Database on time to churn in telecomunication I would like to research about time to churn1 in the telecommunication market. Does anyone have a link to such a database? The only ones I found did not include the time of churn, but only if a customer is labeled as churn or non-churn, what I would need is time to event data.

The papers I researched all seemed to use private databases. 

1churn is defined here as the moment in time, where a customer quits the service that he/she book from the service provider.
instead of the database, search dataset
