Hong Kong & China Unlimited data
12-day plan

No speed cap (tethering capped at 500MB/day)

This plan requires real-name registration (identity check) by the network operator. It applies wherever you use it. [The order matters] 1. Scan the QR code first and install the eSIM on your phone 2. Then register your passport details yourself on the carrier's page (https://global.cmlink.com/store/realname?LT=en) Registration will not go through before the eSIM is installed. The eSIM cannot be activated until registration is done. [Register once only] Once you see the confirmation, your registration has been accepted. **Do not submit the same details again** — a duplicate submission stalls the process. We never hold your passport details. If you would rather not register, we refund in full, since the eSIM will not have been activated.
Tethering (hotspot) is limited to 500MB per day
The date rolls over around 01:00 Japan time — activating just before that can burn most of day one

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.

How activation works

Starts when the eSIM first connects to a local network at your destination — installing it before you leave does not start the clock.
