Im in sp now and can anybody tell me where I can buy a prepaid phone card to call back home?

Its like those 5$ cards that lasts for hours but depends on where ur calling..

Yes, there are plenty of calling cards you can buy. I was there not long ago and I needed to make a call from the bus terminal and sure enough I bought a few to have and used them all. I can remember the companies but you can get at the newspaper/magazine stands or even in pharmacies. You will find if you ask, there people help. Just know who to ask. In a good store, or pharmacy they might know. Just try. http://recarga.com.br/ (Just so you know check this website) Prepaid cards, and you can recharge. (EMBRATEL is the company and the word is: cartao telefonico)

Right, those people think their phone card is like our prepaid cards, but it's totally different. Their cards are made to swipe on paid phones or charge prepaid cell phones. They don't know how American prepaid phone cards work. Report It

You can find prepaid card in almost everyplace, Malls, Libraries, Lotteries, etc... If can look for help too, Brazilians are very pleasant...

I highly recommend PhoneBell http://www.phonebell.net

No such thing in Brazil, the prepaid cards over there are to be used only on public phones because they don't use change like here, instead of coins you have to slide a card to make calls.
Some phone companies have lower rates on nigh time, you can check the operators over there.
Some people use the internet to make online calls to the US. Anyway, even the regular international rates are not so high in Brazil, way cheaper than making an international call from the US.

Different from USA e Europe we dont have a really good calling cards.... My suggestion is SKYPE, try it at your hotel or any lan house. There is a big one at ANA ROSA underground station (Rua Vergueiro 2040) called ROX, they have a very nice VIP area with web and microphone. It will save u lots of money

Calling from Spain to USA, the best rate is 1.9 cents / min with maintenance fee, or 3.4 cents / min without maintenance fee. the above currency is USD.
