Microsoft Messaging

Messaging (also known as Microsoft Messaging, and as of recently, Windows Operator Messages) is an instant messaging Universal Windows Platform app for Windows 8.0, Windows 10 and Windows 10 Mobile. The mobile version allows SMS, MMS and RCS messaging. The desktop version is restricted to showing SMS messages sent via Skype, and billing SMS message from an LTE operator.

As of recently, the app was refocused into a SMS data plan app, where your mobile operator sends messages about your data plan, this is due to the functionality of the app switching to Skype. It was also partially renamed to Windows Operator Messages.
