1-Week Trip, quick answers
Does the 7-day validity actually cover a week?
Yes — it activates when you land, so any extra days are buffer for a delayed flight home, not a shortfall you're paying to avoid.
What if I run low on data with days left?
Buy a top-up plan any time from travelren.com — a new QR code lands by email in minutes, no need to remove the first eSIM.
Does this work everywhere in China, or just the main cities?
Nationwide — the same eSIM runs on China Unicom and China Mobile across the country, not just a single city network.
