Will my CoreESIM provide internet access during the Buquebus ferry journey to Uruguay?

During the Buquebus ferry service across the Río de la Plata to Uruguay, your CoreESIM will typically maintain a strong signal while docked at either port. However, as the vessel proceeds into the open waters of the estuary, the mobile signal from carriers like Antel or Movistar Uruguay often attenuates significantly and may drop entirely mid-crossing. Connectivity usually resumes as you approach the destination coastline.
