I have to admit, this article did make me wonder if there were any other substantive differences between these modems. I had no clue, before seeing this article, that only the QUALCOMM modems supported all of the different network types. I have no interest in going back to Verizon, so for me personally, it probably doesn't matter. On the other hand, what else is hidden? Mary
