Lumbus does not provide a genuine unlimited data eSIM for North America. The only plan marketed as “Unlimited” offers a fixed daily limit of 3GB, with speed reduced to 1 Mbps after that allowance is reached; the Data cap column lists a hard limit and the plan expires after the chosen number of days. No plan in the catalogue has a data cap denoted as unlimited.
Travelers can instead choose Lumbus fixed‑data plans, such as the 20GB plan valid for 30 days or the 50GB plan valid for 180 days, both of which supply a set amount of high‑speed data and end after the validity period. These alternatives may be more cost‑effective for most users, unless a traveller expects to consume data far beyond the fixed allowances.
