Avelis eSIM does not provide an unlimited data eSIM for Tonga. All available plans for Tonga have a specific data cap, ranging from 3GB to 20GB, and each plan has a defined validity period. Travelers who need a larger, uninterrupted data allowance can choose from the fixed data plans such as the Standard 20GB / 30 Days or the Standard 10GB / 30 Days. These fixed data plans are typically more cost‑effective for most users unless very heavy data consumption is expected, in which case a pay‑as‑you‑go option could also be considered.
