Unlimited eSIMs: how the daily limit works
Updated 12 November 2026
Most unlimited travel eSIMs give a fixed amount of fast data every day, often 1 to 3 GB, then slow the connection, to something like 512 kbps or 1 Mbps, until the day resets. Data never stops, but the speed does.
What still works after the limit
- Fine: messages, email, maps, music at low quality, browsing simple pages.
- Slow: photos on social media, voice calls over apps at 512 kbps.
- Hard: video calls, HD video, large downloads, sharing your connection with a laptop.
When unlimited is worth it
If you use more than about 1.5 to 2 GB a day, every day, unlimited usually costs less than a big fixed plan. Below that, a fixed amount of data is cheaper.
For a week in Japan with heavy use, the cheapest unlimited plan is $19.29 with Wigoo, 2 GB a day at full speed, and the cheapest plan with enough fixed data is $12.49 with Wigoo, 20 GB, valid 30 days (read 12 November 2026).
How findbestesim ranks unlimited plans
An unlimited plan only counts for your trip if its daily fast data covers your daily use: 1 GB a day at full speed does not count for "about 2 GB a day". The rule is on How we rank.
When the day resets depends on the provider: some at midnight in a fixed time zone, some 24 hours after you start. Check the plan's page.
Questions
Is an unlimited eSIM really unlimited?
You never run out of data, but after the daily amount of fast data the speed drops until the next day.
How fast is the connection after the daily limit?
It depends on the plan, often 512 kbps or 1 Mbps: enough for messages and maps, not for video.
Is unlimited better than a fixed plan?
For heavy daily use, often yes. For maps and messages, a fixed plan costs less.
