I've got something similar on a car I bought that was previously leased. I didn't notice it while doing the test drive, but it was almost certainly there the whole time. One day, I'll try to remove it, but afaik, it doesn't do much other than sit there. Maybe it drains the battery a bit, but I think the OEM modem was probably worse... I removed that recently because I was doing work that got me halfway to removal anyway.
