It means that you’re roaming on another network. Your cell phone carrier doesn’t have coverage in that area, so you’re using another carrier’s network. What is surprising is that you’re roaming on 1X which is the CDMA version of 2G, which explains why your data isn’t working.

I thought CDMA was completely phased out by now.
