GigSky does not provide an unlimited data eSIM for North America. All of its North America‑specific plans have a fixed data cap, such as 50GB for 60 days, 20GB for 180 days, or 100GB for 180 days, all delivered over 5G networks.
If a traveler needs a large amount of data, a fixed data plan can be more cost‑effective than a pay‑as‑you‑go option, unless the user is an extremely heavy data consumer who would benefit from an unlimited plan.
