A wireless plan costs $100 USD, how to they afford that? Americans get ripped off!!!!
Well,, there are some cheaper plans available even in the US.
Just googling, T-mobile offers starting package for like $10 a month (probably many strings attached?). US costumers prefer better, more expensive plans, but people in poor countries are stuck with the cheapest plans.
Ditto with almost all stuff. They get the cheapest, poorest quality or second hand stuff.
E.G. Hispanics make great car technicians. They are trained to fix any car, in any condition, using no parts.
Cuba still has many US made cars from 1950ties daily on the road. Without access to parts!
They are just creative.
