What the table does not show
Airalo’s unlimited plans drop to 1 Mbps after 3 GB per day; Saily’s plan data lists 5 GB per day at full speed first. That difference matters more for video calls than for maps and messages.
Airalo has fixed plans for 3, 7 and 15 days as well as 30, which fits a short trip. Saily’s fixed plans are for 30 days, with one 7-day 1 GB plan. Prices have separate check dates: see the date column on each provider’s own page.
How to pick
- Fixed data, short stay: compare the fixed rows first. They are the clearest to read.
- Unlimited: read the speed rule before the price. The two providers do not throttle the same way.
- Phone and travel plan: check eSIM support and carrier unlock on your exact model before you buy either one.
Questions before you go
Is Airalo or Saily better for China?
Neither wins everywhere. Airalo is cheaper on 7 of the 8 plans both sell. Compare the speed rules on unlimited plans and check which one starts validity when it suits you.
Can I use two eSIMs on one trip?
Many phones can hold more than one eSIM, but only one line handles mobile data at a time. Check your model before you rely on a backup.
