There seems to be a lack of communication between the one X and the microcell. All three other phones connect no problem (2 Galaxy S3s and a note) but the one x don't see it, or vice versa. I powered both down and rebooted and same thing. I tried to go online to AT&T to add the One X to approved numbers but 1) I should not have to do this? and 2) When trying to register the tower, it says unable to because its already registered to another customer? What? It was brand new when I bought the thing from AT&T. So, calling AT&T (they are probably out until friday, so I thought I would throw this out here and see if anyone else had this issue.
