iRoamly does not provide an unlimited data eSIM for Tonga. All of the plans listed for Tonga have a data cap of 2GB per day, which is a hard limit for each day of validity.
Travelers who need data in Tonga can choose from iRoamly’s fixed data plans, such as the Tonga‑eSIM‑2GB‑1 Day‑Daily, Tonga‑eSIM‑2GB‑3 Days‑Daily, or Tonga‑eSIM‑2GB‑5 Days‑Daily. These plans give 2GB of high‑speed data each day for 1, 3, or 5 days, respectively, and can be more cost‑effective for most users unless very heavy data consumption is expected.
