Tonga's internet, while present, requires an adventurer's mindset. Its infrastructure relies heavily on submarine cables and satellite backups, which means occasional disruptions are part of the journey. In Nuku'alofa and other main towns, you'll generally find 3G/4G speeds adequate for essential communication – think sending messages on WhatsApp, checking weather forecasts, or light browsing. For critical expedition planning, always download maps and guides offline beforehand. Embrace the opportunity to disconnect and immerse yourself in the islands' natural beauty!
