China Unicom is one of the networks your eSIM may use in China. Here is who actually decides which network you get, and what to do with that.
Quick answer
China Unicom runs 5G on n78 (3.5 GHz, 200 MHz shared with China Telecom) and uses dynamic spectrum sharing on its n1 and n8 bands.
| Item | China Unicom |
|---|---|
| LTE (4G) | B1, B3, B8, B40 |
| 5G NR | n78 |
| 5G launched | 2019 |
| 3G | Shut down |
| Network code (MCC-MNC) | 460-01 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use China Unicom if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
Mobile networks in China are licensed, and their spectrum assigned, by the Ministry of Industry and Information Technology (MIIT). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
From the supplier record behind each package, 86 of the 103 plans we currently sell for China declare China Unicom as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
| Network | LTE bands | 5G bands |
|---|---|---|
| China Unicom | B1, B3, B8, B40 | n78 |
| China Mobile | B1, B3, B8, B39, B40, B41 | n40, n41, n78 |
| China Telecom | B1, B3, B5 | n78 |
A band shared across networks is one a single phone can use on all of them.
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If China Unicom is weak where you are, try selecting China Mobile or China Telecom manually in the network settings, and keep data roaming on for the eSIM profile.
86 of our plans name China Unicom as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
At least one of these, LTE: B1, B3, B8, B40; 5G: n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Yes. China Unicom has run commercial 5G since 2019, on n78. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.

Instagram and TikTok have no web share button, so we open your phone's share sheet or copy the link instead.
