In a word: yes.
I’ve lived in the Dominican Republic for about a year total and there are plenty of places in that Carribean nation that will never be sufficient for stuff like video conferences. Many places in latin america just don’t have strong fiber connections, or any fiber at all (even when they do the “last mile” problem with network connections makes it extremely shoddy despite having fiber to your home).
Where I am (the El Tabor area in the north of Barranquilla) the internet through Claro is more than fast enough. So far, I have had to miss only one (1) meeting because the power went out for about two hours. I had a hotspot through my cell phone working and informed my boss in advance, who quite nicely said I could skip it. But you get my drift. If the internet in Barranquilla has proved sufficient over 4 months of 3-4 zoom meetings per week: it will suffice.
It is not quite as fast as I would like, but it does the job. Try that in most places in Puerto Plata, or Santo Domingo DR: forget it. (Santiago, DR, however, is often really good for internet FYI.)
