Simfinity eSIM Data Plans for Tonga

Simfinity does not provide an unlimited data eSIM for Tonga. All of its plans for the country have a fixed data cap, ranging from 5GB up to 25GB on a “Pacific Islands Pass” which combines coverage across Tonga and two neighboring island states.

Travelers who do not need a high‑volume plan may choose a fixed‑data option such as the Tonga 20GB plan valid for 30 days and priced at $203.00 USD, or the Tonga 10GB plan for 30 days at $108.00 USD. These alternatives can be more cost‑effective for moderate data usage compared to plans with larger caps.

Simfinity does not provide eSIM plans with a phone number or SMS capability for travelers in Tonga. All of the available Tonga eSIM options from Simfinity are data‑only, meaning they offer high‑speed internet without inbound or outbound voice or text services.

If you need to make calls or send messages while on the island, you can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. These services allow communication without a local phone number or SMS support.

Simfinity offers a total of eleven distinct data plans for Tonga, split between single‑country and multi‑country options. Seven plans cover only Tonga, while four plans include Tonga plus other destinations. The available plans provide data caps ranging from 1 GB to 25 GB and are priced between $14.80 and $203.00 USD, with a standard 30‑day validity. Some of the plans allow tethering, giving customers flexibility to share the connection with other devices.
