This Polynesian kingdom in the South Pacific consists of more than 170 beautiful islands, with bright white beaches and coral reefs.

A Tonga eSIM connects your device to a local network, giving you affordable prepaid mobile data.

How much travel data do I need with my Tonga eSIM?
Your data requirements in Tonga largely depend on your travel plans and personal usage. If you plan on enjoying the tropical outdoors and exploring the pristine beaches, you can’t rely on Wi-Fi availability.
The best thing about a Tonga eSIM is that it comes with flexible data plans, so you can start with a smaller package and top up as needed.
We also have a travel data calculator to help you estimate how much data you’ll need for your trip.

Will I pay roaming charges with a prepaid eSIM for Tonga?
Not at all. A Tonga eSIM is an affordable option that helps you save on roaming charges. With a Tonga eSIM, you won’t pay any roaming charges because it connects you directly to a local network.
To avoid roaming charges on your primary SIM, please make sure you’ve turned off Data Roaming on your primary SIM (and confirmed you aren’t enrolled in a carrier travel plan) to prevent your home carrier from adding roaming charges to your next bill.
