eSIM Taiwan: Mobile Data From Keelung to Pingtung

With a Taiwan eSIM you skip the queue at an airport SIM counter. Everything is ready before you board: the plan is bought online, the profile sits on your phone, and after landing it only needs to be switched on.

Taiwan lies outside the EU roaming rules, so data on a European home tariff can add up quickly. A prepaid plan avoids that, and because it is data only, your regular SIM can stay in the phone. Your contacts keep reaching you on your usual WhatsApp number while the eSIM supplies the internet.

Coverage is listed for the following cities, and for other cities as well:

Taipei and the north

Taipei, Keelung, Taoyuan District, Zhongli and Hsinchu. Using your eSIM in Taipei means route planning for the metro, restaurant reviews and ride bookings work wherever the signal reaches.

The west coast

Taichung and Changhua, both handy stops on the way south along the western side of the island.

The south

Tainan, Kaohsiung and Pingtung. Old temples, harbour districts and the far south are all part of the listed coverage.

For Taiwan the standard order applies: install at home, switch on in Taiwan.

Start with your phone. It must be able to use an eSIM and must not carry a SIM lock from a carrier. Then buy the plan. You have 180 days after the purchase to activate it, and the validity only starts with the first connection to a supported network in Taiwan, so buying early does not shorten your trip.

Finally, connect to Wi-Fi and scan the QR code from My eSIM Plans. One scan is all the code allows. Leave the installed profile alone afterwards and never scan that code a second time. If something fails, our support team will help you.

When the plane has landed, open your phone's mobile settings. Turn the eSIM on, choose it as your line for mobile data and allow data roaming for it. Within a minute or two it should register with a local network.

No signal after that? A restart often helps, followed by switching airplane mode on and off. Also check that network selection is on automatic.

Whether you can share your data as a hotspot depends on the network operator. If tethering matters to you, for example for a laptop on a work trip, keep that in mind before you buy.

The connection runs on 3G, 4G/LTE or 5G, depending on the operator and your location. After heavy use, the operator may slow the speed under its fair-use rules. Photo backups and large downloads are best left for the Wi-Fi at your accommodation.

A data eSIM does not come with a number, so there is nowhere for an SMS code to land. When an app, a booking platform or an online service asks you to confirm by SMS, combine the eSIM with an Anosim number:

- Activation receives one code for a one-off sign-up.
- Rent Service holds a number for one service that may ask again.
- Rent Number gives you a number for any service you like.

If a number is virtual, it is labelled as such in the provider selection.
