Hi everyone, where can I get a prepaid cell phone SIM card? I asked at a little mini market type store here in Puerto Madero and they said I could get a "chip" to load up with 30,40,50 pesos of calls at any "kiosk". So being just off the bus - where would I find these "kiosks" is there where they would sell magazines, cigarettes etc.? Do you need any ID to buy a "chip". In Bangkok for instance when you got assigned a phone number you had to show your passport. Thanks!
