Best travel eSIM China: 12 Cellulo plans that beat $18/day roaming
Updated September 6, 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 checked maps, called a ride, or opened your hotel confirmation.
The best travel eSIM China option is usually the one that covers your full trip without pushing you into carrier roaming. On Cellulo, China eSIM plans start at $6 CAD for 1GB over 7 days, while a 10-day unlimited plan costs $49 CAD. Even the biggest 30-day unlimited option at $96 undercuts six days of roaming.
All of these are data-only eSIMs, so they do not include local calls or SMS. For most travellers, that is fine. You need data for maps, rideshare, messaging apps, email, translation, and travel bookings. That is what actually matters when you land.
Best travel eSIM China plans compared
If you want to stay connected in China without paying roaming charges, here are the current Cellulo options.
| Data | Duration | Price (CAD) | Get Plan | Best For |
|---|---|---|---|---|
| Unlimited data | 3 days | $16 | Get Plan | Weekend city break |
| Unlimited data | 5 days | $27 | Get Plan | Short business trip |
| 1 GB | 7 days | $6 | Get Plan | Budget backup data |
| Unlimited data | 7 days | $38 | Get Plan | ⭐ Most Popular — Week-long trip |
| Unlimited data | 10 days | $49 | Get Plan | Multi-city holiday |
| 2 GB | 15 days | $11 | Get Plan | Light traveller |
| Unlimited data | 15 days | $68 | Get Plan | Two-week heavy use |
| 3 GB | 30 days | $15 | Get Plan | Long stay with Wi-Fi |
| 5 GB | 30 days | $22 | Get Plan | Casual explorer |
| 10 GB | 30 days | $37 | Get Plan | Remote worker lite |
| 20 GB | 30 days | $56 | Get Plan | Business traveller |
| Unlimited data | 30 days | $96 | Get Plan | Digital nomad |
The standout for most people is the 7-day unlimited plan at $38 CAD. A typical one-week trip to Shanghai, Beijing, or Guangzhou can burn through data fast once you are using navigation, translation, messaging, and uploads every day. At $38, it is still far below the $126 your carrier would charge for the same week.
China roaming cost vs Cellulo eSIM
The math gets ugly fast with Canadian roaming. Rogers, Bell, and Telus charge $18/day in China. That means:
- 3 days: $54 in roaming vs $16 for Cellulo unlimited
- 7 days: $126 in roaming vs $38 for Cellulo unlimited or $6 for 1GB
- 10 days: $180 in roaming vs $49 for Cellulo unlimited
- 15 days: $270 in roaming vs $68 for Cellulo unlimited
- 30 days: $540 in roaming vs $96 for Cellulo unlimited
For a couple travelling together, a 10-day trip can mean $360 in roaming charges. Two 10-day unlimited China eSIMs on Cellulo cost $98 total. That gap is why so many Canadians now buy an eSIM before they leave.
The convenience matters too. Your plan activates automatically on arrival in China, so you can get online as soon as the plane lands. That means maps work on the way out of the airport, your hotel booking is still in your inbox, and you can order a ride without hunting for airport Wi-Fi or a SIM counter. If you are travelling for work, it also means email, Slack, and video calls are available right away instead of waiting until you reach the hotel.
How to use an eSIM in China without triggering roaming
Install the eSIM before you leave Canada. You need Wi-Fi for installation, so do it at home or somewhere reliable before travel day.
The important part is what happens before landing. Turn your Canadian line off completely in your phone's cellular settings. Do not just disable data roaming. If your Canadian line stays active, your carrier can still register you on a partner network in China and trigger the $18/day roaming charge.
Use the China eSIM for all data once you arrive. If you need a one-time passcode or 2FA text on your Canadian number, turn that line on briefly, receive the code, then turn it off again.
Do not use Airplane Mode as a workaround. Airplane Mode disables the eSIM too. Turn off the Canadian line specifically and leave the travel eSIM active.
Which China eSIM plan makes sense for your trip
A short trip usually calls for unlimited data. China trips tend to be navigation-heavy, especially if you are moving between airports, train stations, hotels, and meetings. Translation apps, messaging, and live map use can chew through a small bucket faster than people expect.
For 1 to 5 days, the 3-day or 5-day unlimited plans are the cleanest choice. For a standard vacation, the 7-day unlimited plan is the safest pick. For 10 to 15 days, unlimited still makes sense if you expect to work, upload photos, or rely on data all day.
The capped 30-day plans are better for travellers who know they will spend a lot of time on trusted Wi-Fi and mainly need mobile data for directions, messages, and occasional browsing. The 30-day 10GB plan at $37 CAD is a sensible middle ground for a longer stay. If you are creating content, tethering occasionally, or working remotely, the 20GB or 30-day unlimited plans are the safer bet.
What to expect from a China eSIM
Cellulo's China plans connect to local networks in China. Coverage is generally strongest in major cities and travel corridors. If your trip includes remote rural areas, expect coverage to be less predictable than in Beijing, Shanghai, Shenzhen, or other large urban centres.
Because these are data-only plans, you will want to use apps like WhatsApp, FaceTime, or other internet-based services for calls and messages. That is enough for most travellers and usually better than paying your Canadian carrier to roam.
