What is the best eSIM for Taiwan?
+
For travellers who want Taiwanese mobile data on the phone they already own, eSIMbundle is a strong option. Buy a Taiwan bundle before departure, land at Taoyuan or Kaohsiung, and use Google Maps, HSR, Taipei Metro Go, Uber and LINE straight away. A VPN is included with every plan.
Which mobile network does eSIMbundle use in Taiwan?
+
Your eSIMbundle eSIM connects automatically to an available Taiwanese partner network when you land, so you do not pick a carrier at the airport. Taiwan is served by a small number of national operators; the specific one you end up on can vary by location and time.
Does eSIMbundle have good coverage across Taiwan?
+
Coverage is generally comfortable across Taipei, Taichung, Tainan, Kaohsiung, Hsinchu and Hualien and along the HSR corridor. Signal can weaken on Central Mountain Range roads, in Taroko Gorge, on long East Rift Valley stretches and on Alishan mountain trails.
Is 5G available with a Taiwan eSIM, and how fast is it?
+
4G is broadly available across populated Taiwan and 5G is generally strong across Taipei and other larger city centres. Whether your phone connects on 4G or 5G in a specific spot depends on your device, the available partner network and live local conditions.
How much data do I need for 7, 15 or 30 days in Taiwan?
+
Light users on Maps and messaging often manage on 1–3 GB a week. Normal travellers using HSR, Uber Eats, streaming and hotel bookings usually want 5–10 GB a week. Heavy video or hotspot users can push past 20 GB a week. Use the Travel Data Calculator to size a Taiwan plan for your trip.
Does a Taiwan eSIM include a Taiwanese phone number, calls or SMS?
+
eSIMbundle Taiwan plans are data plans. Use mobile data for LINE, WhatsApp, FaceTime and other internet-based calling and messaging. Keep your normal SIM active for calls, SMS and verification messages, subject to your home carrier's roaming charges and support.
Can I keep my normal SIM, phone number and WhatsApp?
+
Yes. On a compatible dual-SIM phone, keep your normal SIM installed and use your eSIMbundle eSIM for mobile data. Your normal phone number stays with your home SIM, and WhatsApp and LINE continue using the numbers already registered to your accounts.
Can I add more data while I am in Taiwan?
+
Yes. Sign in to your eSIMbundle account and add another Taiwan data bundle whenever you need more. The new bundle activates on the same eSIM already installed on your phone — no new QR code, no reinstall.
Should I buy my Taiwan eSIM before travelling?
+
Yes. Buy your bundle and install the eSIMbundle eSIM before departure while you have a stable internet connection. Then arrive at Taoyuan or Kaohsiung, turn off airplane mode and you are online — no counter detour and no roaming charges to worry about.
Does eSIMbundle include a VPN in Taiwan?
+
Yes. A VPN is included with every eSIMbundle plan at no extra cost. Switch it on in the app for a more private connection on Taiwanese mobile data and on airport, hotel and café Wi-Fi.
Does the eSIM work in Taroko Gorge and on Alishan trails?
+
In gateway towns and along main access roads coverage is generally comfortable. Inside the deepest Taroko Gorge switchbacks and on remote Alishan mountain trails, coverage from any Taiwanese carrier — including your eSIM partner network — can thin out. Offline maps are useful for those side trips.
Can I use the same eSIM on my next trip elsewhere?
+
Yes. Your eSIMbundle eSIM stays installed on your phone. When you travel to another supported destination, add a bundle for it in your account and it activates on the same eSIM — no new installation required.
