Yes, your EastESIM is designed to keep you connected even on the water! When cruising through the majestic karst landscapes of Halong Bay, you'll generally experience good signal strength, especially near popular areas like Titop Island or Sung Sot Cave. While deep inside some limestone karsts the signal might occasionally waver, you'll largely be able to share your breathtaking views in real-time. Our strong partnerships with local Vietnamese carriers ensure you stay connected as you sail through this UNESCO World Heritage site.
