What is the point of information with "probably not"? I don't need information to make a guess. This is a technical device and Digitec wants to sell it. There is only yes or no - everything else is just a waste of time and trouble.

The answer was: You can charge and make phone calls or listen to music at the same time. Unfortunately, I can't answer the other question because a colleague uses the adapter.

But this probably does not work with the modem.
