Wireless Internet Card

Which area are you looking at?
Besides Verizon, Sprint/Nextel & Cingular their may be a regional provider that you can use.

 

These ones I mentioned are US providers, and can go international, but not for an extended time since the roaming fees would be too high.

Maybe someone else can post a provider that will work for you in Brazil & not cost you a fortune.

If you are living in Brazil and plan to use your service in Brazil, you are better off using a Brazilian carrier. Here's a list of carriers in Brazil:

As for the US carriers listed in the previous post above, you will need to enter a ZIP code to view their plans and coverage. You can enter the zip code 10026 which belongs to New York City. After you enter the zip code, you'll see the plans they offer and their cost.

 

Sierra Wireless makes good data cards, which are often re-branded by operators:
