It is not exactly a coupon system, depending on where you work you might have unlimited Internet access (albeit slow) or you might have a set of traffic quotas for Internet and email, sometimes pretty strict (~20mb per month on aggregated email traffic). However, this is not a centralized system or a government mandate, but more of a necessity for some institutions, for example universities normally have a 512kpbs link (or two if they are really big) and the only way to avoid saturating the link is by assigning these traffic quotas to the users.

All residential Internet access in Cuba is illegal (as in is not legally sanctioned by the government) using good old modems, and only a handful of people in very high government positions can have an officially sanctioned house connection. Everyone else is buying it off the black market.

Cellphone coverage is only basic voice and texting without Internet access, and at horribly expensive rates.
