What is the DataESIM internet signal like at the RMS Rhone shipwreck site in the BVI?

DataESIM generally provides a functional signal on the boat deck near Salt Island, allowing you to finalize dive preparations or share pre-dive updates before descending to the RMS Rhone. However, once you submerge for the dive, cellular signal will be lost entirely. DataESIM's service is designed for surface-level connectivity; underwater environments are beyond the scope of typical cellular network penetration. Plan to be offline during the actual dive.
