The latest Windows 10 Mobile Insider Preview update features an app called “Messaging Everywhere” that lets you send and receive cellular text messages from a Windows 10 PC.
To enable this:
- Make sure you are signed in with your Microsoft Account (MSA).
- On your phone – make sure “Send texts on all my Windows devices” is turned on.
- On your PC – make sure you have chosen which phone to send messages through. You do this in the settings of the Messaging app on your PC (screenshot below).
