Which countries are in this China + Japan + Korea regional pack?

This pack lists 3 countries. If the plan allows a top-up, extra GB stays on that list. A country that is not listed needs a new QR.

Do I need a VPN in mainland China?

Hotel Wi-Fi and a local Chinese SIM are filtered: Google, WhatsApp, and Instagram often fail. Airalo’s China help (2026) says their China, Asia, and Global packs are roaming-routed, so a VPN is not required. We do not promise that bypass on this QR. If Maps or WhatsApp fail on this line, use a VPN you already installed at home. Do not wait to download one in China.

Can I top up the China + Japan + Korea regional plan?

Same profile, same coverage. Extra GB is a top-up, not a new QR.
