Your WorldESIM will provide robust signal coverage while docked at the ports in Buenos Aires and Montevideo or Colonia del Sacramento. However, as the Buquebus ferry crosses the vast Río de la Plata, it's typical for the internet connection to become intermittent or drop entirely in the middle of the journey. Connectivity should resume as you approach the destination coast.
