Answer
Yes, Starlink can be purchased and set up for home internet in Uruguay. It is worth considering as a separate connectivity option, especially if a regular connection at the address does not provide the necessary stability.
However, having this option does not remove the usual practical considerations. You need to understand where the equipment will be installed, whether there is a suitable location with an unobstructed view, who is responsible for installation, and how it complies with the building's or rental property's rules.
For remote work, Starlink can form part of a backup setup rather than be the only connection you rely on. It makes sense to compare it with the available home internet connection and mobile internet: reliability, cost, ease of maintenance, and performance in bad weather are important.
