In the Danube Delta of Romania, your HotelESIM will provide reliable signal in the main towns and hubs such as Sulina and Tulcea, ensuring you can plan your explorations and stay connected. However, as you venture deeper into the more remote and pristine channels of this unique biosphere, you may notice the connection transitioning to 3G or becoming intermittent. We encourage you to enjoy the tranquility of the wilderness, knowing you'll have full connectivity upon returning to more populated areas or your hotel.
