FACEBOOK are trialling new add-on features which could allow users to reply to text messages simply by using the Messenger application.
The social networking site has confirmed that they want to bring back SMS support in Messenger and introduce a multiple account login feature.
The SMS feature, which is currently only available for some Android users, would allow Facebook users to "bring all conversations to one place".
A spokesperson for Facebook told VentureBeat: "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."
Previously Facebook did have SMS integration, but the feature was removed in November 2013.
However, if the add-on takes off this time, there's speculation that WhatsApp, which is owned by Facebook could see the introduction of similar features.
