Best travel eSIM China: 12 plans that beat $18/day roaming
Updated October 16, 2026 · Cellulo Team
Land in China without a plan and your Canadian carrier starts billing $18/day. Stay a week and that is $126 for one phone, or $252 for two people, before you have even posted a photo, opened Google Maps, or called a ride.
The best travel eSIM China option is usually a Cellulo data-only eSIM installed before you leave. For the same 7-day trip, you can pay $6 for 1GB if you are careful with data, or $39 for unlimited data if you want to use maps, messaging, video calls, and uploads without watching every megabyte.
Why a China eSIM makes more sense than roaming
China is not the place to land and hope airport Wi-Fi will carry you through. You need data the moment the plane touches down: immigration emails, hotel confirmations, maps from the airport, ride-hailing apps, translation tools, and messaging family back home. If you are travelling for work, add email, Slack, and video calls. If you are creating content, you need enough data to upload stories and clips throughout the trip, not just when you get back to the hotel.
Carrier roaming turns all of that into a meter running in the background. At $18/day, a 10-day trip costs $180. A 15-day trip costs $270. Compare that with Cellulo's China eSIM plans: $50 for 10 days of unlimited data or $70 for 15 days of unlimited data. Even the heaviest user comes out ahead.
All China plans on Cellulo are data-only eSIMs, so they do not include local calls or SMS. For most travellers, that is fine. WhatsApp, FaceTime, Google Meet, and other internet-based apps handle the communication side. The bigger priority is reliable mobile data on arrival.

| Unlimited data | 15 days | $70 | Get Plan | Heavy two-week user |
| 3 GB | 30 days | $15 | Get Plan | Long stay with light usage |
| 5 GB | 30 days | $23 | Get Plan | Remote worker on Wi-Fi |
| 10 GB | 30 days | $38 | Get Plan | Balanced month-long stay |
| 20 GB | 30 days | $57 | Get Plan | Business traveller |
| Unlimited data | 30 days | $98 | Get Plan | Digital nomad |
The 7-day unlimited plan at $39 is the strongest middle ground for most travellers. It costs less than three days of carrier roaming, activates automatically when you arrive in China, and gives you room to navigate, translate, message, and upload without rationing data.
Which China eSIM plan is right for your trip
If you are only in China for a few days, the 3-day or 5-day unlimited plans are the cleanest options. They suit quick trips where convenience matters more than squeezing every dollar.
If you are staying a week, the choice comes down to how you use your phone. The 1GB plan at $6 is cheap enough to justify even as a backup connection, but it is not for heavy maps use, hotspotting, or regular video calls. The 7-day unlimited plan is the safer pick for most people.
For two weeks or longer, the split between light and heavy usage matters more. A traveller mostly on hotel or office Wi-Fi can get by on 2GB over 15 days or 3GB to 5GB over 30 days. Anyone relying on mobile data throughout the day should look at 10GB, 20GB, or unlimited.
A quick comparison makes the savings obvious. A 15-day China trip on Bell, Rogers, or Telus roaming costs $270. Cellulo's 15-day unlimited eSIM costs $70. For a couple travelling together, that is $540 in roaming versus $140 for two eSIMs.
How to set up your China eSIM properly
Install the eSIM before you leave Canada. You need Wi-Fi for installation, and doing it at home is easier than trying to sort it out after landing.
Once installed, leave it ready on your phone and let it activate automatically on arrival in China. Before you land, turn your Canadian line off completely in your phone's cellular settings. Do not just switch off data roaming. If the Canadian line stays active, it can still trigger roaming charges.
Do not use Airplane Mode as a workaround. Airplane Mode disables the eSIM too. The right move is to turn off the Canadian line specifically and use the China eSIM for data.
If you need a one-time password or 2FA text on your Canadian number, briefly turn that line back on, receive the code, then switch it off again.
What to expect from a China travel eSIM
A China eSIM gives you mobile data through local networks in China. That is what matters for getting around, booking rides, checking reservations, using translation apps, and staying connected across the trip. Coverage can vary outside major cities and rural travel routes, so travellers heading well beyond urban areas should plan with that in mind.
For most Canadians, the expensive part of a China trip is not the flight or the hotel add-on. It is the silent $18/day roaming charge that keeps stacking up unless you replace it with a cheaper data plan before you go. Cellulo's China eSIM plans let you pick the right amount of data for your trip and get connected as soon as you land.
