Who should choose which
Choose Saily if one esim profile that works across destinations is the thing you care about most and you are happy to manage everything through their app.
Choose eSIM BFF if you travel more than once a year and want one eSIM you never reinstall, the ability to top up when you are already at zero, and no app. For families, ordering several eSIMs in one checkout and seeing them in one dashboard is the difference that gets mentioned most.

eSIM BFF vs Saily questions
Is eSIM BFF cheaper than Saily?
Similar to Airalo. Extras like the security features are bundled into plan pricing. Our 5 GB Europe plan is HK$45.96 and 5 GB in most of Asia is HK$61.54, tax included. Check Saily’s current price for the same destination — prices change often and we would rather you compare live numbers.
Can I switch from Saily to eSIM BFF mid-trip?
Yes. Install eSIM BFF on Wi-Fi (two minutes), buy a package for the country you are in, and switch your mobile-data line to it. Your Saily eSIM can stay on the phone or be deleted once its plan expires.
Does eSIM BFF have an app like Saily?
No app is required. Installation is a one-tap link or QR code, and the dashboard is a website that works at 0 GB. If you prefer an app, Saily has one; we prefer not making you download anything at the gate.
Do I reinstall an eSIM when I leave Saily behind?
No. eSIM BFF is one profile. Buy a package for the next country in the dashboard and it attaches to the eSIM you already have.
