An issue I have with trams is that they are very slow if not properly integrated in both the city layout and the general population of the city. For example, in Marseille, trams have to frequently compete with pedestrians and bicycles that keep walking/riding on the tram line. This doesn't happen with buses (or not as frequently).
The one thing that makes them better than buses in Marseille is that trams are more reliable time-wise since they don't have to share the road with cars.

More seriously, in these cases, I often rely on emails instead. But I don't really use group chats a lot (even with my contacts that are on Signal), nor send many files, so it's not features I really miss. And SMS works with everyone, so it's always my default if the contact isn't on Signal.
