What the table does not show
Yesim’s page lists fixed plans of 1 to 30 GB, all valid for 30 days, and a daily rate for unlimited use. Saily’s plan data shows fixed plans of 3 to 20 GB for 30 days and unlimited plans from 5 days, with 5 GB per day at full speed before the 1 Mbps limit.
Saily’s prices on this page were checked on Oct 5, 2026, earlier than Yesim’s. Look at the date column before you compare.
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 Yesim or Saily better for China?
Neither wins everywhere. Yesim is cheaper on 5 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.
