WE are heading over to brazil in another 2 months and I need to be available to get to my email and would like to have option of using a softphone. Most of the time will be spent in the small town of Lins, Sau Palo, but my in-laws do not have a reliable connection that I can use.

Any suggestions on what is the most cost effective way of getting unlimited data and incoming voice in brazil? Can I take some equipment from here that I could use for this?
