Note on Subscriber Accounting Policies

The number of subscribers mentioned in our reports effectively 
means number of valid SIM-cards as reported by mobile operators 
according to their churn policy.

Cellular service penetration figures are calculated based on official data 
reported by state statistics institutions of respective countries.

Cellular service penetration in Russia and Ukraine 
is above 100% which means that operators combined have more active 
subscribers (valid SIM cards) than the number of population.

The "real" or "human" penetration means a number of people who use 
cellular service divided by the total population of the respective 
country or region.

Although AC&M have estimations on the subject and conduct regular 
end-user survey to measure human penetration, we do not publish 
this information as it is always a subject for additional research. 
Moreover, the correlation between human penetration and number of active 
user accounts differs from region to region.

If you are interested in more information on any particular 
region please do not hesitate to contant us at
