Your eSIM On Trip will provide strong signal at the ports in Dar es Salaam and Zanzibar. However, during the open ocean crossing on the Azam Marine ferries, expect the connection to drop to 3G or even be lost briefly. It's a great time to enjoy the views! You'll reconnect as you approach your destination island.
