If you don't see the error message, the only way to tell if someone is actively using Messenger is to look at their status bar. Even if they're on a different call, you may contact them to see if they are available. If they are, the smartphone will ring, and they can choose to pick it up or not.
You can also tell if someone is on Messenger by looking at the time stamp next to their name. If you see a time stamp that says 'active now,' it means they are currently online. If you see a time stamp that says 'active today' or 'active yesterday,' it means they were recently active on Messenger.
