While cruising the magnificent Ha Long Bay in Vietnam, EastESIM generally provides good internet coverage, especially around the more populated areas and near larger islands. You'll typically have signal to share stunning photos of the limestone karsts or stay in touch with loved ones from your cruise boat. However, as you venture into more secluded coves or between very remote islands, the signal might become intermittent. Our local carrier partnerships aim to maximize connectivity even in this unique maritime environment, but some natural dead zones can occur.
