Lempart Flex is a travel eSIM with unlimited data plans for 214 destinations, for 1 to 30 days. Each plan gives a daily amount of full-speed data; after that the data stays unlimited at the speed you picked. A slower plan costs much less; pay for full speed only when you need it.
Basic — Everyday browsing, messaging, maps and booking rides — the lowest price.
EverydaySuggested — Our suggested plan: more room for social media and video.
Extra speed — A faster connection after the daily amount, for heavier video and hotspot.
Other daily amounts are on each destination's page.
An unexpected phone update or a photo backup should not use up the data you need to find your hotel. Reaching the daily full-speed amount changes the speed, not the amount of data left.
Lower prices on some destinations
On Japan, China, South Korea and Thailand our 7-day unlimited eSIM plans cost a fraction of what the best-known travel eSIM apps charge for theirs (checked October 2026; their plans include more full-speed data a day).
