Roughly how much data does Mass Effect 3 multiplayer use, assuming that I use voice chat? Is it even possible to get a reasonable estimate for this?
That is hard to tell as it's dependent on
- Number of players
- Number of mods or extensions running on the server
- Location of the Server
Generally, You could test it by
- Resetting the data counter (via the system or a third-party app)
- Play for a specified amount of time
- Check the data used
This number should give you a rough idea, if it is worth to you spending your data on it or not.
