Mobile networks in Taiwan
A travel eSIM has no network of its own: it uses local operators. The plans for Taiwan list these:
| Network | Best technology | Plans for Taiwan only | Regional plans |
|---|---|---|---|
| Chunghwa | 5G | 0 | 5 |
| FarEasTone | 5G | 0 | 3 |
| Taiwan Mobile | 5G | 0 | 1 |
5G is listed on all of them. When a plan lists several networks, your phone picks one automatically and you can choose another in the network settings. 5G needs a 5G phone and 5G coverage where you are; elsewhere the eSIM uses 4G/LTE.

Switch on when you land
Turn on the eSIM line, choose it for mobile data and turn on data roaming for it. Keep data roaming off on your home SIM to avoid your own carrier's charges.
-
Give it a few minutes
The first connection can take a few minutes. The eSIM connects to Chunghwa, FarEasTone, and Taiwan Mobile.
