Yes, ASIMGO sells a range of unlimited data eSIM plans that cover Tonga. These plans vary in validity from 1 day up to 30 days and all feature the same network and speed characteristics: they are delivered on 5G, allow tethering, and may be throttled with a maximum speed of 5000 kbps. The plans are explicitly labeled as unlimited and include a fair‑usage policy, meaning that after heavy use speeds may be reduced. If a traveler wants confirmation of the fair‑usage limits or the typical data volume that remains available at normal speed, they should contact ASIMGO directly.
