How International Roaming Works
A PikaSim eSIM is a foreign roaming line. In China it behaves the way any visitor's home SIM does on roaming: the local network carries the radio signal, and your data is routed out to the internet abroad.
The Path Your Data Takes
When you use a PikaSim eSIM in China, your data follows the standard international roaming path:
- Local tower: your phone connects to a Chinese tower for the radio signal only.
- Routing: the local network recognizes your SIM as a foreign roamer and routes your data out of the local network, as GSMA roaming standards describe.
- Exit point: your data exits to the public internet outside mainland China, in Hong Kong or Singapore depending on the plan. Each plan shows its IP location before you buy.
Roaming, Not an App
There is nothing to configure and nothing running in the background. Routing data out of the local network is simply how international roaming works for foreign SIMs, handled by the carriers' networks.
Local SIM vs. Roaming eSIM
| Step | Local Chinese SIM | PikaSim (roaming) |
|---|---|---|
| 1. Phone connects to tower | Chinese network (local) | Chinese network (roaming) |
| 2. Data routing | Through the local carrier | Routed out of the local network |
| 3. Internet exit point | China | Hong Kong or Singapore, depending on the plan |
| 4. Public IP | Chinese | Hong Kong or Singapore (shown on each plan) |
Which Local Networks It Uses
In mainland China your eSIM roams on the major national operators: China Mobile, China Unicom and China Telecom. The exact partner networks and speeds (4G or 5G) depend on the plan, and each plan lists them on the China eSIM page.
- Coverage: strong in cities and along major travel routes, thinner in remote rural and mountain areas
- Speed: set by the local signal and the plan; routing your data out to Hong Kong or Singapore adds a little latency, which is noticeable for gaming but fine for browsing, maps and calls
- Network choice: leave network selection on Automatic so your phone picks the strongest partner network
Plans and Pricing
Plans are prepaid data bundles with a fixed price and a set validity period, so there are no roaming bills afterwards.
- Sizes: from 1GB for a short trip to larger bundles for longer stays
- Typical cost: about $5 to $20 for a week of typical use
- Top-ups: add data to the same eSIM if you run low, no new install needed
- Data line only: keep your regular SIM for calls and texts while the eSIM handles data

FAQ
How does a roaming eSIM work in China?
Your phone connects to a Chinese tower for the radio signal only. Your data is then routed out of the local network and exits to the public internet outside mainland China, in Hong Kong or Singapore depending on the plan. Each plan shows its IP location before you buy. This is standard international roaming.
Which Chinese networks does the eSIM use?
It roams on the major national operators, China Mobile, China Unicom and China Telecom, depending on the plan. Each plan lists its partner networks and speeds on the China eSIM page.
Do I need to register with a Chinese carrier or show ID?
No. It is a foreign roaming line, so there is no local carrier registration. PikaSim asks for no ID and no account.
How fast is the connection?
Speed depends on the local signal and the plan (4G or 5G). Routing your data out to Hong Kong or Singapore adds a little latency, which is noticeable for gaming but fine for browsing, maps and calls.
How much data do I need for a trip to China?
For messaging and maps, 1 to 2GB per week. For video calls and some streaming, 5 to 10GB per week. Heavy streaming users should consider 10GB or more.
Will Chinese apps like WeChat and Alipay work?
