Yes, having data from EastESIM is highly recommended for hiking in Asian national parks, even if you plan to download offline maps. While signal might vary in deep valleys or dense forests, you'll typically have strong coverage at park entrances, visitor centers, and popular viewpoints. This is crucial for checking weather updates, communicating in emergencies, or downloading up-to-date trail information before you start your trek in places like Doi Inthanon National Park in Thailand or Kinabalu Park in Malaysia.
