[Air-L] DATA ABOUT MOBILE PHONE DIFFUSION

[LEO MAURIZIO]

Dear colleagues,

I am currently looking for some mobile phone diffusion 
data by age ranges in EU countries that start before the 
year 2000. I found information on mobile phone 
diffusion/mobile phone subscriptions, but the data are 
aggregated (not by age ranges).
Do you have an idea of where I could get such data?
Any help would be appreciated.

Kind regards,
