No one knows.
Presumably this is a USB device you are talking about? Something like This?
Take your modem into someplace that sells the Acer, and plug it in to a demo unit and test it out.
If your modem has drivers that need to be installed, I doubt it will work.
Yes thats exactly what I'm talking about, but the prb is, there is no retail shop for acer that sell iconia A500 in my country, I'm going to import one.
Well, I don't think anyone would be able to tell for sure without having one of those modems
in hand to test with.
I have a standard USB dial-up modem, and the Acer had no clue what to do with it.
Even watching the log with aLogCat showed no activity when I plugged in this modem.
