When you're out on the boats around Koh Tao, Thailand, preparing for a dive, your EastESIM will provide strong 4G/5G coverage, allowing you to check dive conditions or message your dive buddies. However, as soon as you descend beneath the surface of the Gulf of Thailand to explore vibrant coral reefs and marine life, cellular signals cannot penetrate water. So, while you'll be well-connected on land and at sea level, expect to disconnect digitally while enjoying the underwater wonders of Koh Tao.
