Don't know why. But, my MB is slower than my phone. Phone gets up to 12Mbps in house. Although that is standing in a couple of spots. Other places can get up to 7. In general service is in and out depending on where I am in house. Magic box doesn't connect in the good spots. So, I get a steady 4 everywhere.
noticed 10x10 2nd carrier in multiple subway stations. Also noticed it a few times around manhattan. One thing i noticed is that my phone will not do CA with the 10x10 and 5x5 carrier. But on site that haven't been updated to 10x10 the phone still does CA
