I have been looking over your previous posts and it looks like you bought an iPhone.
Phones that are bought in the USA are primarily for use in the USA and will not work without a carrier plan first and a roaming subscription. If you attempt to use the phone elsewhere it must be unlocked, but only if it's compatible with the carrier. Also a phone cannot be unlocked unless certain conditions are met. I believe the phone may have to be in service for X amount of months and the account in good standing before unlocking can be requested.

When you buy them unlocked, they are only for use with carriers in the USA from what I've seen on many of the unlocked iPhone pages that Best Buy lists. Unless there is something else I missed and you believe you may be able to use it in your country, I would wait to see if someone else has something they can add to this discussion about this issue.

I'm a little bit concerned that your iPhone 5S you purchased unlocked is not working in the country you're currently in. I'd like to see if I can help somehow.
Would you be able to provide me with the model number of the iPhone 5S you are using? This is generally on the back of the phone or in the settings and begins with an A. It would also help if you can provide me the name of the provider you're using in Brazil so I can investigate this for you.
I look forward to your reply!

I looked up the model number you provided and was able to find these spectrums. As long as your cell provider operates on one of the spectrums below you should be able to use the phone internationally.
Model A1533 (GSM)*: UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 2, 3, 4, 5, 8, 13, 17, 19, 20, 25)
Model A1533 (CDMA)*: CDMA EV-DO Rev. A and Rev. B (800, 1700/2100, 1900, 2100 MHz); UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 2, 3, 4, 5, 8, 13, 17, 19, 20, 25)
