Can a blocked iphone 5s be used outside of US?

Two months ago I purchased an iphone 5s from craigslist. It was brand new, in a tmobile box. Now two months later, I lost service in my phone and it turns out that the person whom I got it from scammed me. I contacted the person, but i got no response. My only option is to switch my phone with someone I know who is moving to a different country… But I want to know if my phone will work in a different country if its blocked by tmobile in the US?
(I believe The phone was unlocked)

I practically destroyed my IPhone 6?

I cracked my screen a while back, and well a piece of the screen had chipped off, and today, I dropped it, and I had to quickly grab it, and well I guess I grabbed the part that was chipped off, and I pressed down too hard, and well the screen got messed up. There's a pitch black spot about the size of my thumb print and there's nothing but rainbow lines going down, covering about half of the screen. At first I could still use it for a bit, not it's unusable. I can't do anything at all to it. How much is it to repair?

Added (1). If it can't be repaired, what are decent, cheap, touchscreen phones? I don't mind having to temporarily use one of those if my phone can't be repaired.
