Airalo eSIM Data Plans for Tonga

Airalo does not provide a truly unlimited data eSIM for Tonga. The plans that include “Unlimited” in their name give a cap of 3GB per day; once that limit is reached the speed is throttled to 1000 kbps. For travelers who need more data, fixed‑data plans are available. For example, Oceanlink offers a 50 GB plan that is valid for 30 days and costs $99 USD, and a 20 GB plan valid for 15 days for $47 USD. These fixed‑data options can be more cost effective unless a user requires very high data usage.

Airalo does not offer any eSIM plans for Tonga that include a phone number or SMS capability. All available options are data‑only, providing internet access but no inbound or outbound voice or text services. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

Airalo provides 14 single‑country data plans and 19 multi‑country plans that include Tonga. The pricing for these plans ranges from about $4.50 to $99.00, while the data caps span from 1 GB to 50 GB. Within the catalogue, 9 plans feature a daily data‑cap structure—meaning the allotted data is reset every 24 hours—whereas 24 plans offer a fixed data amount that is used over the entire validity period. A small subset of plans may include a reduced‑speed option that caps throughput at 1 Mbps.
