Hong Kong & China 50GB total (China Unicom)
180-day plan

This is a data-only plan — no phone calls, and no sending or receiving SMS.
On Android, the TikTok app cannot be used on this network (it works on iPhone). Google, X, Facebook, YouTube and LINE all work as usual, with no VPN. This can change at the network operator's discretion. (From the network operator's sheet dated 2026-09-14. TikTok may work on some devices, but we cannot guarantee it.)
The date rolls over around 01:00 Japan time — activating just before that can burn most of day one

Only with eSIM.co.jp

Support you can count on
If a network problem stops you using the plan, we look into what happened and then refund you or send a replacement eSIM.
Keep your Japanese number
Your Japanese line stays in the phone. Your number and LINE do not change.
Support on LINE
Stuck on setup? Message a real person on LINE. Just add us as a friend — no phone call, no account.
