Will I have internet coverage at the Cu Chi Tunnels historical site in Vietnam?

You will generally have strong EastESIM signal at the entrance, visitor center, and above-ground areas of the Cu Chi Tunnels. This allows you to share photos, research historical context, or coordinate with your group. However, as you descend into the actual underground tunnels for exploration, connectivity will naturally be lost. It's a unique opportunity to experience history firsthand without digital distractions, but you'll reconnect once you emerge back into the open air near Ho Chi Minh City.
