Does the eSIM also work in the mountainous areas of Taiwan, such as Alishan or Taroko?

Largely yes. The Chunghwa Telecom and Taiwan Mobile networks cover most of the main tourist routes, including the scenic roads to Alishan and the busiest trails of Taroko National Park. In some very remote high-altitude areas or inside the deepest gorges the signal may weaken, but along the routes and in towns and villages the connection is generally stable.

Can I use the eSIM on the THSR high-speed train between Taipei and Kaohsiung?

Yes. The Taiwan High Speed Rail line runs along the island's western corridor, an area densely covered by the 4G/5G network. You can browse, stream content or work for almost the whole journey, with the odd short interruption in the longest tunnels — no different from European high-speed trains.

Do I need an adapter to charge my phone in Taiwan?

Yes. Taiwan uses Type A and B sockets at 110V, unlike Italy's 220–230V. Most modern smartphone chargers support voltages from 100 to 240V (check the label on your charger), but the plugs are shaped differently: Italian ones have round pins, Taiwanese ones have flat pins. A Type A or B adapter is therefore essential — buy it before leaving or look for one in department stores such as COSTCO or in Taipei's electronics chains.

Does the eSIM also cover Taiwan's smaller islands, such as Penghu, Green Island or Orchid Island?

Penghu (the Pescadores Islands) can be reached by plane from Taipei and has good 4G coverage from the main operators. Green Island (Lüdao) and Orchid Island (Lanyu), which are more remote and less populated, may have more limited or intermittent coverage inland; along the coastal roads the signal is generally present, but be prepared for a few dead spots.

How much does an eSIM for Taiwan cost?

eSIM plans for Taiwan start from €4.99. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Is an eSIM or roaming better in Taiwan?

A local eSIM in Taiwan is almost always much cheaper than the roaming of your Italian operator. In the European Union roaming is often already included ("Roam Like at Home"), but outside the EU the costs can be very high — with an eSIM you know the price in advance and pay only for the data plan you need.

Which operator or network does the eSIM use in Taiwan?

The eSIM in Taiwan connects automatically to local networks such as Chunghwa Telecom, Taiwan Mobile, Far EasTone — on 4G/LTE and, where available, 5G. Coverage reaches about 97% in inhabited areas. Your phone picks the best available network by itself.

Can I keep my Italian number with the eSIM in Taiwan?

Yes. Your Italian SIM and number stay active — the travel eSIM works alongside it as a data-only line. You stay reachable on WhatsApp, iMessage or Wi-Fi while you use the local network to browse. Traditional calls and SMS still go through your Italian number.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in Taiwan. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for Taiwan?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in Taiwan?

Yes. You can share the connection in Taiwan through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

How many GB do I need for Taiwan?

For a normal trip, 1–3 GB a week is enough for maps, messages and occasional browsing. With social media and photo sharing allow about 5 GB; for streaming, video calls or a hotspot count on 10 GB or more. If the volume is not enough, you can buy an additional plan at any time.

Taiwan is an island that surprises everyone who discovers it: Taipei is a hyper-connected metropolis where the Shilin night markets smell of scallion pancakes until midnight, while just two hours by train takes you to the Taroko gorges or the tea plantations of the Alishan mountains. But finding your way around the MRT metro system, the intercity buses and the lanes of Tainan's historic districts without internet is pure frustration. With a Datiovunque eSIM activated before leaving Rome, the moment you switch off flight mode at Taoyuan International Airport you are already up and running — map open, itinerary ready, landing message sent.

Flight from Rome

About 13–15 hours (usually with one stopover, e.g. Dubai, Amsterdam or Bangkok)

Time zone

UTC+8 (6 hours ahead of Rome in summer, 7 hours in winter)

Best season

October–December (mild weather, less humidity, no typhoons)

Power socket

Type A/B at 110V — adapter needed for Italian plugs

Why an eSIM is essential in Taiwan

Taiwan is one of the most advanced telecommunications markets in Asia: 4G/LTE and 5G coverage reaches 97% of the territory, thanks to top-tier operators such as Chunghwa Telecom, Taiwan Mobile and Far EasTone. This means a reliable signal not only in the heart of Taipei, but also along the coastal Suhua Highway, inside Taroko National Park and in the mountain villages of the interior. Buying a physical SIM at the airport is technically possible, but it means waiting at counters, showing documents and signing contracts in Traditional Chinese. With an eSIM all of this disappears: buy online from home, scan the QR code in a few seconds, and have your connection ready at take-off. One thing to keep in mind: Taiwan is on UTC+8, which is 6 hours ahead of Rome in summer and 7 hours in winter. Having working internet from the first moment means you can tell people back in Italy you have arrived without waiting for overcrowded public Wi-Fi — and in Taiwan days start early, with hot breakfasts at the morning markets and tours leaving at dawn.

Which eSIM plan fits you best?

Holidaymakers

Going away for 1-2 weeks? Pick a plan with 3-5 GB for maps, photos and messages.

Business travellers

For video conferencing and email while travelling, we suggest at least 5 GB or an unlimited plan.

Backpackers

A longer trip is better served by 10+ GB, or by a regional plan that spans multiple countries.

Families

For families with several devices we recommend a plan with tethering support and enough data.
