We analyze a very large Call Detail Records (CDR) over 12 months in Mexico. It contains 8 millions users ans 5 billions of call events. Our first contribution is the study call duration and inter-arrival time parameters. Then, we assess user movements between consecutive calls (switching from a station to another one). Our study suggests that user mobility is pretty dependent on user activity. Furthermore, we show properties of the inter-call mobility by making a analysis of the call distribution
