First of all: I got my cellphone and prepaid card (with CTI) without any problems, didn't need a DNI, didn't need my passport... and it works perfectly well to call abroad with it, never had any problems with that.
Secondly: why does every thread here get so ugly, with people being mean to eachother, badmouting other foreigners staying in BA, complaining about Arentina/ argentinians/ prices/ service/ yadayada and accusing others of not "being here for the right reasons"?
Are all expats here that unhappy and frustrated? Or are expats in general just not nice people?
