What is the DataESIM internet signal on the Dar es Salaam-Zanzibar ferry?

DataESIM users can expect robust 4G LTE signal coverage at the ports of Dar es Salaam and Zanzibar. However, during the open ocean transit segment of the Azam Marine ferry crossing, the cellular signal will likely degrade to 3G or experience intermittent loss. While we strive for maximum coverage, maintaining consistent high-speed data across vast stretches of open water presents inherent challenges.
