The landline systems in most European countries are way better than in the US. As a result of intensive investments after reunification especially Germany has one of the most advanced telecommunication systems in the world. 100% of German switches are digital and as you can see below we have the highest ISDN penetration in the world and also ADSL is available to 92% of German households (most of the remaining 8% can't get ADSL as they are conencted through optic fibres):

Switzerland, Austria, the Benelux countries and Northern Europe have comparable developed landline networks.
In the US only the highly populated areas have modern landline infrastructure - in other areas the system is ramshackle. That's why cable internet is so wide spread in the US.
So maybe in Southern and Eastern Europe people use mobile phones because of the lacking landline availabilty, but certainly not in the Northern countries.
However we should get back to topic.

Another test in Poland. As of today UM+ (outgoing calls) doesn't work with Era - the callback connection is broken after one second ringing or no ringing occurs at all. After the failed callback, the first the message "Calling" followed by number dialed dispalys for a few second and the whole thing ends with "Service unavailable" message and a single "OK" option to close that message.

Caller ID is rather unstable both ways and more often it doesn't display.

Edit:
SMSes from Era to UM+ don't go through. I said before that they went OK but I realised that I had forgotten to test the Era->UM+
case. So the conclusion is that UM+ roaming on Era network works for incoming calls/SMSes only

all I need to say about this is, who cares about ISDN. ISDN is such an old implimentation of broadband, or ip technology and is often erroneous in describing broadband connectivy. Germany has actually been lagging the EU for BB uptake for the past three years. Granted, 2 years ago they had a 10% penetration, but today it is only 15% at best. UK is now close to 25% and the Scandinavian countries are 30%+. US has been 20%+ for the past three years But ISDN, it sure ain't the future. As for the data, this data is AT LEAST three years old, FOTH, DSL, cable, wimax and EOP have all made huge changes in places like north america, where it will TRULY be fiber to the home.
