I asked T-Mobile about this...
T-Mobile told me that this was a page from someone leaving you a voicemail message. If you call to check your voicemail options on T-Mobile, there is an option to not allow yourself to be paged. The only weird thing I noticed with this is that whenever I get one of those messages, it never contains any informaton. I started using the visual voice mail and I still get the 129 messages. After some thought I decided to not turn it off, any extra reminders that I have a voice mail are welcome!
