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?
+
In Taiwan, eSIMbundle connects to Taiwan Mobile. Your eSIM joins it automatically after landing, so you never need to choose a carrier. Taiwan Mobile supports 4G and 5G.
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. In the eSIMbundle app, open Store or Add data and buy a separate bundle on the same installed profile. Each bundle has its own allowance and validity and may wait before first use. Eligible finite bundles offer saved-card auto top-up at 80% used, up to your approved package price. Manage it under Account → Auto top-up; check existing replacement orders before buying again.
Should I buy my Taiwan eSIM before travelling?
+
Yes. Open the eSIMbundle app → Account → My eSIM → Set up your eSIM and use Install eSIM on this phone, or QR/manual fallback. Confirm the profile appears in phone settings. Installation does not start the bundle; first supported use in coverage does. At your destination, enable the line, select it for data and enable its Data Roaming setting. Keep the profile after the trip.
Does eSIMbundle include a VPN in Taiwan?
+
Yes. Use VPN inside the eSIMbundle app with your normal account. VPN connection requires an active qualifying bundle, including on Wi-Fi. Prepare the app before departure; a bundle awaiting first use may not yet provide access. Choose a country and connect. VPN does not guarantee access to every service.
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.
