Germany: Mobile phones increasingly replacing fixed line telephony
A recent review in germany yields the fact that among the group of households with people under the age of 25, 25% use mobile phones exclusively and avoid fixed line telephony completely.
I’m pretty sure this number would be even higher if it were possible to have internet access without having to buy telephony with it. Even DSL is not available without buying telephony as well, and cable is still a futuristic technology in germany (apart from a few select regions).
Adding the tidbit that 50% of those mobile enthusiasts are unemployed, maybe the lack of a credit line is more of a driver than the urge for mobility, though.
