Can I use my blocked T-Mobile IPhone 5S in another country?

I have a blocked IPhone 5S that is blocked from T-Mobile.

Could this phone work abroad? In other words, If I take this phone to Colombia, could it work?

I have heard that this devices are global.

A blocked phone has a blacklisted IMEI. It won;t work, and it doesn't matter where you take it.

Nope, once Blacklisted, that GSM phone is NOT going to be able to be activated on any GSM carrier in North America (including Canada and Mexico) or Europe.

The IMEI blacklisting is ALSO global. It might be possible in South America, but if that is a risk you are willing to take, go for it.
