out of range. Turn Bluetooth off and on, and make sure both devices are within 10 meters (33 feet) of each other.
Notifications not appearing: Check that the Link to Windows app has notification access on your phone (Android: Settings > Apps > Link to Windows > Notifications). Also, make sure “Notifications” is enabled in the Phone Link settings on your PC.
Messages won’t send: Phone Link sends texts through your phone’s SMS service, so your phone must have cellular service. If your phone is in airplane mode, messages will fail.
Screen mirroring is laggy: Screen mirroring requires a strong Wi-Fi connection. Move closer to your router, or switch to a 5 GHz band if your router supports it.
App doesn’t open on Windows 10: The app may not be pre-installed. Download it from the Microsoft Store, and make sure Windows is updated.

If you’ve tried all these and still have issues, sign out of both devices and sign back in. This often clears authentication glitches.

Privacy and Security Considerations

Because Phone Link has access to your texts, calls, and photos, it’s worth understanding the privacy implications. The connection between your phone and PC is encrypted, and Microsoft states that it doesn’t use your data for advertising. However, the app does sync data through Microsoft’s servers, so your messages and notifications pass through Microsoft’s cloud. If you’re concerned, you can limit what Phone Link can access: in the app settings, you can turn off notifications, messages, or photo sync individually. You can also unlink your phone at any time by going to Phone Link settings and clicking “Unlink.”

One common misconception is that Phone Link gives Microsoft access to your phone’s files. It doesn’t—the app only sees the specific data types you grant it permission to access, and it can’t browse your phone’s storage. Also, the app doesn’t work when your PC is locked, so someone with physical access to your PC can’t read your texts unless they log in.

Alternatives to Phone Link

Phone Link is not the only way to connect your phone to your PC. Here are a few alternatives, each with its own strengths:

Dell Mobile Connect: Similar to Phone Link, but designed for Dell PCs. It offers the same features but is limited to Dell hardware.
Intel Unison: A newer app that works on Intel Evo laptops, offering file transfer and screen mirroring for both Android and iPhone.
AirDroid: A third-party app that lets you manage your Android phone from a web browser or desktop app. It supports file transfer, remote control, and screen mirroring, but the free version has data limits.
KDE Connect: An open-source option that works across platforms, including Linux. It offers file sharing, remote input, and notification sync, but the user interface is less polished.
Pushbullet: Focuses on notification mirroring and file sharing, but doesn’t support calls or screen mirroring.

For most users, Phone Link is the best option because it’s free, built into Windows, and integrates deeply with the operating system. The alternatives are worth considering if you need cross-platform support (like Linux) or if you have a Dell PC and want a more optimized experience.

Frequently Asked Questions

Is Phone Link free?

Yes, Phone Link is completely free. It comes pre-installed on Windows 11, and the Android companion app is free on the Google Play Store. There are no subscription fees or in-app purchases.

Does Phone Link work with iPhones?

Yes, but with limitations. iPhone users can send and receive iMessages, see notifications, and make calls through Phone Link. However, screen mirroring and app access are not available on iOS because Apple restricts those features.

Can I use Phone Link without Wi-Fi?

No. Phone Link requires an internet connection on your PC, and for most features, both devices need to be on the same Wi-Fi network. Bluetooth alone is not enough for data transfer.

Will Phone Link drain my phone’s battery?

It can, especially if you have screen mirroring or frequent notifications enabled. The Link to Windows app runs in the background, and constant Bluetooth and Wi-Fi usage will use some battery. You can reduce battery drain by turning off features you don’t use.

Can I unlink my phone from Phone Link?

Yes. On your PC, open Phone Link, go to Settings, and click “Unlink.” On your phone, you can also go to Link to Windows settings and sign out. This stops all syncing between the two devices.

Does Phone Link work on Windows 10?

Yes, Phone Link is available on Windows 10, but you may need to download it from the Microsoft Store if it’s not pre-installed. Microsoft has stated that Phone Link will continue to receive updates on Windows 10 until support ends in October 2025.
