History
eSIMs moved from niche to mainstream after handset manufacturers added support around 2018; travel-specific eSIMs emerged soon after to simplify short-term connectivity.
Conservation

Confirm device compatibility
Check that your phone supports eSIM and is carrier unlocked before buying; many China/HK devices lack eSIM support.
Activate with stable Wi‑Fi
Install the eSIM when you have a reliable internet connection (hotel Wi‑Fi or airport lounge) to avoid activation errors.
Preserve the profile
Do not delete the eSIM after installation — it can only be installed once and deletion may forfeit your plan.
Monitor high‑speed usage
This plan uses high-speed allotments then shifts to reduced speeds under FUP; limit video streaming to preserve usable data.

Required to install the QR‑delivered eSIM and access the mobile data plan.
