At Messenger, we are always trying to create new ways for people to communicate seamlessly with everyone. Right now, we’re testing the ability for people to easily bring all their conversations—from SMS and Messenger—to one place. It’s a really simple way to get, see and respond to all your SMS messages in just one app. By choosing to access your SMS messages in Messenger, they’re right alongside all the other enhanced features that Messenger offers.
The other major tweak, which everyone has access to, is the ability add multiple accounts to Messenger. This should make your life a bit easier if you’re in charge of managing several profiles at once, which is more common as businesses rely on Facebook to interact with customers.
If you want to try your luck with the newest features you can get Facebook Messenger in the Google Play Store.
The story behind the story: Facebook wants to position its Messenger app as the dominant, cross-platform messaging solution. It’s tried to make this happen through integration with other services, like a recent tie-in to Uber and Lyft. Since SMS just won’t die, you could use Messenger for all your conversations this way, unless of course you’ve embraced one of the many other over-the-top services available.
