Will I have internet access on the Buquebus ferry crossing to Uruguay?

You will experience strong cellular signal and high-speed data connectivity while the Buquebus ferry is docked at the ports in both Buenos Aires and Montevideo. However, during the open-water transit across the expansive Rio de la Plata, expect a significant degradation or complete loss of cellular signal. Connectivity typically resumes as the ferry approaches the destination coastline and re-enters the range of land-based towers.
