Why an eSIM is Essential for Tonga
No Free EU Roaming
Unlike European countries, Tonga does not benefit from free EU roaming. Your home plan will be expensive: between $2 and $5 per MB depending on your carrier. For a one-week trip with moderate usage (browsing, social media), you can easily spend $50 to $100 on roaming.
Limited Free WiFi
Free WiFi is limited in Tongan hotels and resorts, especially on outer islands:
- Availability: limited outside Nuku'alofa and main tourist areas
- Security: unsecured public networks, hacking risks
- Reliability: unstable connections, frequent dropouts
- Mobility: impossible to use while traveling (island hopping, diving, remote beaches)
An eSIM offers secure and reliable connectivity everywhere, essential for traveling in Tonga, especially for island hopping.
