Hello friends, I was using the Verizon on the internal mobile broadband for the Z series of the Sony, and I was using the internet for the past 3 years for the Sony Vaio. I have just moved to the Sony VPC-Z2 and I was using the same internet for it, and suddenly the internet has been moved onto the AT&T, so I bit confuse with it. Does anyone have the problem with the mobile broadband using for the Sony VPC-Z2. So please tell me the solution about it. Thank you.
