This is contradictory. This is like me saying I have never paid to get into a movie. Because I buy the ticket and then get into the movie for free. So you pay for a plan which includes X minutes and those X minutes are free? How are they “free”?
The whole point is that in Europe received calls are free as in really, truly, free. They do not count in any way, shape or form. You can have a pay-as-you-go phone with a balance of 1 euro and if you make no calls but receive calls all the time, three months later your balance is still 1 euro.
In Europe the philosophy seems to be that whoever makes the phone call pays for it and mobile phones have different prefixes so the caller knows he is making a call to a mobile phone and will pay for it.
In America the philosophy seems to be that the user has a cell phone for his own convenience and pays for that convenience himself and the cell phones have the same local area codes so the caller does not know he is calling a cell phone.
I like the European system better.
