Lumbus does not provide a true unlimited data eSIM for the United States of America. Its plans for that country are fixed data bundles. The largest offerings give 50 GB for 30 days or 180 days, while a 20 GB bundle is available for 30 days or 90 days.
Plans titled “United States Unlimited” or “North America 3 Unlimited” actually grant a daily high‑speed allowance of 3 GB and then lower the speed to 1000 kbps after that limit is reached. Travelers who need extended data can choose a larger fixed bundle, which can be more cost‑effective unless the user works far beyond the daily allowance.
