This information is expressed as a percentage and can therefore exceed 100% if the number of SIM cards in the country is higher than the actual human population.
For example, by this measure, Hong Kong has a mobile phone penetration rate of 291% – the highest in the world in 2021.
A more accurate way of measuring how many people in a particular country have a mobile phone is using the stat Unique Subscriber Penetration which is the total number of people in a country that own a mobile phone expressed as a percentage of the total population. This can therefore never be greater than 100%.
