Windows 10 will support sending text messages from your PC, but it seems like it will only work with Android.
Future versions of Windows will include an app called Your Phone, which aims to bring phone features like photos, notifications, and text messaging to the PC. It’s kind of like Pushbullet, but integrated with Windows itself.
Your Phone app works with both Android and iPhone, but one feature only works with Android right now: sending and receiving SMS messages. Here’s Microsoft’s Shilpa Ranganathan, talking to Tom Warren for The Verge:
I want to do this in a supported way with a respect for the ecosystem we’re building on and at the same time make it a delightful experience. Messages is one where we’re not currently where we need to be compared to Android, but we need to work with Apple.
It sounds like Microsoft is hoping Apple will help offer a solution, but I’m skeptical that will happen. Apple’s entire appeal is how tightly integrated their ecosystem is, and you can already send text messages from a Mac using Continuity. Integrating with Windows goes against Apple’s whole strategy, at least as I understand it.
Your Phone isn’t a completely lost cause for iPhone users: notifications and photos will both work. But I’m sure iPhone users would love access to Messages as well.
