eSimfly’s plans that carry the word “Unlimited” for Tonga do not provide an uncapped data supply. Each of those plans offers 3GB of high‑speed data per day and then reduces the speed to 1000 kbps once the daily limit is reached. Therefore, eSimfly does not have a truly unlimited data eSIM for Tonga.
If a traveler prefers a fixed data allowance, eSimfly offers larger bundles such as the Tonga 20 GB 30 days plan or the Tonga 10 GB 30 days plan. These fixed plans give a set amount of data that must be used within the validity period, and they can be more economical for users who need a substantial amount of data without the daily throttling that applies to the “Unlimited” plans.
