Best eSIM for Beijing (2026): Which Network It Roams On, and What Actually Works
You are in Beijing for a week of sightseeing, not for a SIM queue at Daxing. Here is the carrier your eSIM roams on, what it costs per day and per GB, and the one setup step you cannot do after you land.
Quick answer: For a first-time visitor spending five to seven days in Beijing, the Fizen China eSIM roams on China Telecom (4G and 5G) on fixed plans and China Mobile (3G, 4G and 5G) on unlimited. A 5 GB plan for 7 days was US$14.63 on 23 September 2026, about US$2.09 a day and US$2.93 per GB, and it covers the week only if your calls home happen on hotel Wi-Fi.
Key takeaways
- Written for one trip: a first-time visitor in Beijing for five to seven days, living on maps, translation and QR payments, with a Great Wall day in the middle.
- The carrier is not a detail here. Fixed plans roam on China Telecom (4G, 5G), unlimited roams on China Mobile (3G, 4G, 5G). Fizen's eSIM Terms of Use state that mobile traffic may be routed through another country, which is why some apps can behave differently from a local SIM, but no page can promise you that a particular service will work. Check the Package details and do not build the trip on one app.
- Dated prices, per day and per GB: 5 GB for 7 days was US$14.63 on 23 September 2026 (US$2.09 a day, US$2.93 per GB). Unlimited for 7 days was US$27.38 (US$3.91 a day).
- After the high-speed bucket the line does not die, it crawls: most China Telecom plans drop to 128 kbps, which still moves messages and map tiles but not video calls.
The moment that ruins a Beijing arrival is small and specific. You clear immigration at Daxing, you have a hotel address written only in pinyin, a driver waiting somewhere, and your phone will not load a map. Everything you planned to lean on, the translation app, the ride app, the QR code for the taxi, needs data before it needs anything else.
Which Chinese network does a Beijing eSIM roam on, China Telecom or China Mobile?
This matters more in China than anywhere else, because there is no neutral option. The Fizen China plans are country plans, sold for China only, with no regional alternative to compare against. Fixed-data plans roam on China Telecom, on 4G and 5G. The unlimited plan roams on China Mobile, on 3G, 4G and 5G.
Beijing is about as well covered as any city gets. The municipal government reported in November 2025 that the city had built nearly 150,000 5G base stations, the highest number in the country. Inside the Second to Fifth Ring Roads, in the subway, around the Forbidden City and Qianmen, signal is not the thing that will go wrong on your trip.
What will feel different is what the network reaches, and that depends on the plan rather than on the city. It gets its own section below, and it is the honest reason to read past the price table.
What does a China eSIM cost right now, per day and per GB?
| Plan | Carrier and networks | Days | Total | Per day | Per GB |
|---|---|---|---|---|---|
| 1 GB | China Telecom, 4G and 5G | 3 | US$7.33 | US$2.44 | US$7.33 |
| 3 GB | China Telecom, 4G and 5G | 7 | US$10.09 | US$1.44 | US$3.36 |
| 5 GB | China Telecom, 4G and 5G | 7 | US$14.63 | US$2.09 | US$2.93 |
| 5 GB | China Telecom, 4G and 5G | 30 | US$15.64 | US$0.52 | US$3.13 |
| 10 GB | China Telecom, 4G and 5G | 7 | US$24.67 | US$3.52 | US$2.47 |
| 20 GB | China Telecom, 4G and 5G | 15 | US$39.30 | US$2.62 | US$1.96 |
| 50 GB | China Telecom, 4G and 5G | 30 | US$49.63 | US$1.65 | US$0.99 |
| Unlimited | China Mobile, 3G, 4G and 5G | 7 | US$27.38 | US$3.91 | not applicable |
| Unlimited | China Mobile, 3G, 4G and 5G | 30 | US$70.44 | US$2.35 | not applicable |
What happens when the data runs out?
The line does not switch off. The fixed China Telecom plans keep working at a reduced speed once the high-speed bucket is used: 128 kbps on the 3 GB and larger plans, and 384 kbps on the 1 GB plan. The unlimited China Mobile plan does not state a speed ceiling in the catalogue.
- 128 kbps moves text messages, map tiles that load slowly, and a ride-app booking. It will not carry a video call, and photos in a chat will take their time.
- 384 kbps adds audio calls and a usable map. Still not video.
- Neither is a disaster on the last evening of a trip. It is a disaster on day two, which is the case for sizing the plan properly rather than buying the smallest one.
How much data does a week in Beijing actually use?
| What you do in a Beijing day | Rough data | Note |
|---|---|---|
| Maps and navigation, on and off all day | 100 to 200 MB | Much lower if you download the offline map before leaving the hotel |
| Translation app, camera translation of menus and signs | 50 to 150 MB | Camera translation is heavier than typing |
| Ride app, hailing and tracking three or four trips | 50 to 100 MB | Small, but it must work at the moment you need it |
| Messaging, photos to family, email | 200 to 400 MB | Sending photos is most of this |
| One 30-minute video call home at 720p | About 0.55 GB | The single biggest line in the day |
| Photo backup to the cloud, if left on | 1 GB and up | Turn it off and let it run on hotel Wi-Fi |
Where does the signal thin out around Beijing?
Beijing's 5G figures describe the city. The Great Wall sections most visitors take a day trip to, Badaling and Mutianyu, sit 60 to 80 km outside it, in mountain terrain where a phone can hold signal on a tower and lose it in the next valley. The same is true of the Ming Tombs road and the reservoir routes north.
Treat it the way you would any mountain day: offline map downloaded, meeting point and return time agreed out loud with your driver or group before you leave the car park, and tickets saved as screenshots. Nothing about the plan you buy changes this. It is terrain.
