China eSIM for Long Stays: 15- and 30-Day Plans

A month in China is a different data problem from a week. You stop being a tourist — you take video calls, upload photos, use maps every day — and a plan that looked generous for five days looks thin by week three.
Every plan below lasts 15 or 30 days. The question is not which is cheapest, but which combination of allowance and validity fits how you actually use a phone.
For a 30-day stay
Moderate use: 10 GB total, 30 days, $10.01 — about $0.33 a day.
Working remotely: 30 GB total, 30 days, $25.34 — $0.84 per GB.
Daily streaming or heavy tethering: 3 GB/day, 30 days, $50.78 — up to 90 GB at $0.56 per GB, the best rate we sell in China.

How to size a month
- Count your heavy days, not your average — Most long-stay travellers use very little on weekdays and a lot at weekends. A total-data pool absorbs that pattern; a daily plan wastes capacity on quiet days.
- Tethering changes the maths — If you connect a laptop, budget several gigabytes per working day. In that case a 3 GB/day plan is cheaper than buying total-data plans repeatedly.
- Validity is the hard limit — A 30-day plan bought before departure still starts on first connection, so you do not lose days waiting for your flight. But once the 30 days are up, the plan ends even if data remains.
Before you buy
- Install and test the eSIM on Wi-Fi before you leave — a failed install is far easier to fix at home than in a dorm room.
- Keep your home SIM in the phone for bank and app verification codes.
- If you plan to tether, check that your phone allows personal hotspot on a secondary eSIM line.
