I initially had trouble during my free trial and was able to get support on the phone right away. The problem was I needed to keep my son signed into iCloud. After convincing him, I was able to look at his texts. It was awesome. And then it wasn't.
After a few days went by I could no longer get his texts, even the old ones that I already read. The data update button disappeared. I could locate him though, which wasn't that awesome since he is upstairs in his room.
Not wanting to waste my time with customer support, I remembered what fast service I received when I called before. I begrudgingly got my phone hoping for the same. No such luck this time. I listened to some jazzy tune featuring the Xylophone over and over again while on hold for quite awhile. Bored, I happened upon this review site and read that I was not alone in my frustration.
