Travel Technology - Sao Paulo Prepaid SIM

I will be going to Sao Paulo, Brazil mid-July this summer and am looking for a prepaid SIM to use while there. I've seen a few on the net but those seem to be geared towards users in Rio de Janeiro. Ideally I'd like one that would get me a local number in Sao Paulo and the ability to call back to the US at a reasonable rate. My hunch is that there are some to be had once I arrive in Brazil but it would be nice to get one in advance.

I've bought UK and all-country SIMs from Telestial (http://www.telestial.com) in the past and the service has been good. I would buy from them again (haven't checked on their availability for Brazil though).

Thanks for that info. It looks reasonable (rates/roaming/number). I might go with that one if I can't find one that has a local Sao Paulo number.

As far as I know you can get a SIM card at any mall. All Shopping Centres will have Telecom Reps that will gladly sell you a SIM card for your phone... Look for TIM and CLARO - these are the Telecom Operators for Sao Paulo you might be interested...

I have bought prepaid SIMs in many countries around the world, but when I tried to do this in Sao Paulo, they asked me for some sort of national identity card and other info that I didn't have. I had to drag a local with me to the mall to supply his info before I was successful in getting one.

The only reason I mention this is that if you plan to get a prepaid SIM in Brazil, I recommend doing it at the airport, where they are certainly accustomed to dealing with arriving foreigners, versus at the local mall, where they might not know how to handle that.

One more similar question. Are there sim's that have prepaid GPRS available? It's probably stretching my luck trying to find this but it might be worth a shot. Thanks!

It's true that they will ask you to provide some documentation. This was implemented a while back as a means to prevent fraud and crime. Many criminals were using these disposable SIM chips that were 100% untraceable.

I don't know what a foreign national could provide in terms of identity. I'll find out and try to post back.
