Chunghwa Telecom and travel eSIM in Taiwan

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.

Chunghwa Telecom and travel eSIM in Taiwan

Quick answer

  • 34 of the 34 Taiwan plans we sell name Chunghwa Telecom as a reachable network, at 4G and 5G.
  • Travel plans connect by roaming, so no plan can promise one specific network.

Chunghwa Telecom in brief

Chunghwa Telecom is a mobile network operator in Taiwan, and one of the networks a travel eSIM may reach through roaming. From the information we track, it runs 4G and 5G.

We are not a reseller for this operator and we have not run our own field speed tests. This page explains how the network relates to your plan; it is not a review of signal quality.

The plans on our shelf that name Chunghwa Telecom

From the supplier record behind each package, 34 of the 34 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, not from marketing copy, and it moves when the supplier revises the record.

A plan naming Chunghwa Telecom means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order remains the supplier's, and the signal where you stand still decides.

Why plans do not name a fixed network

Nearly every travel eSIM is a roaming product. The supplier holds agreements with one or more networks in the destination, and your profile picks between them by a priority order set inside the profile, not by the buyer. Two travellers on the same plan can end up on different networks in the same city.

The supplier's roaming agreementsThe plan's supplier
The priority list inside the profileThe plan's supplier
The bands your handset supportsYour device
Signal strength where you standPhysical location
How congested the cell is right nowThe local network

This describes how roaming works in general; it does not cite any specific commercial agreement.

The other networks in Taiwan

Alongside Chunghwa Telecom, the market also has Far EasTone, Taiwan Mobile, any of which your plan may use depending on the supplier.

  • If signal is weak in one spot, try manually selecting another network your plan supports
  • This market has 5G in parts of it, mostly in larger cities
  • Leave data roaming on for the eSIM profile: roaming is how the travel plan works, not an extra charge

UKK

Will my eSIM definitely connect to Chunghwa Telecom?+

34 of our plans name Chunghwa Telecom as reachable, but that is not a guarantee. Not necessarily. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are. Chunghwa Telecom is one of the networks operating in Taiwan, not a guarantee attached to any particular plan.

How do I see which network I am on?+

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.

Does Chunghwa Telecom run 5G, and will my plan get it?+

From the operator information we track, Chunghwa Telecom runs 4G and 5G. Getting 5G in practice needs three things at once: the plan permits it, your device supports it, and the area has coverage. Miss any one and you fall back to 4G.
