I have a very peculiar situation. A few weeks ago I called Verizon's prepaid department and started the process of getting month to month 4G data on my Xoom. When it came to the activation step on the xooms end, it kept coming up as already activated but wouldn't let me access any other page besides the activation page. The VZW rep said there was nothing else she could do for me. About a week later I was swapping the 4G sim card from my HTC Rezound into the Xoom and vice versa. Just for kicks, I powered on my rezound and to my surprise I was getting access to data on it with the xooms sim. Seeing as how the sim works in my phone and not the tablet, I figure that there must be some way to change the APN settings on the Xoom to mimic my phones. Does anyone have any suggestions?
