Hello, I lived in the US for 4 years, but due to financial problems I had to go back to my home country (Brazil). I have an iPhone 6s I bought on Verizon in their monthly instalments plan, and so far I've been paying the instalments regularly; the phone works fine with a Brazilian SIM card. Unfortunately, my dad had a stroke a month ago and lost his job, and my family doesn't have enough money to pay the remaining balance ($500). So, what happens now? Could Verizon somehow block my phone remotely, making it useless? Will I still be able to use it in Brazil? Thanks in advance.
