Manet Travel does not provide an unlimited data eSIM plan for Tonga. The most generous fixed‑data offering is a 50GB bundle that is valid for 30 days, and lower‑volume options of 20GB, 10GB, 5GB and 3GB on the same 30‑day validity.
Travelers who need more data can choose one of these fixed‑data plans, such as the 20GB/30‑day option, which may be more cost‑effective than a pay‑as‑you‑go alternative unless the user is an extremely heavy data consumer.
