1900MHz and 850MHz and / or Quad band phones
[QUOTE=Gato Hunter]You need to bring GSM phones. In the US that's T mobile and ATT. Verizon is CDMA. I don't believe there are any CDMA carriers in Argentina.[/QUOTE]In addition, you will want to make sure that the GSM phones work within the frequency bands that are used in Argentina, which are 850MHz and 1900MHz. A quad band phone (also works on 900MHz and 1800MHz, usually) will be your best bet to insure interoperability with one of the carriers in Bs As. If the phone is unlocked, you should be able to pop in a local sim card and have service.
If you have not unlocked the phone, make sure to do so in the country where you got it so that the phone can communicate with the network (to which it is locked) during the unlocking process.
I have used many different phones in Bs As, the only one that would not work is a tri-band phone that does not work on 850MHz.
If you have an extra "cool" unlocked phone (the more current and hip the better) that will work in Bs As, you may want to consider giving it to your favorita, since gadgets like that are pretty pricey in Bs As.
AT & T allowing Skype iPhone calls over cell network
Bit of a surprise.

Good Experience at Personal Today
I made my annual pilgrimage to the Personal office on Callao today to get my cellphone working here and the experience was better than usual. First of all there was practically no line. I don't know if that was luck or if they have improved their process. Then I was concerned about not having my passport with me. But when they understood that I had used their service last year they were able to find my passport number in their system and that was good enough.
Then I had a short wait for the guy who does the real work and he spoke passable English. My chip from last year no longer was valid so he gave me, no charge, a new chip - and made it be the same number as I had last year. He told me the number would be in service within 24 hours. Based on past experience that is optimistic. I wanted to buy time but he said that I could not buy time until the number was in service. That hasn't been the case in the past but in the past I was buying a new number. Maybe it is different when a previously used number is being rehabilitated.
