Looking from a non EU country I still see some advantages of international cards such as UM or Travelsim: they allow free incoming calls with the outgoing tariff similar to the rates quoted in the beginning of this topic. Thus, for us (outlanders
) it will be always better to pick an international card than a EU 'normal' card. The advantage for EU citizens is that they will be able to keep their number paying few money for incoming calls (which is often more reasonable than forcing your friends or relatives to call for 20-40 cents/min or more a foreign mobile number that your international card has). So, international cards will be existing for the rest of the world, at least.
