Chunghwa Telecom is one of the networks your eSIM may use in Taiwan. Here is who actually decides which network you get, and what to do with that.
Quick answer
Chunghwa Telecom's mobile coverage query page reports that its 3G base stations are now fully closed in all listed areas, leaving 4G/VoLTE and 5G.
| Item | Chunghwa Telecom |
|---|---|
| LTE (4G) | B1, B3, B5, B7, B8 |
| 5G NR | n78 |
| 5G launched | Live |
| 3G | Shut down |
| Network code (MCC-MNC) | 466-92 |
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 Chunghwa Telecom 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.
Chunghwa Telecom publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows Chunghwa Telecom's own network; a roaming plan may not get every technology it shows.
Mobile networks in Taiwan are licensed, and their spectrum assigned, by the National Communications Commission (NCC). 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, 45 of the 45 plans we currently sell for Taiwan declare Chunghwa Telecom 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 |
|---|---|---|
| Chunghwa Telecom | B1, B3, B5, B7, B8 | n78 |
| Far EasTone | B3, B7, B8, B28 | n78 |
| Taiwan Mobile | B3, B5, B7, B8, B28 | 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 Chunghwa Telecom is weak where you are, try selecting Far EasTone or Taiwan Mobile manually in the network settings, and keep data roaming on for the eSIM profile.
45 of our plans name Chunghwa Telecom 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, B5, B7, B8; 5G: n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Yes. Chunghwa Telecom has run commercial 5G, 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.
