Thankfully, Google has updated it Messages app to finally include free and unlimited texting from your PC. Here’s how to use it:
Make sure you’ve updated to the latest version of Android Messages and open it on your phone. It’s pre-installed on many devices, but you can download it from the Play Store if you don’t have it. You’ll also need to set it as your default SMS app for full functionality.
Tap the three-dot Menu in the upper-right corner of Messages and choose Messages for web. If you don’t see this yet, you’ll need to wait for the update to roll out to you.
If you want to stay signed in, enable the Remember this device slider. Then tap Scan QR code on your phone, and use your device’s camera to scan the code on your PC screen.
Once it completes, your latest conversations will appear on your PC. Google says that they’re encrypted and cached in your browser. If you don’t access this for 14 days, Google will automatically sign you out for security.
If you want to use a dark theme on the website, open Menu > Settings > Enable dark theme.
You can pair with multiple computers, but only your current one will be active at a time. And since this goes through your phone, it won’t work when your phone is off.
For convenience, you can use Chrome to create a pseudo-app for this on your PC. While on the Messages page, go to Menu > More tools > Create shortcut. Give it a name and check Open as window to add a link to it on your Taskbar. Then you can access your messages in a dedicated window.
