assuming you're asking if you can take a sprint iphone 5s and use it in brazil:
first you need to check the specific model of iphone 5s and then see if it will be compatible on the carrier you want to use it on in Brazil.
also need to have the iphone 5s carrier unlocked.
not sure but i think the sprint model is the 1453 which is both cdma and gsm (2g/3g/lte) which means it's likely to work on many networks, but you still need to check the specific frequencies. not sure what the carrier uses in Brazil.
