GigSky eSIM Data Plans for Tonga

GigSky does not provide an unlimited data eSIM plan for Tonga. Travelers who need data in Tonga can choose from fixed‑data options, such as a 100GB plan valid for 180 days, a 50GB plan valid for 180 days, or a 20GB plan valid for 180 days (or 90 days for the 20GB World Plan). These larger data allowances may be more cost‑effective for most users unless an exceptionally heavy data consumer is looking for unlimited usage.

GigSky does not provide an eSIM plan for Tonga that includes a local phone number or SMS capability.
Only data‑only eSIM plans are offered for Tonga, so users cannot receive or send regular SMS or make voice calls using a standard mobile number. However, standard internet‑based messaging and calling apps such as WhatsApp, Telegram, and iMessage can be used over the data connection for communication.

GigSky offers 12 single‑country data plans that cover Tonga alone and includes Tonga in 29 multi‑country plans that span several nearby islands. The price of these plans ranges from free up to about $332.49, while the data amounts go from 100 MB to 100 GB depending on the plan and its validity period. Some of the plans are fixed‑data‑cap, meaning the total data amount is set for the whole validity period, while other plans are daily‑data‑cap, where a daily quota is reset each day.
